MBIS has a very proud athletic tradition. Despite its relatively small size, the school has managed to acquire an impressive list of championships throughout the years. We are also widely recognized for our sportsmanship and good character on and off the sporting fields and courts. In the last two decades alone, MBIS has claimed over 200 championships and tournament trophies, within the local region and beyond, including overseas invitationals.

Our Middle School (grades 6-8) and Varsity (grades 9-12) programs offer opportunities to play five sports over four seasons: Volleyball, Soccer, Basketball, (Boys) Baseball and (Girls) Softball. As members of the Western Japan Athletics Association (WJAA), we compete in regional leagues and tournaments against other international and US base schools, as well as occasionally coming up against teams from as far away as Tokyo and Hokkaido. Students may also have the opportunity to compete in tours and tournaments abroad. MBIS also hosts an annual Invitational Futsal Tournament for students in grades 3-6, competing against other international schools in the region.

Being a small school, all students can “make the team”. We believe that our athletic program is more than an opportunity to increase fitness and physical ability – students have frequent opportunities to develop skills that will serve them well throughout their lives. Dedication to sports means a dedication to practice, risk-taking, hard work, self-discipline, teamwork, fair play, leadership, and so much more.

The MBIS athletic facilities include a full-size gym, well-stocked weight room, and a synthetic grass sports field. Campus games and tournaments are organized by the very popular Marist Athletic Association (MAA), providing opportunities for students to work behind the scenes, as well as on the court.
