I think I remember writing about this before, but it's also unclear what comparative advantages a startup in Japan offers you outside of two things: easy access to the Japanese market if you think their consumers/businesses will be the largest market for your product, and world-leading expertise in robotics (and some other things). I guess you can also live in some huge, nice cities without absurd cost of living too. Not sure if those are worth all the operational and cultural difficulties for most people, relative to other places.
