But what if the two characters "meet" in a single setting?
Below is a video of that exactly happening--a rare footage of Segata Sanshiro actually "transforming" into Kamen Rider in a Japanese variety show in 1998.
He's also known for giving life to the unforgettable Sega Saturn mascot Segata Sanshiro in 1997. His character made such a huge impact that his commercials boosted the sales of the console. The birth of the Dreamcast then ultimately meant Segata's "demise" in his final TV commercial in 1998, but not before having a game named after himself, Segata Sanshiro Shinken Yugi, and making cameos in other Sega games. Fujioka reprises his role as the voice of Segata, who is also confirmed to be a playable character in the Nintendo 3DS game Project X Zone 2: Brave New World.
Fujioka is slated to play the role of Tadakatsu Honda in an upcoming taiga drama entitled Sanada Maru in 2016.
