Actor Junichi Okada reveals home anatomy model during new bank ad launch

Junichi Okada appeared at a press conference in Tokyo on Jan. 31 for a new Mitsui Sumitomo Trust Bank commercial, co‑starring actress Fumino Kimura. During the event he talked about his personal interest in human anatomy, saying he owns a life‑size human model at home that he calls “Tanaka‑kun.” He explained that he is now focused on how tendons move the body, not just muscles, and hinted he may purchase a second model. Okada also highlighted his action‑film background and Brazilian jiu‑jitsu black‑belt as part of his physique training.

Both reports note his remarks about studying anatomy to better understand his own body and his desire to continue learning through such models.
