According to Natsuki Matsumoto, the first animated film produced in Japan may have stemmed from as early as 1907. Known as , from its depiction of a boy in a sailor suit drawing the characters for "katsudō shashin", the film was first found in 2005. It consists of fifty frames stencilled directly onto a strip of celluloid. This claim has not been verified though and predates the first known showing of animated films in Japan. The date and first film publicly displayed is another source of contention: while no Japanese-produced animation is definitively known to date before 1917, the possibility exists that other films entered Japan and that no known records have surfaced to prove a showing prior to 1912. Film titles have surfaced over the years, but none have been proven to predate this year. The first foreign animation is known to have been found in Japan in 1910, but it is not clear if the film was ever shown in a cinema or publicly displayed at all. Yasushi Watanabe found a film known as in the records of the company. The description matches James Blackton's "Humorous Phases of Funny Faces", though academic consensus on whether or not this is a true animated film is disputed. According to Kyokko Yoshiyama, the first animated film called was shown in Japan at the in Tokyo sometime in 1911. However, Yoshiyama did not refer to the film as "animation.” The first confirmed animated film shown in Japan was "Les Exploits de Feu Follet" by Émile Cohl on April 15, 1912. While speculation and other "trick films" have been found in Japan, it is the first recorded account of a public showing of a two-dimensional animated film in Japanese cinema. During this time, German animations marketed for home release were distributed in Japan. In 1914, U.S. and European cartoons were introduced to Japan, inspiring Japanese creators like Junichi Kouchi and Seitaro Kitayama, both of whom were considered the "fathers of anime."
