Issues and Concerns on Full-Time Remote Work for Foreign Company Outside Japan as Independent Contractor while Living in Japan on existing Working Visa

I got unemployed last year. However, my work visa(Engineer/Specialist in Humanities/International Service) is still valid for the next 3 years. Now, I’m considering a full-time remote work for a foreign company outside Japan as Independent Contractor.

  1. Is this ground for revocation of my residence status?
  2. For income tax filing as freelancer, below are the required documents as mentioned in this blog. I have scratched out the items that I can easily obtain except for one.
  • Japanese residence card (zairyū kādo 在留カード)
  • My Number information
  • Tax withholding slips from each company you work(ed) for For full-time workers, it’s called gensenchoshuhyou 源泉徴収票. For freelancers, it’s called shiharai chōsho 支払調書.
  • Any other documents given to you by the companies you work for
  • Receipts for all deductibles This is broad and can include all expenses related to your work. For example, if you work from home, you can deduct your rent and utility bills.
  • Your banking information and/or bank book You might need to either make a payment – or receive one, if you’re lucky.

How will I obtain a shiharai chōsho 支払調書? Since I'm not working for a Japanese company, what is the alternative requirement for this?

 3. How can I renew my work visa(Engineer/Specialist in Humanities/International Service) on this type of work arrangement? My home country is not eligible for Digital Nomad Visa at the moment.
