In 2012, a high school student who was the captain of a school basketball team committed suicide after suffering repeated corporal punishment from the head coach, who was a physical education teacher. This sort of tragic incident always prompts discussion about the current state of Japanese sports clubs. However, although such incidents occur repeatedly, Japan has not been able to eradicate violence in sports clubs. The purpose of the present study was to examine the reasons why Japanese society has tolerated corporal punishment by coaches or seniors in sports clubs, focusing on a popular belief that the roots of these practices lie in behavioral patterns that were prevalent in the old Japanese military during the Second World War. Initially, the paper proposes reasons why many people in Japanese society have believed and shared this view for a long time, although it has not been proven. Secondly, an attempt is made to reveal this as a problem for ordinary people who have consciously or subconsciously accepted corporal punishment as an intrinsic aspect of sports clubs, rather than considering it as an issue specifically for coaches or seniors. The following points were clarified: 1) For critics of corporal punishment, the “military origin theory” supports their opinions powerfully. Because this logic demonstrates the relationship between sports clubs and the old military, it is able to emphasize the problematic and inhuman nature of corporal punishment in sports clubs. This is one explanation for why this belief has been shared by many Japanese people for so long. 2) The “military origin theory” is a way of shifting the responsibility for violence in sports clubs away from the perpetrators. This has been supported by the general feeling of Japanese ordinary people against the old Japanese military. 3) The existence of violence in sports clubs reflects a degree of maturity in the general public viewpoint about sports by a considerable proportion of Japanese who do not or can not distinguish between hard training and violent behavior. Consequently, this belief negates the chances that many Japanese people consider corporal punishment in sports clubs to be their own problem.

The purpose of this study was to evaluate the utility of simplified quantification of training in for a Japanese national canoe sprint team using the modified session rating of perceived exertion method. We recorded the team's training using a method that integrates the original weighting factor (WF) and the duration (time) of the training session. Training load was quantified as the product of WF and time. Training monotony was calculated by as the mean daily load divided to the standard deviation of load. Training strain was calculated by multiplying the weekly training load by training monotony. A fitness-fatigue model was applied to the relationships between training load and performance. The model-predicted performance using the training load was significantly correlated with actual paddling performance. The training load and strain were significantly correlated with resting heart rate in the early morning. These results suggest that simplified quantification of training can be used to prescribe training for the improvement of performance and the prevention of overtraining syndrome.

The main purpose of this study was to verify the process of formation and development of the concept of aiki used by Morihei Ueshiba, the founder of Aikido, and his disciples. The main points can be summarized as follows: 1. The term aiki has been used to refer to particular martial arts techniques and to a spiritual state that can be experienced by practicing Aikido. Morihei taught aiki as a technique, as shown in the memorandum of the Japanese Imperial Navy Admiral Isamu Takeshita around 1930. Kisshomaru Ueshiba, Morihei Ueshiba's son, also introduced these techniques in his book, “Techniques of Aikido” (1962), etc. However, neither Morehei Ueshiba nor his son explained about aiki in detail. Kenji Tomiki and Gozo Shioda used aiki as a term of technique, but they do not seem to have taught techniques under the name of aiki. 2. Onisaburo Deguchi, the head of Omoto-kyo, used the expressions “the union between a kami and a mortal” in 1921 and “the great love of the kami” in 1935, which Morihei later emphasized in relation to aiki. Omoto-kyo heavily influenced the building of Morihei's thoughts on aiki and Aikido. Aiki was likened to the great love of the Universe, Heaven and Earth, or the kami who nurtures all nature and mortals. In short, a) aiki is the union between the kami as love, and mortals, hence the practice of aiki is the purification of mind and body; b) the practice of Aikido creates a paradise for mortals on earth; c) because the kami does not oppose anyone, a practitioner does not oppose in Aikido. Morihei's thought influenced the policy of the succeeding organization of Aikido through Kisshomaru. 3. Morihei's four main pupils inherited his thoughts through several arrangements. Shioda explained aiki as “a technique for following the laws of nature”. Tohei insisted that aiki is “the union between the ki in heaven and earth and a mortal”. Sunadomari interpreted aiki as a combative technique and a divine work. Tomiki understood the term in two ways: one is a technique that falls into the category of kuzushi (balance-breaking), and the other is the unity of ki (energy) between nature and man. As to the way that Aikido should develop in the future, we need to study further Morihei's thoughts and their development under his pupils.

The main purpose of this study was to investigate anthropometry and body composition in 26 male ultramountain runners who participated in Trans Japan Alps Race 2014, a multi-stage ultramountain running race over 415 km to be covered within 5-8 days. The second purpose was to investigate the changes in skinfold thickness during the race. Before the race, all participants were examined in terms of body weight, BMI, skinfold thickness at 8 sites and estimated percentage body fat. In addition, the finishers (n=14) were re-examined in the post-race period. The main findings are summarized below.1. The participants had a mean (±SD) body weight of 62.3±5.1 kg, a BMI of 21.5±1.4 kg/m2, a sum of 8 skinfold thickness of 57.7±15.5 mm, and an estimated percentage body fat of 12.0±2.4%. There were no significant differences in any parameters between the finishers and the non-finishers.2. The sum of 8 skinfold thickness in the finishers was significantly reduced by 11.3% after the race (Pre : 55.0±13.6 mm, Post : 48.8±12.1 mm), representing a dramatic response in comparison with a previous study that investigated ultramarathon runners in a 100-km ultramarathon race (0.9%).

This paper describes a historical study of “Yamatobataraki”, a form of gymnastics that was devised by Professor Kakei Katsuhiko around 1920 in Japan. The main study aim was to clarify how the practice of Yamatobataraki spread in Imperial Japan from the 1920s to 1930s. The diffusion process consisted of 3 phases. The first was associated with the growth of the Folk High School movement. Around 1924, Kato Kanji introduced Yamatobataraki to the Yamagatakenjichikoshusho, which was the original model of the Folk High School. Kato then transferred to the Nihonkokuminkotogakko, which was the head institution of the Folk High Schools, and introduced Yamatobataraki as part of its educational program. Kato's educational systems, along with Yamatobataraki, were reproduced throughout Japan and Taiwan, because the Nihonkokuminkotogakko helped to found other similar institutions. In the second phase, the Ministry of Agriculture and Forestry promoted the foundation of a large number of Nomindojo, i.e. farmers' schools. As a result, 50 farmers' schools introduced Yamatobataraki, because they were modeled on the educational system of the Nihonkokuminkotogakko. In the third phase, the Ministry of Colonial Affairs promoted the policy of agricultural emigration to Manchuria, and delegated the training of the emigrants to Kato Kanji. In 1938, Manmokaitakuseishonengiyugun, a large group of young agricultural emigrants to Manchuria, was institutionalized. Many young emigrants trained under Kato's methods in Uchiharakunrensho, which were formulated for the Manmokaitakuseishonengiyugun. Yamatobataraki as a daily routine was practiced as a matter of course. Thus, as described above, Yamatobataraki spread mainly via farmers' schools and emigrant training all over Imperial Japan due to the promotion of farmers' schools and emigration to Manchuria by the Ministry of Agriculture and Forestry and Ministry of Colonial Affairs.

Cross-country skiers perform over a long distance using poles and skis. Physical fitness, in terms of factors such as VO2max and muscle strength, skiing technique and race strategy are important for winning competitions. To plan the race strategy, investigations of the course profile and race analysis are needed. The purposes of this study were to investigate cross-country skiing course profiles which were planned for the Winter Olympic Games at Peyongchang, and to analyze the men’s 15km+15km World Cup skiathlon race (SA) as a pre-competition event. A cross-country skier followed the classical and skating courses using a GNSS (Global Navigation Satellite System) antenna. The antenna instantly measured the latitude, longitude and height of the skier on the courses. The coordinate values on a plane were calculated from latitude and longitude, after the inclination was then calculated from the coordinate values and height every 10 m. The overall finish time and transit time at 24 points for 12 skiers in SA were retrieved from the Official Home Page of the International Ski Federation (FIS), and the segment times among the various points were calculated. Three segment times formed a lap, and each segment speed was calculated by dividing the segment distance by the segment time. For the classical course profile, the distance was 3819 m and the maximum inclination was 18.6%. In contrast, for the skating course, the distance was 3777 m and the maximum inclination was 20.6%. No correlation was found between the overall finish time and the segment times for the classical course. This result was attributable to small variations in the lap times for the classical course because of the skiers’ use strategy, checking among competitors, and the mass-start. On the other hand, positive correlations were found between the overall finish time and the segment times on skating. In skating, the segment speeds from the final phase of the 2nd lap to the middle phase of the 3rd lap indicated deceleration relative to the 1st lap. These results suggest that gliding on a skating course in a short time is important for shortening the overall finish-time. Especially, it is important to minimize the deceleration of the 2nd and 3rd lap segment speed. The race pattern for the Olympic Games was similar to that of pre-competition, except for the time taken. These results indicate that pre-competition race analysis is useful for devising a strategy for target competition.

Previous studies have indicated that short-distance sprint ability is essential for achieving a high competitive level in soccer. However, there are no systematic data by which sprint ability in Japanese soccer players can be evaluated. The aim of this study was to develop an age-related evaluation chart for 20-meter sprinting time in male soccer players. The subjects were 807 high-level soccer players between 5th grade of elementary school and high school as well as 120 senior players including professionals. The sprinting time was measured on a grassed field using infrared photocell sensors with the subjects wearing soccer shoes. The sensors detected the release of the subject's rear foot at the start and the passing of the subject's trunk through the 20-meter position. The average time for field players decreased from 3.69(0.14) s for 5th graders to 2.98(0.08) s for seniors. The value for goalkeepers decreased from 3.79(0.12) to 3.07(0.11) s. Using the averages and standard deviations, an evaluation chart classifying the 20-meter sprinting time into 5 levels was presented for each age group. In addition, another chart taking birth date into account was also developed for 7th and 8th graders, since boys born earlier showed an advantage in the sprinting time. The time ranking for the fastest group in field players was less than 2.93 s for 9th graders and 2.86 s in seniors, resulting in a difference of only 0.07 s. In contrast, the value ranking for the slowest group exceeded 3.31 s for 9th graders and 3.11 s for seniors, resulting in a difference of 0.20 s. This implies that soccer players having lower sprint ability may drop out from the selection process as they get older. This evaluation chart can be useful for identifying the short-distance sprinting ability of soccer players in each age group.

In this study, we examined the effects of static stretching (SST) for different durations on muscle oxygen saturation (StO2) and muscle blood flow (BFmus) in the stretched muscles during and after SST. Nine healthy male subjects received passive SST of the wrist flexors. SST was performed for 10, 30, and 60 s. The StO2 and BFmus in the forearm flexor muscles were measured by near-infrared spectroscopy. BFmus was determined from the rate of increase in total hemoglobin during venous occlusion. StO2 decreased immediately at the start of stretching, and thereafter kept decreasing until the end of SST. StO2 replenished rapidly after completion of SST and remained above the resting level during the recovery period. For all 3 durations of SST, the peak value of StO2 during the recovery period after SST showed a significant increase above the resting value (p<0.01) (10-s SST: 72.5±2.8%, 30-s SST: 72.5±1.8%, 60-s SST: 73.0±2.2%). There was no significant difference in the increase in the peak values of StO2 after SST among the 3 SST durations. For all durations of SST, BFmus after SST increased significantly above the resting level (p<0.01) (10-s SST: 2.6±1.2 fold, 30-s SST: 2.8±1.6 fold, 60-s SST: 2.9±1.0 fold), but there was no significant difference in the increase of BFmus after SST among the 3 SST durations. These results show that SST of wrist flexors for 10 s, 30 s, and 60 s induced an increase in StO2 and BFmus after SST, but the increase in StO2 and BFmus was not affected by SST duration.

A three-dimensional (3D) videography study was performed to clarify the mechanical effects of a change of pitching motion from an overhand throw (OH style) to a three-quarter throw (TQ style). Two collegiate pitchers (subjects A and B) who normally used the OH style participated. They were requested to change their original OH style into the TQ style. To do this, they were subjected to a one-year skill training program based on biomechanical principles and on knowledge such as the stretch-shortening cycle theory, muscle force-velocity relationship, and the motions of skilled pitchers (e.g., shoulder positioning at 90 degrees of abduction-adduction during the acceleration phase). Four pitches for subject A (two in pre-training, one during training and one in post-training), and three for subject B (one each in pre-training, training and post-training) were videotaped with the 3D DLT procedure using two high-speed cameras, and then analyzed. We then examined the mechanical differences between pre- and post-training. The speed of the ball at release increased progressively with every successive pitch for both subjects (Subject A : 1st : 130.3km/h ; 2nd : 133.2km/h ; 3rd : 135.7km/h ; 4th : 142.2km/h. Subject B : 1st : 131.0km/h ; 2nd : 135.0km/h ; 3rd : 139.3km/h). The pitching styles of both subjects changed from their original OH style to the TQ style, both qualitatively and quantitatively. The time-dependent patterns and peak values of the angular velocities of shoulder internal-external rotation and elbow flexion-extension of the throwing arm did not change very much. However, the peak value of the angular velocity of shoulder internal rotation occurred immediately after ball release for the OH style, while for the TQ style it occurred at ball release. As a result, the angular velocity of elbow extension at ball release was larger in the OH style than in the TQ style. On the other hand, the angular velocity of shoulder internal rotation at ball release was larger in the TQ style than in the OH style. These findings suggest that the increase in the speed of the ball is dominated by elbow extension in the OH style, and by shoulder internal rotation in the TQ style.

This study attempted to identify initiatives regarding content and implementation of school physical education policies during March-August 1945, using data from Ministry of Education circulars. Its findings were as follows:  1. The historical development of school physical education administrative functions during the Asia-Pacific War was clarified. These functions were enhanced by establishing the Physical Education Bureau (January 1941). After 1942, these functions gradually diminished, and the Physical Education Bureau was absorbed into another department by July 1945. However, its functions did not become obsolete, and the policy planning and implementation initiatives were not suspended.  2. Regarding physical education policies after March 1945, the study first examined “Special Measures and Guidelines for Students' Physical Training” and “Special Measures and Guidelines for Students' Military Education” implemented in April 1945, and found that differences in content between the 2 reflected the degree of military involvement. The Course for Communication of Content to Local Regions as part of the former was also examined. Its characteristic features included nationwide implementation and dispatch of instructional officers to local regions to provide coaching and implement policy.  The study also examined the “Ministry of War and Ministry of Education Discussion Memorandum Regarding Deployment of Active Military Officers in School and the Wartime Special Measures for Regulation of its Enforcement” issued in July. This was construed as an amendment of previously stipulated regulations in accordance with circumstances at the time. School training measures were being continuously negotiated between the Ministry of Education and the military until just before the defeat. The “Special Measures and Guidelines for the Implementation of Female Students' Naginata (Pole Swords) and Self-Defence Methods” implemented in August were also examined. This confirmed that these guidelines constituted the last school physical education policy during the Asia-Pacific War.  3. The study re-examined the “Guidelines for Training of People's Fighting Power” (Kokumin Toryoku Rensei Youkou) established in May 1945, which previous studies had deemed the last school physical education policy during the Asia-Pacific War. This was a private recommendation based on martial arts created by Muneo Shiotani, and not an official Ministry of Education policy.  4. The present study has revealed details about school physical education policies during March-August 1945, which have not been examined previously. The findings are significant because they reveal that school physical education policies developed continuously during this late period of the Asia-Pacific War.

It is believed that the success of the goalkeeper (GK) in saving difficult shots by diving is a key factor in soccer because it can influence the outcome of the game to a large extent. However, the most appropriate way to exert force during the diving motion according to the course of the shot from either leg is still unclear. Therefore, the purpose of this study was to clarify the fundamental mechanism of a GK's diving motion according to the height and distance of the shot. We performed an experiment in which 11 university GKs participated. They were asked to dive toward balls set at 3 different heights located a short or a long distance from the GK. By examining the GKs' diving motions, we calculated the ground reaction force (GRF), joint angular velocity, and joint torque. The results indicated that the magnitude of the GRF under both legs and the direction of the GRF under the ball-side (BS) leg differed with the ball height. We also found that a higher dive by the GKs corresponded to a larger counter-movement of the contralateral-side (CS) leg and a higher stopping power of the BS leg in order to increase the vertical velocity, and more exertion of extension torques at the hip and foot for takeoff compared to those in lower dives. Furthermore, a lower dive of the GKs corresponded to a larger angular impulse of the BS hip adduction after the BS leg touched the ground. These findings suggest that during the takeoff part of the diving motion of a GK, depending on the ball height, the CS leg controls the magnitude of power and the BS leg controls both the magnitude and the direction of power in order for the GK to dive directly towards the ball.

The aim of this study was to clarify the establishment and development process of Dai Nippon Kyudo Kai (DNKK), which existed from the Meiji to the pre-war Showa era, and its organizational forms. The tasks of the study were to elucidate the establishment and developmental process of the DNKK based on the historical characteristics of the organization, which can be divided into 6 periods. The organizational forms were examined based on the articles of incorporation, and the trends of membership and branch distribution were also clarified. The results were as follows: 1)The DNKK was established as Seinen Kyujutsu Kai under the Toshizane Honda school in 1909, and shortly renamed the Dai Nippon Kyujutsu Kai. When it became an incorporated foundation in 1919, it was renamed the DNKK. The kyudo philosophy of Kako Neya was strongly reflected at the time of its foundation. 2)The DNKK increased its membership by developing its publishing arm, and promoted kyujutsu and kyudo as part of the regular curriculum in the school. 3)Division among DNKK members in 1915 and the death of Toshizane Honda in 1917 led to a schism of Toshizane Hondaʼs pupils, which resulted in diffusion of the Toshizane Honda method among kyudo players. 4)The DNKK was renamed kyudo from kyujutsu when it became an incorporated foundation in 1919. They considered kyujutsu to be a subject within kyudo. 5) The massive promotion of the DNKK was financially supported by kyudo shops. 6)Analysis of the articles of incorporation showed that the kyudo philosophy of Kako Neya was strongly reflected in the policy of the DNKK through a mechanism based on the opinions of the board of councilors. 7) The conflict with Dai Nippon Butoku Kai over kyudoyosoku resulted in further expansion of the DNKK because of the massive promotion program against them, and a medically negative interpretation to kyudoyosoku evident at the Tokyo Provisional First Army Hospital. 8)Kako Neya decided to step down in 1943, and the activity of the DNKK was substantially terminated in 1944 due to the influence of war. 9)The cumulative total DNKK membership was 22,769 between June 1912 and October 1943. The membership trend was affected by various external factors. 10)A total of 426 branches were established domestically and internationally. The trend of branch establishment was similar to that of membership, and 75% of branches were located in Eastern Japan. The DNKK aggressively promoted overseas expansion.

Recently, “Nijiku” sports motion theory has been proposed and is being widely disseminated for many types of sports events including association football (soccer). It appears that this theory has some scientific basis for improving performance in sports. However, as the theory did not follow the necessary procedures, to date, its scientific validity has never been examined. This paper was designed to precisely examine the scientific validity of the “Nijiku” sports motion theory in relation to soccer from the viewpoint of science philosophy and biomechanics. Falsifiability is an important concept in science. However, only a few objective data—the ground reaction force of the supporting leg during soccer kicking and the peculiar motion referred to as “unfasten knee” motion—were demonstrated in the related literature with incorrect interpretation, and there were no falsifiable data to prove the existence of “Nijiku” during sports actions. Thus, it has been considered that the “Nijiku” sports motion theory runs contrary to the principle of science. Moreover, there are many misleading descriptions, particularly with regard to the effect of gravity. As a result, it can be considered that the “Nijiku” sports motion theory is classified as a “pseudoscience” labeled inaccurately or misleadingly portrayed as science. Scientific counterarguments to stimulate debate on these matters by the proponent and/or supporters are expected.

The purpose of this study was to examine within-subject differences in bat-swing trajectory between intentional hitting towards the same field and towards the opposite field. 19 industrial league baseball batters and 16 collegiate baseball batters performed same-field hitting (SH) and opposite-field hitting (OH). The movement of the bat during the swing was recorded with two high-speed cameras (1000 fps) for 3D analysis. At the instant of ball impact, the striking surface of the bat faced towards the same field in SH and towards the opposite field in OH. The bat-head trajectory immediately before impact was directed obliquely upward in SH, whereas it was directed obliquely downward in OH. Throughout the swing, the projection angle of the bat on the vertical plane was greater in OH than in SH, and the ratio of the translational component of the bat-head speed to the resultant bat-head speed was significantly greater in OH than in SH. These results suggest that the characteristics of the bat swing in OH provide a suitable impact condition to drive the ball towards the opposite field, as evidence has demonstrated that (1) a batted ball is likely to travel towards the opposite field when the lower half of the ball is hit by a vertically inclined bat, and (2) the striking surface of the bat is unlikely to turn to face towards the same field when the contribution to the resultant bat-head speed is generated more by the translational component of the bathead speed than by the rotational component.

The purpose of this study was to clarify the handing down of a martial art in a Japanese village community, focusing as an example on the Shinto Katori-Ryu School.  The Shinto Katori-Ryu School was established in Kamigawara from the mid Edo period. Kamigawara was a farm village, and the members of the school were farmers. The Shinto Katori-ryu School was characterized by the following features.  1. There was no specific master exponent at the school, and the coaching was done by the village elders. Generally, at most Japanese martial art schools, a magnate or an authority acted as a master.  2. Only the eldest sons of the village were coached, and were referred to as sozokunin, meaning “heirs”. Learners at other schools are usually referred to as “pupils”, but this was not the case here. In order to become a sozokunin, a rite of passage known as kenjyutsu denjyu was necessary.  3. The school taught not only kenjutsu, but also methods of treating plague, and was dedicated to the god of a shrine. In addition, details of village regulation were also taught.  The Shinto Katori-ryu School was closely related to village affairs, and was aimed at educating people within the village. In this way it was recognized as a “folk movement” unique to Kamigawara. After the Meiji era, the school traditions were handed down until World War 2, while maintaining the relations close to local society. Therefore, after the modern era, it was not assimilated by budo and kobudo. Later, like many folk customs, the tradition was swept aside during the period of rapid economic growth.  The organization of a martial art has generally been understood as adhering to the iemoto system. However, the organization of the Shinto Katori-ryu School took a different form, and is one example of a martial art that was nurtured and handed down by farmers.

Matsuo Basho is considered to have been a hardy walker. The present study was conducted to examine Basho’s walking ability in detail, focusing on his travels in Okunohosomichi. Kawai Sora accompanied Basho on his trip, and this study drew upon Sora Tabinikki, which were notes left by Sora, as a basic historical document. The results obtained were as follows. 1. Basho walked a total distance of 1728.1km, covering an average of 28.3km per day. The distance he walked in a day was mainly around 20–30km. On days when Basho walked for a longer distance, he walked up to 40–50km. However, a look at the distance walked indicates that Basho’s walking ability was inferior to that of an average traveler of the early modern period (an average male). 2. Basho maintained a certain pace over the course of his journey. Each day, he walked at an average speed of 3–4km for about 5 to 8 hours. The upper limit of the distance walked was about 50km a day, but that was a typical distance for people of the early modern period. 3. Records of a trip from Tohoku to Ise during the same period as Basho’s trip and records of a trip from Edo to Tohoku along a similar route 88 years after Basho’s trip were examined. The results indicated that the distance walked in a day during both of those trips far exceeded that walked in a day by Basho. 4. Basho’s age (46 years) meant that he was an older traveler for the early modern period, but Basho walked at a certain pace from start to finish despite stifling heat, rainy weather, and changes in the lengths of days depending on the season. 5. Basho encountered dangerous sites along the way. At times, he walked in dunes where he lost his footing in the sand, he looked nervously at mountain passes that were said to be impassible, and he traversed dangerous shorelines pounded by angry waves with the weather’s help. These findings indicate that Basho’s walking ability was inferior to that of average people of the early modern period in terms of distance, but it was not affected by the weather or season. Basho maintained a certain pace despite occasional dangers along the way. This is what distinguishes Basho’s walking ability.

The present study investigated the transformation that has occurred in Muay Thai, a traditional martial art in Thailand, as a result of gambling. Muay Thai is a sport that incorporates religious ceremony. In Thailand, gambling has been conventionally illegal. The rules of Muay Thai have not been changed since Rajadamunan stadium was established in 1945, and Muay Thai has since developed into a national amusement and become a modern sport. However, various gambling styles linked to Muay Thai still continue to exist. Such gambling comprises three types: 1. Gambling on matches, where all the prize money is placed in bets. 2. Gambling through bookmakers. 3. Gambling based on odds, with no restriction on who gambles and how much money is staked. Since the late 1970s, however, gambling based on odds has increased, and this has resulted in a change of Muay Thai game tactics. Currently, most of the audiences coming to Muay Thai stadiums are gamblers who use odds to bet. For this study, data were collected through fieldwork conducted at Muay Thai stadiums in Thailand. Data were also gathered from Muay Thai magazines. These data have been reconstructed in order to examine how Muay Thai has changed in response to gambling, and the results indicate that the game tactics of Muay Thai have changed due to odds gambling. As a consequence, Muay Thai has become not only just a martial art, but also a sport for gambling.

With the enforcement of various sport policies with a focus on strategic and comprehensive community sport clubs promotion, debate over the management form of extracurricular activities in Japan has been more focused on the trend of relationship-building both inside and outside of school. In this study, we discuss the validity of the club management form that is centered on activities inside the school, in an attempt to critically consider relationship-building trends. For this, we examine cases where a relationship has been initially formed, but then dissolved, by means of an interview survey with some teachers involved.   The relationships formed in comprehensive community sport clubs and extracurricular activities were achieved through the aggressive behavior of a single health and physical education teacher. Many school teachers in Japan feel responsible for the day-to-day club guidance. Therefore, cooperation with school sport activities outside the school is also open to other teachers. However, with regard to relationships with out-of-school activities, the consciousness of teachers began to change. In this study I confirmed the occupational culture of teachers, which involved “complicated efforts to build up relationships with local residents”, “a sense of extracurricular activities in school education,” and “indifference to out-of-school activities”. In fact, building relationships between comprehensive community sport clubs and extracurricular activities ended in failure.   Thus study has highlighted a drawback of current sports policy content in Japan. Current sport aims at the creation of a sports environment in all regions, including schools. However, no consideration seems to be given to the viewpoint of teachers who have supported sport in school. As long as there is no form of club management where teachers are indispensable, the situation in Japan would appear to be difficult.

This paper focuses on the position of “Ju-ken” matches and their promoter, Kenji Kano, in Japanese boxing history. A “Ju-ken” match was a match between a judoist and a boxer, and such bouts were held from the middle of the Taisho era to the early Showa era in Kobe, Tokyo and Osaka. The main organizer of these matches was the “International Ju-ken club”, whose owner Kenji Kano was the nephew of Jigoro Kano. This study divides the history of Ju-ken into three periods, each with respective features.   The first period was from October 1919 to April 1920. Ju-ken at this time was intended to reform judo into a competitive sport through fighting with boxing. Although judo had been well established at that time, it was facing a challenge due to loss of its spirit and form as a martial art during the process of sportification. Jigoro Kano, the founder of Judo, was unhappy with this change. By studying boxing, karate, aikido, stick fighting and other martial arts, he aimed at creating a ‘Martial Art Judo’. His nephew Kenji Kano pursued martial art-oriented judo as well, but his approach to reconstructing judo as a martial art was through mixed martial arts games, the “Ju-Ken math”.   The middle period was from May 1920 to March 1925, when Ju-ken evolved into a spectator sport that encapsulated the struggle for superiority in terms of nationality and ethnicity. Because Kodokan prohibited their members from participating in any mixed-martial arts match from April 1921, Ju-ken became a spectator sport. In addition, after charity matches following the Great Kanto Earthquake, in order to bring more excitement to the game, Ju-ken heightened the opposition and rivalry based on the nationalities and ethnicities of the athletes.   The final period was from May 1925 to August 1931, when Ju-ken changed into a show that was intended to provoke nationalistic emotions among the audience. After the development of “normal” boxing, Ju-ken held normal boxing matches in their games and adopted new boxing-like rules. These new rules and the point systems put foreign boxers at a disadvantage when fighting against Japanese judoists, ensuring that Japanese would always defeat foreigners.   Finally, through assimilation of knowledge and focusing on boxing, this study argues that Ju-ken matches created a background for localization of modern boxing in Japan.
