Sato played Takechi Henpeita in the first film, but teased that he will play a different role in the sequel.
A stage presentation at the Jump Festa 2018 event on Sunday revealed that actor Jiro Sato will appear in the tentatively titled Gintama Part 2 live-action sequel film.
The first film opened in Japan on July 14, and it earned 980 million yen (US$8.9 million) in its first four days.
The film also inspired a live-action net show that debuted on Docomo’s dTV streaming service on July 15, one day after the film’s opening.
