This paper analyzes spatial distribution of a sports school (swimming and gymnastics) members and usage of school bus. This school is close to a railway station on the outskirt of Tokyo Metropolitan area. The obtained data was the membership list including membership code, sex, age, membership type, and home address. The information on the school bus such as bus users list, location of bus stop, and bus route map was also provided by the school. The findings of the analysis are summarized as follows: (1) Most of the members reside within 3km radius or 3.5km road-distance area from the school. (2) The exponential relationship between road-distance and the participation rate was observed. (3) Approximately 91% of the school bus users reside within 500m road distance from the nearest bus stop. (4) Only 21% of the members living within both 1-3.5km road-distance from the school and 500m road-distance area from the nearest bus stop use the school bus. The results of this study suggest that school bus service is not necessarily efficient in attracting a large number of new customers.
