Thank you all for the help! Yes, the habaki pic was from the other sword (the Chinese fake). Sorry for the confusion! I'm not quite certain what I am going to do with this one.
I just acquired a couple of Japanese swords and need some help. This ricasso has the Tokyo arsenal mark (with serial number) on one side and lettering on the other side that needs translation. The backstrap has the traditional Cherry Blossom accents but also has a pair of flags. The other sword I will show in a separate post. Thank you for any help you can give!
