We should wait for some of the members who know much more about these but in the meantime, until they show up I'll piggy back off of Avenger here.
Check this website out. Should give you a bit more color. The sword while different in some minor aspects (mainly engraving of the handle), is identified as a WWII Japanese Army Officer parade sword issued to officers in the Police department. I would assume that the police were part of the military? Either way, nice sword that appears to be in nice condition.
