Sound film
The primary steps in the commercialization of sound cinema were taken in the mid- to late 1920s. At first, the sound films which included synchronized dialogue, known as "talking pictures", or "talkies", were exclusively shorts. The earliest feature-length movies with recorded sound included only music and effects. The first feature film originally presented as a talkie was "The Jazz Singer", released in October 1927. A major hit, it was made with Vitaphone, which was at the time the leading brand of sound-on-disc technology. Sound-on-film, however, would soon become the standard for talking pictures.
Sound film
During the 1920s and 1930s, Japan was one of the world's two largest producers of motion pictures, along with the United States. Though the country's film industry was among the first to produce both sound and talking features, the full changeover to sound proceeded much more slowly than in the West. It appears that the first Japanese sound film, "Reimai" ("Dawn"), was made in 1926 with the De Forest Phonofilm system. Using the sound-on-disc Minatoki system, the leading Nikkatsu studio produced a pair of talkies in 1929: "Taii no musume" ("The Captain's Daughter") and "Furusato" ("Hometown"), the latter directed by Kenji Mizoguchi. The rival Shochiku studio began the successful production of sound-on-film talkies in 1931 using a variable-density process called Tsuchibashi. Two years later, however, more than 80 percent of movies made in the country were still silents. Two of the country's leading directors, Mikio Naruse and Yasujirō Ozu, did not make their first sound films until 1935 and 1936, respectively. As late as 1938, over a third of all movies produced in Japan were shot without dialogue.
