This is a humvent CPO jacket with padding. The outer fabric is a rough, almost coarse wool that gives it a vintage feel. It's a tightly woven wool that stands up on its own when placed on the floor. It should be more than warm enough for a winter in the Kanto region. Both the outer and lining have a very high-quality feel, so just throwing it on over denim or slacks will give you a great look. I wore it once for about two hours. Shoulder width: 49cm Sleeve length: 67cm Body width: 59cm Length: 80cm Regarding the padding, the only description is "functional padding," so I couldn't identify the specific material. I think it would fit well on someone 175cm or taller. Those who like brands like T.T, marka, auralee, and HEUGEN will likely appreciate this jacket.
