CheapyD, you should really talk to other parents about what their children watch. You've been living in Japan so long and I'm surprised that you didn't know that Super Sentai (Power Rangers) is a big thing in Japan like Ultraman or Kamen Rider. Depending on when Saban gets around to it, you'll see it in Power Rangers form in the next few years, though Tai will have outgrown them by them.
Here's a simple enough article, by another parent living in Japan:

Besides, I'm pretty sure the "Go Busters" air at 7:30 on a Sunday morning, too early for adults, but the right time for children.
Oh right, Wombat here's a video about some live action Turtles.
