-suit actor doesn't actually planned to have as ichigo was actually acted by it's own actor even in rider form,but bcz some accident happened and fujioka hiroshi(actor of ichigo)was hospitalized and the whole program delayed, consider the risk of accident,then only the producer plan to recruit suit actor.

-almost all showa rider actor have knowledge in fighting skill :
ichigo(fujioka hiroshi) - karate,judo, some sword fighting skill and etc..
nigo(sasaki takeshi) -kickboxing
v3(miyauchi hiroshi) - karate
x(hayami ryou) - judo
skyrider(muragami hiroaki) - judo
stronger(araki shigeu) -judo
super-1(takasugi junsuke) - was an soldier in Japan Ground Self-Defense ForceJGSDF

-the first female rider :
stronger(Yuriko Misaki/Electro Wave Human Tackle),but because this character doens't fit in to declare as kamen rider,hence she was not the first female rider
agito(sawaki yukina,tsugami shouichi's sister),she only henshin into agito once,and was not a main line character,hence she was not the first female rider
ryuki(kirishima miho,kamen rider femme),the official first female rider in the whole kamen rider series..

-all heisei rider start from kuuga shown start from end of jan and start of feb..why?bcz creator of kamen rider,ishinomori was born around the date..

-decade's kuuga human name onodera was actually adapted from the creator real name(onodera shotaro)...
