Speaking of Toei, I think we are again ignoring the fact that they are not the only company that has a stake in their shows. The rights to Kamen Rider are divided between them, Ishinomori Production and TV Asahi (+ TTFC rights to exclusive screening of various specials). And Bandai is also unlikely to remain silent. With Sentai, everything is even simpler: the world is divided between them and the Power Rangers, and you can climb into someone else’s territory only after many years and exclusively on DVD. Therefore, bringing its most successful franchises to the West is very problematic for Toei. And Zubat is unlikely to win the hearts of modern children
Also, given all the unboxings of tokusatsu toys I've seen, for some reason it seems to me that Toei receives a percentage for them from companies involved in transporting Japanese goods abroad. Maybe not from everyone, but from the largest ones for sure. This means that there are still several legal entities that are not interested in Toei entering the international market.
So the only way I see Toei really going to conquer the West is if they buy the rights to Power Rangers. But, unfortunately, this is too unlikely.
