Netflix’s Japanese ‘Gas Human’ reboot fuels buzz with striking cast transformations

The Netflix series “Gas Human”, a reboot of Toho’s 1960 special‑effects film, has generated strong social‑media reaction for the dramatic physical changes of its cast. Actor Kobayashi Motoki, who plays detective Yoshida Norio, lost about 17 kg, adopted a breath‑less speech pattern, and cut his cheekbones to portray a morally compromised officer, crediting a recommendation from co‑star Shun Oguri for landing the role.

Veteran star Takeuchi Yutaka appears as the present‑day villain Mori Yasuto, undergoing extensive prosthetic work, a shaved head, and a drastic hairstyle, while younger actor Shun Nomura portrays Mori’s past self. Viewers noted the uncanny similarity between the two performances, with many only realizing the transformation after watching. Netflix Japan highlighted side‑by‑side images of the actors, adding to the series’ visibility. The show, produced by Toho in partnership with Netflix, continues to draw attention for its ambitious makeup, weight‑loss commitments, and the actors’ dedication to the reboot.
