Did the first power rangers start in japan?

Answer 1

There is no museum that is just for Power Rangers or its Japanese counterpart known as Sentai in Japan however Japan does have the Bandai Museum. The Bandai Museum holds various things from various Sentai series such as the Mecha suits which would be known as zord suits in Power Rangers terminology. The Bandai Museum also keeps old models that the Sentai once used such as the models that were used for Power Rangers' Mastodon, Pterodactyl, Triceratops and Saber-Toothed Tiger Dinozords from the first season of Mighty Morphin Power Rangers Season 1.

Answer 2

Yes, Power Rangers did start in Japan in 1975 however it was called a Sentai series back then however it was considered a Super Sentai series once they made and aired Battle Fever J in 1979. The first season of Mighty Morphin Power Rangers was adapted from Sentai's 16th series which was called Zyuranger and began airing in Japan in 1992.
