Mizuno is a Japanese company established in 1906 and it has specialized mainly on sports and outdoor clothing. The product line Blue Impulse was advertised with this game. Under this label Mizuno carried clothing and accessories for skiing. The interesting fact about the game is, that the case is blue and has the model number RC-04. Thus it is the case from Game Fire from the Silver series. But the metal front panel, the gameplay itself and the electronics are a Vermin MT-03. Probably the blue case was used in accordance to the term Blue from Blue Impulse.
