The lead player in Niigata Prefecture's EV (electric vehicle) subsidies is, perhaps surprisingly, Sado Island. There is no prefecture-level subsidy for individuals, and Niigata City has no vehicle subsidy either (only ¥100,000 for V2H). Amid this, Sado City ran a generous linked subsidy of "one half of the national CEV subsidy amount, capped at ¥400,000" — but it closed in August 2026. It is a design unique to Sado, which champions its "Island of Natural Energy" vision. On the mainland, the national CEV subsidy (up to ¥1.3 million for an EV) is the centerpiece. Here is how to combine them by area.
Update (September 20, 2026): Sado City — the centrepiece of this article — closed its EV subsidy in August 2026. Niigata Prefecture has no individual purchase subsidy, so what remains is the national CEV subsidy.
Think of Niigata's EV subsidies as "two tiers"
CEV subsidy (the lead role in purchases)
A national subsidy available to both individuals and corporations. The FY2025 supplementary-budget round (registrations from April 2026) offers the largest amounts, such as up to 1.3 million yen for EVs.
Sado City takes the lead — capped at ¥400,000
Sado City offers a linked subsidy of 1/2 of the national CEV amount, capped at ¥400,000. Niigata City has no vehicle subsidy (only ¥100,000 for V2H).
No prefectural subsidy for individuals
The prefecture's next-generation vehicle page mainly provides guidance on the national CEV subsidy; there is no prefectural subsidy for individuals. Combine the national subsidy with municipal ones.
[National] CEV Subsidy under the FY2025 Supplementary Budget (registrations from April 2026; the main pillar)
"Up to ¥1.3 million" is a cap. The subsidy amount is decided for each vehicle type by an evaluation of the vehicle's environmental performance and the like. Applications close once the budget runs out. On September 4 the secretariat announced that it expects to stop accepting applications around early to late December 2026 (applications are taken in order of arrival, and intake ends the day before the budget is reached; secretariat notice, PDF, in Japanese). A subsidized car carries a holding obligation of four years in principle; if you dispose of it within that period, repayment may be required. Check the exact subsidy amount for the car you are buying against the amounts published by the Next Generation Vehicle Promotion Center.

[Niigata Prefecture] No prefectural subsidy for individuals
Niigata Prefecture has no EV purchase subsidy for individuals. The prefecture's next-generation vehicle pages mainly provide guidance on the national CEV subsidy, and applications for its charging infrastructure support have already closed. For individuals, combining the national CEV subsidy with municipal subsidies is the basic pattern for the 2026 fiscal year.
[Municipalities] Sado City adds up to ¥400,000 linked to the national CEV
| City/Town | Status in the 2026 fiscal year |
|---|---|
| Sado City | Closed in August 2026 (city page updated August 5, 2026: "applications have closed"). Originally: an amount equivalent to one half of the national CEV subsidy, capped at ¥400,000. Open to individuals and businesses, new cars only (no leases), first registration on or after April 1, 2026, and apply within 60 days of registration (final deadline February 28, 2027) |
| Izumozaki Town | There is information of ¥100,000 for EVs and ¥50,000 for PHEVs (confirm the 2026 fiscal year program on the town's official site) |
| Niigata City | No vehicle subsidy. Only a fixed ¥100,000 for V2H |
Sado City's linked type is designed so that "the larger the national subsidy for a model, the larger the city subsidy": for a car with a ¥800,000 national CEV subsidy, up to ¥400,000 (the cap) is added by the city, potentially reaching a combined scale of ¥1.2 million. The one thing to watch is the short application deadline of within 60 days of registration.
Check the "tax" on EVs too (reductions in automobile tax)
Apart from subsidies, the environmental performance levy of the automobile tax was abolished on March 31, 2026, and it is not charged on vehicles acquired on or after April 1, 2026 (Tokyo Metropolitan Government Bureau of Taxation, in Japanese). For EVs, the automobile tax (type-based levy) for the following fiscal year is reduced by roughly 75% under the greening special provision. For details, see EV taxes and the 2026 automobile tax reform.
Is a subsidy taxed?
An EV subsidy an individual receives is treated as occasional income. Because there is a special deduction of ¥500,000 per year, it is not taxed if, combined with other occasional income, it stays within ¥500,000 for the year. The national and municipal subsidies combined usually stay within this, but watch the total in a year when you receive several large subsidies. Business use is treated differently, so consult a tax accountant or the like.
Summary

- Niigata City has no vehicle subsidy (only ¥100,000 for V2H). Izumozaki Town is reported to offer ¥100,000 for an EV and ¥50,000 for a PHEV.
- CEV subsidy acceptance is expected to close around early to late December 2026 (Reiwa 8). There is in principle a 4-year ownership requirement.
