I can't speak much about medals but Tadao Nakata has been making quality repros for many years. When I was collecting Japanese, his items were very difficult to obtain in the states as he wouldn't ship unless it was a very large quantity order. At various times I have owned Cherry Blossom helmets, NLF Para helmets and entrenching tools by Nakata and all were marked as being reproductions. I found when doing displays that the problem with the markings were that they were in Japanese (go figure), this led many to believe that they were in fact Japanese items from WWII... If he is the producer of the medals, I am sure that they would be marked or altered for identification. In the 70s he made a few impeccable Japanese Army Para helmets, I owned one of these and the story was that they were made from real parts. I could find nothing on this helmet to clearly say that it was a repro, until I finally got a real one. the only difference aside from patina, was that the real one had a magnetic shell and the repro did not.... Scary but true, Nakata is a master among Japanese collectors:ninja: . Scott.
