Aoshin was an older toy company with roots in Japan's post-war tin toy manufacturing. In the 1950's, Aoshin produced several classic tin robots (including the 'Tremendous Mike Robot' and the 'Chime Trooper') and a variety of model tin cars, all marked with their 'ASC' logo trademark.
Riding into the '70s, however, they found themselves face-to-face with a rapidly growing market for diecast toys instead.
