Ōgon Bat (Japanese: 黄金 バット, Hepburn: Ōgon Batto, lit. "Golden Bat") is a Japanese superhero created by Takeo Nagamatsu in 1931. Ōgon Bat is considered to be the first Japanese superhero. Originally debuting in kamishibai (paper theater), Ogon Bat is considered a precursor to later superhero characters such as the Japanese Kamishibai character Prince of Gamma (debuted early 1930s) and the American comic book characters Superman (debuted 1938) and Batman (debuted 1939).
