This is an Adidas bench coat. I'm not sure about the Japanese size, but online it was listed as M. Please check the size in the third picture. There is a small stain on the sleeve, so I've lowered the price for the final sale. Please refrain from purchasing if you are sensitive to details, as I am a private seller. I will use simple packaging and recycled materials. *I will offer a small discount if you purchase multiple items. Please take a look at the items I have for sale in my profile and comment if you would like to purchase multiple items m(_ _)m
