From the world to Japan.
WATARIDORI PROJECTS is our international exchange business built around sports. We host overseas teams for tours and training camps in Japan, and we send Japanese players to Europe on study-abroad programs.
Our CEO, Kazusa Katayama, played and managed in the German Baseball Bundesliga. He knows what it is like to play abroad and what it takes to welcome players from abroad, and our staff handle everything from preparation to on-site support.
