Seeking Advice on Japanese Tax as a Foreigner Moving to Japan

Hey everyone,

I'm reaching out to anyone who's lived in Japan as a foreigner and might be able to share some insights on Japanese tax, especially as it relates to my family's situation.

I'm Australian, married to a Japanese citizen, and we're considering moving to Japan for a year or two. We're also thinking about applying for Japanese permanent residency (PR) for me and sending our son to kindergarten there. However, I'm concerned about the tax situation in Japan, especially since I've heard it's quite high.

Recently, I inherited a significant sum of money (say 500K USD) from my father who passed away, and I'd like some clarity on a few things:

1. Will bringing this money into Japan to buy an Akiya (an abandoned house) and live off my savings trigger any taxable event? Are there any ways to minimize tax in this case?
2. Does Japanese inheritance or gift tax apply to me or my Japanese wife in this scenario?
3. Given my situation, would I be considered a resident for tax purposes once we move?

I'd really appreciate any advice or experiences you can share! Thanks in advance!
