Masudaya, also known as Masudaya Modern Toys, is a Japanese toy maker which became known as a leading builder of mechanical and battery operated toys in the post WWII era. Unlike most of their competitors, this company has managed to survive to this day, in part due to their involvement in the early days of the airsoft boom, during the early 1980s. The company was known for essentially creating the "skirmishable" airsoft gun. They were the first to design airsoft guns to be used for combat simulation. Before that, all airsoft guns were essentially for target shooting in your backyard.
