Rare WWII Japanese Bukosho Medal

Rare WWII Japanese Military Service Badge. This is one of the highest Army badges, prized mainly for its scarcity but also because it was awarded for distinguished military valor. It was established in December 1944 in two classes. Both badges were made of iron. The 1st Class with gold edges is called Kou in Japanese and the 2nd Class Otsu. This is the 2nd Class badge, in excellent condition, 40mm X 50mm.
