Naniwa Danshi will perform the film’s theme song, and will also perform the long-time Nintama Rantaro anime series theme song “Yūki 100%” (Courage 100%), which will be used in the movie.
The 31st series in the Nintama Rantaro anime franchise debuted in April 2023.
The franchise’s previous film Gekijō-ban Anime Nintama Rantaro Ninjutsu Gakuen Zenin Shutsudō! no Dan opened in March 2011.
The manga inspired the Nintama Rantaro television anime in 1993, and the NHK-E channel is still airing the 10-minute anime every weekday.
