One of the characteristic culture of Budo is to exist of many schools in Budo. As the conditions of a school formation in Budo. S. Nakabayashi pointed out(1) A founder is born and discoverd a trick,(2)A trick is arranged (3) Arrange of instruction. But there hasn't been illustrated on the point of the conditions of a school formation in Jujutsu, yet. And so we considered the conditions of a school formation in Takenouchi-Ryu-Jujutsu being the first appearance in Jujutsu.<br>The results were as follows:<br>1) Hisamori Takeuchi, a founder of Takenouchi-Ryu-Jujutsu was the head of a family and went on knight errantry in order to himself. At last he founded Takenouchi-Ryu-Jujutsu in 1532.<br>2) The second established a Law, Keeping a trick from another and making a courtesy with pupils. He made HEIHO-KA and lectured pupils preparation for battle according with Zen.<br>3) The third invented the system of promotion, for example from entrance to be up to Tassha, Mokuroku, Zirou, Menkyo and Inka. He instructed the trainer KATA from easy to difficult in accordance with the system of promotion.

The &ldquo;concept of a double-edged sword, &rdquo; which we often hear about in kendo and swordsmanship, is a symbolic reference to the sacred sword (Kusanaginotsurugi) of the three sacred treasures. The three sacred treasures themselves have very unique circumstances surrounding them, and the image of Kusanaginotsurugi, which is one of the three treasures comprising the imperial regalia, represents the &ldquo;concept of a double-edged sword&rdquo; and describes this most symbolically. The &ldquo;concept of a double-edged sword&rdquo;itself departed from the field of faith and religion in ancient Japan, and had another value system differing from that of the martial art. Then, in the Edo period, the &ldquo;concept of a double-edged sword&rdquo; was determined as a benchmark that symbolized the cultural nature of the martial art. Namely, that the &ldquo;concept of a double-edged sword&rdquo; passed through various changes during the medieval era, and it was the Kusanaginotsurugi, one of the sacred treasures, that represented this notion.<br>This study aims to identify the circumstances surrounding the &ldquo;concept of a double-edged sword&rdquo; from the perspective of the three sacred treasures, paying special attention to the medieval era.<br>In this research, the circumstances in which &ldquo;the concept of a double-edged sword&rdquo; came to combine with the martial art, and the subsequent directionality are clarified by examining the notions regarding the three sacred treasures in the medieval era. The contents are described as follows and are summarized for each period.<br>(Heiancho Period or before)<br>*The sacred treasures symbolized gods prior to the Imperial Throne, and without this structure, they could not symbolize the Imperial Throne adequately. In other words, a dual structure existed, in which the sword was a ritual utensil and simultaneously a ceremonial arm.<br>*At that time, the structure in which the sacred treasures symbolized the Imperial Throne was not as significant as the role played in society.<br><Kamakura Period><br>*The samurai class represented by Genji and the Heike considered the three sacred treasures to be very important symbols of the Imperial Throne. The role this idea played in society became very influential.<br>*Such tendencies were originated in the samurai's adherence to positions of the Emperor's military (Imperial army), because only the adherence affirmed their usage in military force.<br>*Since only the Kusanaginotsurugi was lost among the three sacred treasures, this sacred sword conversely attracted more attention and was regarded as important; consequently, it began to be treated as a special object. Though the sword was originally a ritual utensil and a ceremonial arm, it came to be treated as an element of the martial art.<br>< Nanbokucho/Muromachi Period><br>*The three sacred treasures of the Imperial House became common.<br>*Symbolism without the actual existence of Kusanaginotsurugi began to appear.

In the field of Budo, mokusou (meditation) is a means of controlling mind and body as a part of the training regimen, and approximates meditative practices in Zen. During meditation, the budo practitioner maintains a prescribed posture, regulates his (or her) respiration, and controls activities of his consciousness. There can be no doubt that this psychosomatic control produces a special form of mental activity.In order to investigate brain wave activity during meditation, the brain waves of three kendo and three judo practitioners were monitored and recorded at 13 locations on the cranium (i. e., FZ, CZ, PZ, F3, F4, T3, T4, C3, C4, P3, P4, T5, and T6), in accordance with the 10-20 electrode system. The brain waves were processed by fast Fourier transformation for calculation of the power spectral values. In order to consolidate the immense amount of data, factor analysis (identification of factors, based on maximum likelihood, and EQUAMAX rotation) was performed to extract five factors (i. e., delta, theta, alpha-I, alpha-II, and beta). In addition, an analysis of variance (ANOVA) was performed for scoring of the five factors for the purpose of comparing brain wave activity during meditation with that during rest. By this comparison we found a significant disparity in the cases of the theta and alpha-II factors. The brain wave activity represented by these factors was lower during meditation than during rest.Since meditation as practiced in budo is a training method akin to that employed in Zen, it was initially anticipated that the frequency of alpha waves monitored during it would be lower. However, investigation of the spectral distribution during meditation determined that the wave frequency tended to be higher rather than lower. This relative increase of the frequency of alpha-wave is a phenomenon that has been found in the brain wave patterns of masters of Qi-gong during Qi-gong practice. It is conceivable that this increase in frequency is caused by the high-order activity of the consciousness accompanying the process of conjuring up images during meditation.

In ancient Japan, the concept of gods had been changed as passing of time. From this fact, it is expected that Japanese primitive faith had been changed, as sword culture was transmitted from China. In this paper, we describe transformation of primitive belief and foundation of unique Japanese sword culture, in the process of accepting sword culture.<br>The summary is as follows:<br>1. Sword culture influenced ancient Japanese mental world, and changed belief in the fire. This belief in the fire changed from destructive to constructive and part of this had been absorbed in the concept of sword.<br>2. Originally, ancient people believed in god of snake that supported farming. But, as the time went by, power of god of snake had declined, and this faith was absorbed in the concept of the sword.<br>3. Power of god of thunder had decline, too. The belief in this had concentrated at peculiar god "Takemikazuchi", and this had been related to sword.<br>4. The sword came to absorb concepts of fire and snake. And related to "Takemikazuchi", it was recognized as god itself.<br>5. From the above discussion, it is assumed that there is a unique Japanese way of thinking that sword is related to god. This is thought to be a foundation of concept of sword in Japan.
