๐ฏ๐ต Retiring in Japan? Your IRA and 401(k) Might Work Better Than You Think
If you're an American living in (or considering a move to) Japan, understanding how your U.S. retirement accounts get taxed there is critical โ and the news is better than most expats assume.

Even better, distributions often qualify for generous Japanese deductions (like the public pension deduction or a 50% retirement income deduction) that can meaningfully soften your tax bill.
There are wrinkles, though โ especially for Roth IRAs, which lose their tax-free status in Japan's eyes. ๐งฉ
