Hello. I would like some help getting a little more information on a Japanese WW2-era sword. I've spent a few hours today looking around on my own, so here's a little back story and my ill-informed thoughts. My terminology will likely be no where correct, so my apologies
My great grandfather was a U.S. Senator and received a Japanese sword as a gift from Douglas MacArthur. I found the sword listed in an appraisal from the early '70s, but it didn't really give me any additional information besides confirmation on it's authenticity and mentioning a gold mark that signifies rank. I failed to find any information on that, but i'm thinking it may be the text included in the first picture (most of the other details on the hilt appear to be cherry blossoms, and are more of a bronze color, this is just speculation but possibly the text is in white gold?).
I have looked at a few low quality pictures of the hilt on "type 94" swords online and this seems to be more detailed, and couldn't quite match it with any other pictures. I can take high quality pictures tomorrow in proper lighting on a proper camera if requested.
Also: I attempted to cross match the text with the titles of the imperial army and navy (as given on wikipedia) but had no luck. I've read that swords were also given to U.S. servicemen and officers during Occupied Japan, so i'm speculating it may have been given to MacArthur or a subordinate after the war had ended.
edit: I'm working on uploading 3 additional photos, they're too large so i will need to edit them down first
edit 2: Also, because of it's sentimental value and historical significance (at least in my eyes) i will not be attempting to remove the hilt or any other pieces in any way shape or form, that'll be a professional/experts job, so I can not look for markings on the blade.
