Taxes Due for U.S. Remote Work in Japan [Unrestricted Visa]

Hi there. I just had a question about how to deal with the taxes between Japan and the US for the following scenario:

  • I will have an unrestricted work visa and expect to pay taxes on my salary in Japan like everyone else.
  • Because of my unrestricted work visa, I will keep my remote job that I have in the US and they are aware I am living in Japan.
  • I will also declare my US income with the Japanese government, and will use FEIE for taxes back home
  • My spouse (also American) will accompany me to Japan and they also work remotely, but they will not work for a Japanese company.
  • I plan to use the HSP points system to get PR after 1 year

With these in mind, I wanted to ask the following questions:

  • Will I owe taxes on my Japanese and remote work income combined, or will my US income be handled differently in Japan?
  • Will I owe state taxes in the US after FEIE is applied, or are there credits/allowances that could clear me?
  • Will my spouse also need to declare their income under their status? Or is Japan not interested in them since I'm the worker?
  • How does this affect getting PR using the HSP points system?
    • Do I get to say my total income is my JP + US salary combined?

Lastly, a bonus question

  • If I leave my company after getting PR, will it be possible to operate in Japan purely off my remote income as far as taxes go? Or will I need to operate as something like an independent contractor for tax purposes?
