    The purpose of this paper is to (1) examine the operational definition of “Locally originated sports”, (2) collect and organize examples, (3) categorize and publish their actual images in an academic journal. “Locally originated sports” are recognized as an entity that can contribute to “improving the quality of life”. They can also enhance the vitality and attractiveness of a town. This can happen in the context of “regional revitalization and community development”, with the implementation utilizing unique local resources.

    In today’s world of competitive sports, objective analysis based on scientific data collection is gaining more and more importance for improving athletic prowess. However, capturing and scrutinizing table tennis dynamics through video analysis is challenging because of the diminutive size of the ball and the rapid pace of rallies compared to other ball-based sports. Therefore, the authors are in the process of developing a system designed to harness a microphone’s capabilities to collect quantitative insights such as the drop position of the table tennis ball and the point of impact between the racket and the ball. The aim of this study is to essentially analyze the distribution pattern of the ball. By measuring vibrations of the ball using a microphone, the estimated position of the ball can be derived through time differentials. This approach extends to measuring the impact position of the ball on the ping-pong table, offering a three-dimensional snapshot of the racket and ball interaction. As a preliminary step in developing a system that delivers precise quantitative values, the authors verified the estimation of ball drop positions and racket impact locations during free falls as well as rallies. It was noted that the error margin for estimating free-fall position ranged approximately from 1 to 4 cm. During rally tests, there was almost no error in the descent position, similar to free fall scenarios. However, the racket impact position exhibited an error of approximately 10 to 20 cm, indicating that it is possible to roughly determine the position. Going forward, the system has to be refined to bolster its usefulness as a real-time tactical analysis tool, enhancing its capability to provide instantaneous estimations of position.

    The aim of this study was to focus on the pre-retirement activities of sub-elite and non-elite football players. The study tried to determine how football players prepare for their second careers and the relationship between their activities and their career choices. Semi-structured interviews were conducted with 11 players who had left JFL clubs within five years and had taken up non-competition-related jobs. The survey was conducted on specific activities during active service, reasons for retirement and career choices after retirement. The activities were in chronological order from before retiring from competition to choosing a second career. The results revealed the following behavioral characteristics of the athletes with regard to pre-retirement activities: “building relationships with people outside of competition” and “employment experience”. It was revealed that through these experiences, the players explored their next careers and their suitable jobs while they were still active, and that these proactive orientations influenced their choice of occupation after retirement.

    Purpose This study examined the multiple factors influencing the consumption behavior (game attendance frequency, intentions to attend future games and purchase merchandise) of B. League (Japanese professional basketball league) spectators. Methodology Based on a literature review, this study assumed that B. League spectators’ consumption behavior could be explained by the interaction of four factors: spectator motives, team identification, game attractiveness, and facility. We propose an expanded instrument created by adding subscales to Won and Kitamura’s (2006, 2007) motivation scales. We tested the proposed model within the context of B. League spectators by conducting a CFA. Findings The modified instrument exhibits satisfactory psychometric properties. The findings indicate that the multiple-factor model explains 42% of the variance in game attendance frequency and 79% in future consumption intentions. Entertainment was the strongest predictor—and game attractiveness was a new predictor—of current game attendance frequency. Team identification was a crucial predictor of future consumption intentions.

    Enhancing menstrual health literacy is crucial for adolescent health, however school curriculums often lack comprehensive content on this topic. Menstrual issues such as dysmenorrhea significantly underscoring academic and athletic performance, highlights the need for more comprehensive education. This review focuses on critical health literacy among adolescents in Japan, analyzing current educational practices and proposing an integrated approach. Our literature review indicates that while educational programs improve functional literacy, they often frequently fail to cultivate the critical literacy necessary for changing perceptions and behaviors. This study proposes an educational framework that includes interactive workshops and insights from the 1252 Project, aimed at improving menstrual health through lived experiences and expert knowledge. Current findings suggest that comprehensive menstrual health literacy enhances knowledge and attitudes and also promotes healthier behaviors among adolescents. Additionally, the importance of training educators to facilitate open discussions confidently is emphasized. In conclusion, a holistic approach to menstrual health literacy in schools is essential for supporting adolescent girls and overall health, urging improvements in educational strategies.
