I wrote WWII M-41 field jacket in the title, but the official name is unknown because it doesn't have shoulder epaulets. When listing, I researched online and asked questions to the owner of a military shop, but I couldn't get any useful information. I acquired it in the early Heisei era, purchased from a military shop in Zoshiki, Ota-ku, Tokyo. I have owned it for over 35 years. The condition is excellent, with only a little fading around the collar. As mentioned in the special notes, there are small holes in the lining. There is no damage to the cuffs or hem, which is common. Please refer to the attached images. The size is such that it feels tight around the stomach and the fingers are visible from the sleeves when worn by a slightly chubby person who is 164cm tall and weighs 82kg. It's probably a Japanese size L. I apologize for this when listing, but if anyone has information or knowledge about this jacket, I would appreciate it if you could write it in the comments. Rather than enjoying wearing it, it might be more of a collector's item given its condition. To put it dramatically, I would be happy if someone who understands its historical value could own it. The listing price is far below the purchase price. Since the official name (model) is unknown, if anyone has any information, please let me know in the comments.
