Yeah, me too. But I realized in about 2 seconds that getting walkable cities in the US within my lifetime is a pipe dream, so instead I just sold my car, packed my stuff, and moved to Tokyo instead.
Sorry, I don't have an email address posted here. Basically, it was pretty simple: look for job ads that fit my skills, and which didn't require Japanese fluency. There's a fair number of companies here hiring for such positions. Then I applied, did a video interview, and got hired. There's a bunch of job boards where you can find such ads: gaijinpot, tokyo-dev, japan-dev, linkedin, etc.
