In the Gintama TV anime, Kouichi Yamadera plays Gintoki’s teacher, Shouyou Yoshida. And now, it looks like he’ll be reprising his role, but not for the anime adaptation. According to the official live-action Gintama Twitter Account, Yamadera will also be playing the character for the live-action film itself. They also revealed new still images of Yoshida with his students, including a young Gintoki, Katsura, and Takasugi of course.
Those who are familiar with Hideaki Sorachi’s manga, as well as its anime adaptations, know that Yoshida taught the trio. He founded the Shoka Sonjuku school, where Gintoki met Katsura and Takasugi. However, the Jouin War happened, and separated the trio.
