If you’ve been in Japan long enough to receive that year-two resident tax bill, you’ve probably also heard people mention ふるさと納税 (furusato nozei). The system lets you redirect a portion of what you’d pay in resident tax anyway — to towns and cities around Japan — and receive regional food and goods in return, with your net out-of-pocket cost capped at ¥2,000 for the year.
Foreign residents are fully eligible. The only requirement that matters is whether you pay Japanese income tax (所得税 / shotokuzei) and/or resident tax (住民税 / juminzei). If you do, furusato nozei is available to you, regardless of nationality or visa type.
What Furusato Nozei Actually Is
The name translates roughly as “hometown tax,” but it is not a tax — it is a donation (寄附 / kifu) to a local government. You choose a municipality, donate online, and that municipality sends you a thank-you gift (返礼品 / henreihin): Wagyu beef, Hokkaido seafood, Okinawa fruit, sake, whatever the region produces. By national rule, the gift value is capped at 30% of your donation.
The tax benefit is separate from the gift. The amount you donate above ¥2,000 is returned to you through a combination of income-tax deduction and a reduction in your following year’s resident tax. So if you donate ¥50,000 across multiple municipalities and stay within your personal limit, roughly ¥48,000 comes back to you through lower taxes — your true cost is ¥2,000, and you keep the gifts on top.
That ¥2,000 is a fixed cost regardless of how much you donate within your limit. Donate ¥30,000 or ¥150,000, the net cost stays ¥2,000.
Yes, Foreigners Are Eligible
The Ministry of Internal Affairs (Soumu) defines eligibility by tax obligation, not nationality. Work visa holders, permanent residents, and long-term residents who are paying Japanese income tax or resident tax can participate on exactly the same terms as Japanese nationals.
The practical entry point is your resident tax, which shows up as 住民税 (juminzei) on your Japanese payslip. If you’re a full-time employee and you’ve been in Japan for over a year, you’re almost certainly paying it already.
How Much Can You Donate? Your Limit
Your personal donation limit exists because of how the deduction is structured — specifically, the 20% cap on the “special resident-tax deduction” portion (explained in the next section). Donations above your limit are not deducted: you receive the gift, but the excess tax benefit disappears.
The official Soumu reference figures below assume a single person or dual-income couple with no dependents and no other major deductions. If you have dependents, a mortgage deduction, or large medical deductions, your real limit will be lower. Use these as a starting estimate only.
| Annual salary income | Approximate donation limit |
|---|---|
| ¥3,000,000 | ~¥28,000 |
| ¥4,000,000 | ~¥42,000 |
| ¥5,000,000 | ~¥61,000 |
| ¥6,000,000 | ~¥77,000 |
| ¥7,000,000 | ~¥108,000 |
| ¥8,000,000 | ~¥130,000 |
| ¥10,000,000 | ~¥180,000 |
For your actual number, use the official Soumu simulation tool or the simulator built into most furusato nozei portals. The portal simulators are generally accurate, but treat the result as a ceiling, not a target.
How the Deduction Works
The deduction comes in three parts, applied across income tax and resident tax:
(a) Income-tax deduction
(total donations − ¥2,000) × your marginal income-tax rate
This typically comes back as a refund when you file your tax return, or adjusts your year-end withholding.
(b) Basic resident-tax deduction
(total donations − ¥2,000) × 10%
Applied to the following year’s resident tax bill.
(c) Special resident-tax deduction
The remainder — whatever wasn’t covered by (a) and (b) — reduces your resident tax further. This is capped at 20% of your resident-tax income portion (所得割 / shotokuwari). The 20% cap is what creates your personal limit. If you donate beyond your limit, part (c) maxes out and the rest of the donation is not deducted. You still get the gift, but you’ve paid for it at full price.
Two Ways to Claim: One-Stop vs Tax Return
Once you’ve made your donations, you have two options for claiming the deduction. Which one applies to you depends on whether you file a tax return for any other reason.
One-stop exception (ワンストップ特例 / one-stop tokurei) | Tax return (確定申告 / kakutei shinkoku) | |
|---|---|---|
| Who can use it | Salaried employees who do NOT otherwise file a tax return | Anyone; required if you file for any other reason |
| Municipality limit | 5 or fewer different municipalities in the year | No limit |
| How to claim | Send application form to each municipality | List all donations on your tax return |
| Deadline | Forms must arrive by January 10 of the following year | Standard tax return deadline (March 15) |
| Result | Entire deduction comes off resident tax only | Part refunded via income tax, rest off resident tax |
| My Number required | Yes — card copy or notification card + photo ID | Yes — standard tax return requirement |
One-stop specifics: You submit a separate application form to each municipality where you donated. Multiple donations to the same municipality count as one. If you donated to five municipalities, you send five forms. The deadline is arrival by January 10 — postmarked is not enough. Many portals now support online one-stop submission via the My Number Card smartphone app, which avoids the mail deadline risk.
Tax return: You report all donations as charitable contributions on your 確定申告. The income-tax portion of the deduction comes back as a refund; the rest reduces your resident tax the following June.
The Trap for Engineers Who File a Tax Return
This is the scenario that catches the most foreign engineers. You donate to a few municipalities in November, file one-stop applications in December, and then in February you remember that you have family overseas you can claim as dependents — so you file a 確定申告 to get the overseas dependent deduction (扶養控除 / fuyou kojo).
The moment you file that return, every one-stop application you submitted is voided. The municipalities will not alert you. If you don’t re-add all your furusato nozei donations to that return, you receive no furusato nozei deduction at all.
The fix is straightforward once you know the rule: if there is any chance you will file a tax return, skip one-stop entirely. Collect your donation receipts (each portal or municipality provides them), and declare everything through your 確定申告. You get the same tax benefit; it just comes partly as an income-tax refund rather than entirely as resident-tax reduction.
Foreign engineers who regularly claim overseas dependents, have investment income, or have other deduction reasons should default to the tax-return path.
If You’re Planning to Leave Japan
The resident-tax portion of the furusato nozei benefit reduces your following year’s resident tax. Resident tax itself is assessed based on your status as of January 1 of the year it is billed — and billed from June of that year. The full mechanics are in the resident tax second-year shock explainer.
The practical issue: if you donate in a year and then leave Japan before the following June (when that reduced resident-tax bill would arrive), the timing may not work in your favor. You may not be in the resident-tax system for the year the deduction is supposed to apply, which means you don’t capture the benefit.
There is also a role called 納税管理人 (nozei kanrinin) — a tax agent who can receive tax notices on your behalf after you leave — but this is a separate topic and the furusato nozei timing problem often isn’t fully solvable through that route.
Practical guidance: if you plan to leave Japan within the next 12 months, be cautious about donating large amounts. The ¥2,000 fixed cost is small, and the gifts are real, but the tax deduction that makes the math work may not materialize.
The 2025 Points Rule Change
As of October 1, 2025, portal-site loyalty points — the bonus reward points some furusato nozei portals used to award on top of the municipality’s gift — are no longer permitted under Japanese law. If you’ve used these portals before and remember accumulating points on top of your return gifts, that benefit is gone.
The core mechanics are unchanged: the tax deduction still works the same way, and municipalities still send their return gifts (capped at 30% of the donation). The 2025 change only removed the portal-site points layer. Factor this into your comparison of portals — the points differential no longer exists, so choose based on gift selection and usability.
The Short Version
- Furusato nozei is available to you if you pay Japanese income or resident tax — nationality doesn’t matter.
- Your net cost for the year is ¥2,000, as long as you stay within your personal donation limit.
- Use the official Soumu simulator or a portal simulator to find your limit. The table above is a starting reference only.
- If you donate to 5 or fewer municipalities and don’t file a tax return for any other reason, use the one-stop exception. Submit forms (or submit online) so they arrive by January 10.
- If you file a
確定申告for any reason — overseas dependents, medical deductions, investments — skip one-stop and declare your furusato nozei donations on the return directly. - If you plan to leave Japan in the next year, donate conservatively. The resident-tax deduction that makes the math work applies to the following year’s bill.
- Portal-site bonus points no longer exist as of October 2025. Compare portals on gift selection.
