This is a mod coat, likely an M65, purchased in Shimokitazawa. It has been dry cleaned, but being vintage, it has some old clothing smell and a used feel, but it's a piece with a lot of character. The size fits a 164cm tall man perfectly, so it's likely a size M. *The zipper pull is missing (see image 4), but the buttons can be used to achieve the same function as the zipper.
