film studio. Kenzō Masaoka, another important animator, worked at a smaller animation studio. Many early animated Japanese films were lost after the 1923 Tokyo earthquake, including destroying most of the Kitayama studio, with artists trying to incorporate traditional motifs and stories into a new form. Prewar animators faced several difficulties. First, they had to compete with foreign producers such as Disney, which were influential on both audiences and producers. Foreign films had already made a profit abroad, and could be undersold in the Japanese market, priced lower than what domestic producers needed to break even. Japanese animators thus had to work cheaply, in small companies with only a handful of employees, which then made it difficult to compete in terms of quality with foreign product that was in color, with sound, and promoted by much bigger companies. Until the mid-1930s, Japanese animation generally used cutout animation instead of cel animation because the celluloid was too expensive. This resulted in animation that could seem derivative, flat (since motion forward and backward was difficult) and without detail. But just as postwar Japanese animators were able to turn limited animation into a plus, so masters such as Yasuji Murata and Noburō Ōfuji were able to perform wonders that they made with cutout animation. Animators such as Kenzo Masaoka and Mitsuyo Seo, however, did attempt to bring Japanese animation up to the level of foreign work by introducing cel animation, sound, and technology such as the multiplane camera. Masaoka created the first talkie anime, Chikara to Onna no Yo no Naka, released in 1933, and the first anime made entirely using cel animation, The Dance of the Chagamas (1934). Seo was the first to use the multiplane camera in Ari-chan in 1941. Such innovations, however, were difficult to support purely commercially, so prewar animation depended considerably on sponsorship, as animators often concentrated on making PR films for companies, educational films for the government, and eventually works of propaganda for the military. During this time, censorship and school regulations discouraged film-viewing by children, so anime that could possess educational value was supported and encouraged by the Monbusho (the Ministry of Education). This proved important for producers that had experienced obstacles releasing their work in regular theatres. Animation had found a place in scholastic, political, and industrial use. During the Second World War In the 1930s, the Japanese government began enforcing cultural nationalism. This also lead
