This is a Briobecca Urayasu uniform. Nike custom order, A44 tag. Size L. It is believed that the uniform used by the top team was demoted to the youth academy or used for training matches. The original number was 11, and the original sponsor has been covered with rubber adhesion. While I've often seen this type of uniform with Mizuno as a supplier, it's rare to see one from NIKE.
