The only real restriction set on the sport is that the participating tanks can not be heavier than 10 tons, which means only light tanks and tankettes can be used. Being an unofficial sport also means teams are fighting more for bragging rights than championships or prizes, though the latter can be part of the agreed match. The sport especially appeals to those school ships that either can't afford a formal sensha-dō team or can't afford to field anything bigger than a light tank.
