Sadly missing from the archive is 1933’s Chikara to Onna no Yo no Naka (The World of Power and Women), the first Japanese-produced animation to feature voice acting.
The Japanese Animated Film Classics website is maintained by the National Museum of Modern Art in Tokyo.
Of special note is the inclusion of Junichi Kouchi’s The Dull Sword, the oldest surviving piece of Japanese animation (circa 1917).
