Young Brunette Girl With A Japanese Katana Sword Reveals In The Traditional Washitsu Room With Tatami Flooring

Description
The katana is generally defined as the standard size moderately curved (as opposed to the older "tachi" style featuring more curvature) Japanese sword with a blade length greater than 60 cm (23½ inches).
With a few exceptions katana and tachi can be distinguished from each other if signed, by the location of the signature (mei) on the tang (nakago). In general the mei should be carved into the side of the nakago that would face outward when the sword was worn. Since a tachi was worn cutting edge down and the katana was worn cutting edge up, the mei would be in opposite locations on the nakago of both types of swords.
