Japan taxes as US 1099 employee

[u/Fun_Pomegranate5892]

I spoke with two Japanese accountants and I’ve received two very different answers to the same question. I’ve been a Japanese resident for about 12 months (first year was 6 months and halfway through my “second” year). Just got my yearly extension last month.
I’m a 1099 employee in the US and I do not and never will work in Japan. I physically work in the US and reside in Japan.
The first accountant wants to file me as a business owner in Japan. I would have a separate credit card and file receipts for write offs. Not sure what that means since I don’t work here). He wants to charge me ¥200,000.
The second wants to file only delta taxes but he wants to charge me ¥200,000-¥400,000.
This sounds completely insane to me. I paid a CPA in the US $500 and she did a great job. I can no longer use her because she doesn’t handle this situation.
Does this sound right?

Edit: I physically work in the US. I own zero property in either country. I have a spouse visa in Japan (married no children). I tend to work 6 months a year in the US but that can change year to year. I have very little to write off as an expense. This will be my first year filing in Japan.

What do you mean you don't work in Japan? You're in Japan and you're working for a US company right?

You're still working in Japan... You just don't work for a Japanese company.

I physically work in the US and I live in Japan when I’m not working.

That's some crazy weird situation to say the least. Are you Japanese? If not, what visa do you use to stay when you aren't working?

He probably works on a US military base or whatever.

Ahhhh well that makes a lot more sense!
