Yeah, it’d potentially be pretty cool. I kinda imagine what’d happen is that you’d end up with a very westernized city where most of the dev studios are, while the rest of Japan would likely continue to conform to current Japanese culture. Kinda like how I’ve heard Osaka is, but more weeb-y and less military grunt-y.

I imagine most westerners who’d immigrate would be more aware of Japanese culture though, so it might not cause as much of a culture clash as you might expect.
