This item was purchased in Germany a few years ago by someone I asked to go there. It has only been worn once and has been stored in a closet as part of a collection. I'm not sure about the Japanese size, but I've measured it with a tape measure and included photos for reference. There may be some minor thread fraying, but it's in relatively good condition. For those who collect items like this, and for those who understand that this is a used item stored at home, thank you in advance for your understanding.
