In competitive sports such as Kendo and Karate, it is necessary to attack rapidly before the opponent initiates attack or defense situations. This study investigated the relationship between Issokuitto-Men (IM), Tsubazeriai-Hiki-Men (HM), and Toma-Men (TM)’s striking reaction time (RT) and lower-extremity stretch shortening cycle (SSC) performance. Twenty-four university male Kendo players aged 18 to 20 years participated in this study. All participants completed the simple and choice reaction times on the whole body (WB), IM, HM, and TM conditions, rebound jump (RJ), standing broad jump (SBJ), single leg drop jump (SLDJ) for stretch-shortening cycle (SSC) performances. Pearson’s correlation coefficient was calculated between simple and choice reaction times and SSC variables. Significant relationships were only found between SJ with single leg backward direction (r=-0.449). Furthermore, there was no difference in the simple and choice reaction times of the various strikes between regular and non-regular players, and it is possible that their abilities are close. These results indicate that the simple and choice men’s striking reaction times are not related to Kendo players’ SSC performance.

　The purpose of this study is to clarify the kendo spread activities（dojo and schools） of Nakwon Kang（NK）in Korea under Japanese rule（1921-1942）. The method was based on historical analyzing documents（mainly organization’s documents and newspapers realated to NK）. The results are as follows:

１）At the Korean Budokan（1921-1942）, NK implemented the kendo spread activities（holding kendo competitions, conducting mid-winter training, dan/kyu examinations, organizing the kendo expedition team, etc.） in order to promote the unification of the Korean Budo community and the training of the mind and body of the Koreans.

２）At Yeonhee College（1929-1941）, NK taught Kendo to foster students with the harmonious combination of knowledge, moral, and body. The final position of NK in Yeonhee was the head of Budo department and associate professor.

３）At Ewha Womans College（1935-1941）, NK conducted mid-winter training and kyu examination as a master of the kendo department for the purpose of training the female students’ mind and body. Through the examination, NK gave birth to the first female student “kyu” holder in Korea. In conclusion, given the results above, the NK’s kendo spread activities promoted the organization of kendo in Korea（management of competition, dan/kyu examination）for the mind and body training of Koreans through the dojo and schools. and they characterized both the cultivation of “dan/ kyu” holders and expanding the kendo population throughout Korean society.

In the 2018 revision of the High School Course of Study, “prevention and recovery from mental disorders” was positioned as one of the contents of the subject on health. The purpose of this study was to examine the awareness of teaching about mental disorders among university students who obtain teaching certificate for health and physical education of junior high school or high school. In March 2022, using a semi-structured interview method, we conducted interviews of five senior students who belong to the department of physical education at an university in the Kanto region and who will plan to proceed to graduate school in the next academic year. The interview data（utterances） were transcribed and analyzed by the thematic analysis method. As a result, three themes were emerged: “Insufficient acquisition of knowledge about mental disorders”, “Negative image of mental disorders”, and “Motivation to improve guidance on mental disorders”. To improve guidance on mental disorders, first of all, in the teacher training stage, from the fact that mental disorders are a common condition that anyone may potentially get, it is necessary to treat them as a personal problem and motivate students to acquire knowledge on these diseases. In the future, it will be even more necessary to dispel erroneous assumptions on the basis of corrective knowledge and experience and to provide university students with a concept of actual teaching and confidence by presenting specific teaching materials and teaching methods in classes on mental disorders.

　As budo continues to develop internationally, questions of how practitioners abroad perceive budo and how budo-related terminology should be translated has become a pressing issue in recent years. This study focuses on the writings of Donn Draeger. Draeger contributed to the international understanding of budo and has exerted a major influence on non-Japanese practitioners. By investigating Draeger’s usage of the terms “bujutsu”, “budo”, “martial arts” and “martial ways”, all of which are used to indicate “budō”, we aim to clarify his views on Japanese martial arts. In his books Classical Bujutsu, Classical Budo and Modern Bujutsu & Budo, Draeger mainly used the words “bujutsu” and “budo” when describing the martial history, culture, and spiritual aspects he learnt in his study of martial arts. The terms “martial arts” and “martial ways” were introduced for the benefit of non-Japanese with no knowledge or experience of bujutsu or budo. These English terms do not have the same depth implied by “bujutsu” and “budo”. Draeger makes a distinction between “bujutsu” and “budo” in different periods, stating that the purpose differs between “classical bujutsu”, which was designed to kill, and “modern bujutsu”, which aims to subdue the opponent. On the other hand, Draeger considered “classical budo” with its strict sense of spirituality to be more ideal than “modern budo”, which has other objectives to spiritual training such as entertainment or sport. He also thought that classical bujutsu and budo have more value than its modern incarnations.
