I apologize if this is not permitted here, I tried asking in r/japanfinance and ended up getting trolled by 1 guy.
I was sure I read this somewhere in Japanese where it said that whether you're a tax resident or not depends on your domicile which is based on a number of factors.
Because if it was based on Juminhyo then wouldn't non-permanent tax resident people just evade taxes by filing moving out notifications, selling assets overseas and coming back to Japan after to avoid taxes on those income?
