This is a Japan national team uniform from Adidas. I believe I purchased it during the 2006 World Cup in Germany. The back is the type without a number, so anyone can wear it. I wore it a few times during Japan national team matches, but always inside my home. It has a design unique to Samurai Japan, inspired by Japanese swords, called "Hammon" (blade pattern) ^ ^ The size is Japan size M. #soccer #WorldCup #WorldCup Team/Group: National Teams Color: Blue
