It was released in Japan on March 16, 1985, alongside Gu-Gu Ganmo, Dengeki Sentai Changeman, and Tongari Boushi no Memoru.
This film is the first to feature anime original character Kinkotsu-Obaba.
This is also the second time voice actor Ichirō Nagai appears in a Kinnikuman work playing the main villain.
It also features the return of voice actors Kōzō Shioya and Yasuo Tanaka, who had previously appeared in the first film Stolen Championship Belt.
While Kinnikuman is on vacation with Mari-san's kindergarten class at Easter Island, the young Kouichi-kun, who uses a wheelchair, laments being with Kinnikuman, preferring to instead be with his favorite Justice Choujin Buffaloman.
