Question Japanese sword
Hello all, I have not posted on here since forever, but have been reading all the great information about all the collections, finds, and other fantastic topics. Long story short, a coworker brought me a Japanese sword and asked if I could find information about it. Does any one have a go to person I could contact that I could get in touch with about this sword? I see no military markings on it, and cannot see if it is signed, but it came home from a person who worked at radio Tokyo during occupied Japan. He also brought home different propaganda leaflets the Japanese had passed out. Any help would be greatly appreciated. Thanks!
