mastermind JAPAN has always insisted on pure dark street style, and it is difficult to see other styles appearing in co-branding with many brands. This also allows it to have absolutely loyal consumers, which can be called a myth in the fashion circle. After announcing its demise in 2013, mastermind JAPAN has continued to return to the trend circle in the form of joint brands, but it seems to have lost its former popularity. Recently, dark street brand mastermind JAPAN and Converse have joined forces to launch a new joint shoe model based on the classic open smile.
