備後三次住田村正行 on page 560 of Toko Soran (刀工総覧)

Ref.

I think that Jan’s reading “備後三次住田村正行作 = Bingo Miyoshi-jū Tamura Masayuki saku” is correct.

Under normal circumstances, all nihonto in Japan had to be banned and scrapped just after WWII, because they were thought to be mere arms. To save their lives, nihonto were defined as artwork and traditional crafts to be preserved. Therefore, existing nihonto must be traditionally made from traditional material and registered as artwork. Any blades like nihonto which do not clear the criteria to be registered are thought to be only weapons and illegal in Japan. IMHO, modern nihonto are not expected or allowed to be improved as weapons beyond traditional borders.

The blade is a wakizashi. Anyway, it is still a give away.

I am sorry. That is my careless mistake. Showa 20 year (1945) is correct.
