Seiji Takaiwa (高岩 成二, Takaiwa Seiji) is a Japanese actor and stuntman better known as the suit actor for 18 of the 20 lead Heisei-Era Kamen Riders (excluding Kuuga and Hibiki, although his role as Decade allowed him to wear the suits). In 2019, beginning with Zero-One, he stepped down as lead suit actor and suit-acted as Horobi instead, with it being his most recent role.


When Takaiwa was in middle school, he knew he wanted to have some sort of athletic career and set his eyes on either being a stuntman or a physical education teacher. He was inspired to pick the former by Hiroyuki Sanada and enrolled in Japan Action Club (now known as Japan Action Enterprise) in their gymnastics program. Since graduating, he has been the suit actor for many Tokusatsu heroes.

In 2021, Takaiwa announced the expiration of his contract with JAE and would continue as a freelancer. [2]

Personal Life

  • He is married to retired stunt performer and suit actor Rie Murakami. Their son is Shinta Takaiwa.


Stunt/Suit Actor Roles

Non-suit Actor Roles


  • Because of his role as the suit-actor for the main primary Heisei Riders, fans have given him the nicknames: "Mr. Kamen Rider" (ミスター仮面ライダー, Misutā Kamen Raidā) and "Mr. Heisei Rider" (ミスター平成ライダー, Misutā Heisei Raidā).
  • In 2022, Takaiwa had a starring role in Good Morning, Sleeping Lion. The show also guest starred Takayuki Tsubaki from Blade, Masahiro Inoue from Decade, Shun Nishime from Ghost, and Gaku Sano from Gaim, all who stated they decided to appear in the show to support Takaiwa as he suit acted for each of them.[3]
