Seiji Takaiwa (高岩 成二, Takaiwa Seiji) is a Japanese actor and stuntman better known as the suit actor for 18/20 of the lead Heisei-Era Kamen Riders (excluding Kuuga and Hibiki, although his role as Decade allowed him to wear the suits). Since the beginning of the Reiwa-Era, Takaiwa has passed on the lead suit acting to Yuya Nawata, while taking on in-suit portrayals of other non-lead Riders.


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 Acting Club (now known as Japan Acting Enterprise) in their gymnastics program. Since graduating, he has been the suit actor for many Tokusatsu heroes.

Personal Life

He is married to retired stunt performer and suit actor Rie Murakami, and is the father of Shinta Takaiwa.
