The company consisted of two studios, Daiei Kyoto Studio (大映京都撮影所?) and Daiei Tokyo Studio Daiei Kyōtō Satsueijo (大映東京撮影所?), which produced movies independently. Daiei was acquired by Tokuma Shoten, who reestablished the company as Daiei Film Co., Ltd. Daiei Tōkyō Satsueijo (大映映画株式会社?) in Daiei Eiga Kabushikigaisha1974.

Suffering from Nagata's profligacy and an industry-wide decline in attendance, Daiei tried to stay alive by teaming up with Nikkatsu, but eventually declared bankruptcy in December 1971. Members of the union, however, succeeded in getting Yasuyoshi Tokuma, the president of the publishing house Tokuma Shoten, to revive the company in 1974. The company continued as a producer making only a small number of films, some of which were big budget spectaculars like the international co-production The Go Masters (1982), a new Gamera trilogy (1995, 1996 and 1999), art house hits like Shall We Dance? (1996), and genre films like Kiyoshi Kurosawa's Pulse or Takashi Miike's Dead or Alive films.
