Nakagawa Accessories Chain This is an Ainu wooden carved amulet necklace. I believe it was a souvenir or something similar. It can be worn by both men and women. The close-up of the engraving looks rusty, but both the engraved plate and the chain are in beautiful condition. The third photo shows the actual condition. It's from a long-established manufacturer. For protection against bear attacks and other evils.
