Work remotely for a foreign company while in Japan

Hi everyone,

I’ve looked into this but haven’t found much information, so I’m reaching out here.

I currently live in Australia and will be moving to Japan next year with my Japanese wife. I’ll be on a spouse visa that allows me to work full-time, so the visa isn’t an issue. We plan to live in Japan permanently.

My employer in Australia has offered me the option to work remotely from Japan. As the first employee to do this, they’re uncertain about the logistics, and I am as well.

Could anyone clarify the bureaucratic process for this situation? Specifically, will I need to pay taxes in Japan or Australia? What steps should I and my employer take so that I can work from Japan legally?

If anyone could help me understanding at least the basic of this, I would be really grateful.

Thank you for your help!
