The All-Japan Judo Championships (AJJC) is an open-weight tournament for determining the best judoka in Japan. The AJJC has been held under the Kodokan Judo Refereeing Rules (KDK Rules) since 1951. In 2011, the All-Japan Judo Federation (AJJF) introduced the International Judo Federation Refereeing Rules (IJF Rules), which were formulated to facilitate more dynamic judo (increased wins by ippon, decreased wins by judges' decisions, and decreased mate-time). Although the IJF Rules has facilitated dynamic judo in international competitions, their effects on the competition contents in the AJJC are still unknown. Here, we aimed to clarify whether the introduction of the IJF Rules facilitated dynamic judo in the AJJC. The 221 judo matches in the AJJC from 2008 to 2013 were separated into two groups, the tournaments following the KDK Rules (2008-2010) and those following the IJF Rules (2011-2013). Their data were extracted from the AJJC records by Judo, the official Kodokan journal, and from the match videos recorded by the AJJF. We analyzed the proportions of winning contents (wins by ippon or superior performance), winning methods (points from techniques or penalties, or judges' decisions), techniques for getting points (te-waza, koshi-waza, ashi-waza, sutemi-waza, or katame-waza) and the mate-time for each match. A chi-square test and an independent t-test were used to perform statistical analyses, and for each test, statistical significance was assumed at P value < 0.05. For the winning methods of the IJF Rules' and the KDK Rules' tournaments, the proportion of points from techniques (60.4% vs. 53.6%) and points from penalties (23.4% vs. 15.5%) showed no differences, but the proportion of wins by judges' decisions in the IJF Rules' tournaments was significantly lower than in the KDK Rules' tournaments (16.2% vs. 30.9%) (P < 0.05). Furthermore, the mate-time in the IJF Rules' tournaments was significantly shorter than in the KDK Rules' tournaments (77 s vs. 105 s) (P < 0.01). However, the winning contents and techniques for obtaining points showed no differences between the IJF Rules' and the KDK Rules' tournaments. We confirmed for the first time that the IJF Rules did not affect the winning contents and techniques for getting points, but decreased the proportion of judges' decisions and mate-time in the AJJC. These findings suggest that the IJF Rules partially facilitated dynamic judo in the AJJC.

Judo, which has become popular in more than 200 countries and regions, has developed while merging with both national and ethnic sports. Among them, chidaoba practiced in Georgia is a remarkable example of anethnic martial art. However, no literature in Japan has yet described the technical form and historical background of chidaoba in detail. Therefore, the purpose of the present study was to clarify the essence of chidaoba by considering its historical and cultural background. The author has mastered basic Russian language skills and performed a search for academic essays and websites using keywords such as chidaoba or Georgia and ethnic martial arts in Russian. To ensure accurate translation from Russian into Japanese, the text was checked by several Japanese with native-level Russian language skills. Chidaoba matches were held on Christian holidays such as Saint George’s Day and the Svetitskhoveli Cathedral Holiday. Thus, chidaoba took root in cities and rural areas as an irreplaceable festival event. Later, when the Christian church banned some forms of ethnic entertainment and physical exercise, only chidaoba was exempt. Before a match, competitors were obliged to perform the traditional dance, kartuli or palavnuri. In chidaoba, any type of grasping from the waist and upper body is allowed, while grasping below the waist is prohibited. There are a wide variety of techniques in chidaoba, such as throwing from close contact, foot throwing, foot sweeps, reaps, and hooks. Due to the diversity of Georgians, ethnic groups vary from region to region. Moreover, there are several different forms of martial arts in the mountainous areas of Georgia, which are very different from chidaoba. In 2018, chidaoba was registered as an Intangible Cultural Asset. The results of this research should serve as a basic material for clarifying the outline of the Georgian ethnic martia art chidaoba.
