Congratulations on taking the dive! I've met lots of digital nomads and starry eyed entrepreneurs in Japan but the slog and paperwork of getting things set up often puts them off.
Let me know if you make it to Fukuoka and I'll buy you a coffee.
Do you have a blog? I am currently in Australia, and actually becoming a digital nomad is a kind of dream of mine. Not really sure how to make it a reality though...it seems that webdev/online contracting is such a saturated and race to the bottom pool.
I have a blog when I have the time to update it - rarely. I'm looking to hire developers, so if you don't mind being a remote employee we should talk. Google my HN username and you should find me easily enough.
Already got a small team of contractors here. Currently working through the paperwork to get my visa and company incorporation sorted here.
P.S. Situation is still notable in its normalcy.
