BEAMS JAPAN created this special-order 2-way bag from a mold made by Tanei Corporation of Toyokawa City, Aichi Prefecture, which has a history of over 100 years in the manufacture and sale of judo uniforms, using fabric from judo uniforms and a black belt. By changing the D-tube through which the black belt (shoulder strap) is threaded, the bag can be used as either a one-shoulder bag or a backpack. The black belt is tightened at the top of the main body and placed on the shoulder, just like the judo technique of Ippon backpack! The black belt is a special specification with a gold thread tag, which is no longer used. You can enjoy the aging process of the dogi and black belt as you use the item.
