Well, just a passing mention of new Japanese heroes there, I'm sure I read him talking about it in more detail somewhere.
IT seems unlikely, but it's possible, right? I mean, Japan has its own culture of superheroes, so if there are metahumans around and amazing technology then surely some will have taken up Kamen Rider-esque mantles? Maybe someone with the power to grow in size mimicing an Ultraman costume, a non-meta equivalent of Batman or Ironman in a toku-style suit, or someone with super strength and agility like Kamen Rider the First. It'd be a great injustice if they did not acknowledge it, and I'm sure there have been some references, homages, parodies and even rip offs in the past, but it doesn't seem fair if all they have is a bunch of superpowered sumo wrestlers and narutards.
