In 1918, the craftsman M. Hayakawa Juichi settles in the Osaka region with its jukendo (bayonet) equipment factory. After years of sharp decline in the number of martial artists at the beginning of the Meiji era (Japanese Industrial Revolution), the number of practitioners begins to rise and Judo becomes popular. With his experience in the Sashiko (rice grain) fabric, Mr. Hayakawa focuses on the manufacture of Judogi.
During the US occupation that follows World War II, the martial arts are prohibited and it is only at the lifting of the ban that the Japanese government undertakes to “renew” the image of the traditional martial arts. Judo, which was developed as a method of education by its founder, is heavily promoted, leading to a significant increase in the number of practitioners, until it becomes the second Japanese martial art behind Kendo.
