This is a reversible nylon parka from the 80s. It has a short length and wide width, giving it a trendy boxy silhouette. The details, such as the weight of the hood string tips and the zipper, are simple yet well-crafted vintage. I bought it at the vintage clothing store Lemon Tea for 16,000 yen. If you'd like to know the size, please comment!! Thank you for looking.
