Your title is correct. This is a Japanese bone tourist tachi (sword made
to be worn edge down by strapping). The blades are normally not folded,
not laminated and untempered. Most made between the late Meiji Period until WW II. The value is as a tourist item, quality of carving and as a family momento.
