アントニオ猪木 - A famous sumo wrestler before entering politics as very colorful politican. Was in FPG for a while before joining AEJ. He was the lone dove in FPG and was close to the DPRK regime. He only joined FPG because of his relationship with Ishihara Senior. Once Ishihara retired he also split from FPG when his politics does not match FPG. Most likely to be against Constitutional change.
Antonio Inoki is not a sumo wrestler! He's one of the most famous professional wrestlers ever (invented the Enziguri, wrestled for 4 decades, wrestled almost every wrestler in existance, basically invented MMA, once fought Mohammed Ali, etc.). Kind of like Japan's Hulk Hogan equivalent.
If you saw a picture of him, you'd know he was never a sumo wrestler (far too skinny).
