Fictional scenario with questions related to remote work and short-term visas.

Hello! 👋

I need your thoughts about the following fictional scenario to confirm my assumptions. I omitted my assumptions here for brevity.

Scenario

• Emily is not a US taxpayer.
• Emily will be on a short-term visa to visit relatives.
• Emily will work in Japan during weekdays.
• Emily will tour Japan during weekends with her relatives.
• Emily will be working remotely for an employer outside Japan.
• Emily's employer pays her salary to her bank account outside Japan.
• Emily pays income taxes outside Japan.
• Emily's home country has a double tax treaty with Japan.

Questions

1. Is Emily's remote work arrangement legal?
2. Which taxes are required to be paid by Emily?
3. What happens if Emily has a bank account outside Japan and withdraws cash via an ATM in Japan?
4. What happens if Emily has a credit card issued outside Japan and used it in Japan?

Notes

1. I'm not a US taxpayer.
2. I'm not asking for professional advice.
3. Please do not provide professional advice.
