The website celebrates the 100th anniversary of the oldest known Japanese animated short films, and is streaming the oldest surviving Japanese animated short film, Junichi Kouchi's "The Dull Sword" (Namakura Gatana, pictured below left). The film about a samurai's foolish purchase of a dull-edged sword debuted in June 1917. The version on the website is "the longest, digitally restored version," which is four minutes long.
The film was discovered in an Osaka antique shop in 2008, along with Seitarou Kitayama's 1918 film "Urashima Tarō." Several anime films directed by Oten Shimokawa and Kitayama predated "Namakura Gatana," but these films are now lost. Shimokawa's "Imokawa Mukuzo Genkanban no Maki" has long been considered the oldest commercially released anime film, having premiered in January 1917, but it may have premiered later that year, predated by two other films by Shimokawa. The films were all predated by a 50-frame shot of a sailor boy's salute that was discovered in 2005.The website is streaming 64 works that debuted from 1917 to 1941. Directors featured on the site include Ikuo Oishi, Shigeji Ogino, Hakuzan Kimura, Mitsuyo Seo, Yasuji Murata, Noburou Oofuji, Kenzo Masaoka, and Sanae Yamamoto.
