I bought this about 40 years ago at Nakata Shoten in Ueno Ameyoko for around 100,000 yen. I haven't worn it much in the last 30 years, and it's been stored in a closet. The size is marked as 38, and it fits me, who is 172cm tall and weighs 68kg, perfectly or perhaps a little large. There is a repair on a tear in the shoulder area, so I'm selling it as junk. No claims or returns accepted.
