Hi, I was sent here from the good people at bladeforums, as they told me this forum would be more knowledgeable on my situation. My grandpa left me his Japanese sword in his will. He got it while he was stationed in Japan after US occupation. He was allowed to take home a sword and a pistol from the confiscated weapons there. I removed the handle and found no markings on the tang. Any info would be much appreciated. I found that the sash is written in old Chinese and roughly translates to "Go this way to end your bloodline." Lol
