The Dull Sword

is a Japanese animated short film produced by Jun'ichi Kōuchi in 1917. It was rediscovered by an antique shop employee in Osaka in March 2008. This film is a 4-minute silent short that tells a story about a foolish rōnin's purchase of a dull-edged sword and subsequent attempts at tsujigiri. It was released on June 30, 1917, and is among the very earliest examples of anime.

Plot
Namakura Gatana (lit. 'dull-edged sword'; gatana is rendaku of katana) is a short comedic jidaigeki about a dim-witted self-appointed samurai and his worn-down sword which turns completely useless as he tries to fight even the weakest opponents. The samurai, trying to figure out why his old sword cannot cut anyone he strikes, tries desperately to attack random townspeople who defend themselves and knock him out.
