This is an original World War II era patch, likely associated with US Army Air Force (AAF) personnel who attended Japanese Language Schools. These distinctive patches were worn by interpreters, translators, and intelligence officers who specialized in Japanese language during the Pacific Theater operations. The patch features blue Japanese Kanji characters on a white background, encircled by red and a khaki border. It measures approximately 1.5 inches in diameter. The intricate embroidery and aged appearance confirm its authenticity as a period item. A valuable piece for any WWII militaria collector, especially those focusing on intelligence, language specialists, or the Pacific War.
