Japan Keeps Gasoline at 170 Yen: The 32.5 Yen Subsidy

The current programme is called the emergency mitigation measure in response to the Middle East situation. The money goes to oil wholesalers and importers as a subsidy to cut their wholesale price. Nothing is paid to households directly.

The rate rose from 26.0 yen the previous week (20 to 26 August) to 32.5 yen from 27 August, an increase of 6.5 yen. Because it is reset weekly, the amount working for you depends on the week you buy.

The subsidy has two layers.

Gasoline is not the only fuel covered. Diesel, kerosene and heavy oil all receive the same 32.5 yen, and aviation fuel receives 13.0 yen. For households that heat with kerosene and for transport or construction firms that burn diesel, this matters as much as gasoline does.

METI's petroleum product price survey released on 26 August put the national average pump price for regular gasoline at 169.9 yen per litre as of 24 August, the first rise in four weeks. Here is what makes up that figure.

Note that consumption tax applies to a price that already contains 31.5 yen of fuel taxes, so tax is charged on tax. The National Tax Agency treats gasoline tax and petroleum and coal tax as part of the consumption tax base. Diesel works differently, as explained below.

What would the pump price be without the support? A simple calculation: without the subsidy, about 205.7 yen; without the subsidy and with the old provisional rate still in place, about 233.3 yen. The 32.5 yen subsidy works at the wholesale stage, so with consumption tax it lowers the retail price by about 35.75 yen, and the abolished 25.1 yen is worth about 27.61 yen. Together, roughly 63 yen per litre of tax relief and public money sits under today's price.

The timeline:

• 28 November 2025: the law abolishing the old provisional rates passes the House of Councillors unanimously.
• 31 December 2025: the 25.1 yen/L provisional rate on gasoline ends. Gasoline and local gasoline tax return to 28.7 yen/L.
• 1 April 2026: the 17.1 yen/L provisional rate on the diesel delivery tax ends, cutting it from 32.1 yen to the statutory 15 yen/L after 50 years of "for the time being."
• 21 July 2026: reports emerge of a plan to raise the benchmark to 175 yen in September.
• 25 August 2026: the Prime Minister confirms the 170 yen benchmark and orders funding to be secured.

The two tools do different jobs. Abolishing the provisional rate cut the tax permanently, and its effect is fixed at 25.1 yen whatever crude or the yen does. The subsidy is a variable measure that absorbs price spikes with public money, and the stated reason for keeping it is continued uncertainty over Middle East oil prices.

The money will come from the 2.5 trillion yen Middle East contingency reserve in the FY2026 supplementary budget enacted in June, with several hundred billion yen reported as the likely top-up. Reserve funds can be deployed without item-by-item Diet approval, which is fast but also means less parliamentary scrutiny.

Assuming a car at 15 km/L and that today's 32.5 yen rate (about 35.75 yen including consumption tax) and the abolished 25.1 yen (about 27.61 yen) both hold for a full year.

For a typical household driving 10,000 km a year, roughly 42,000 yen. More than half of it comes from the subsidy, the part that can disappear at any time, rather than from the permanent tax cut. At 20 km/L read about 75% of these figures; at 10 km/L, 1.5 times. Switching to an electric vehicle removes both, and replaces them with a different set of vehicle taxes, covered in EV taxes and the vehicle tax reform.

On 21 July 2026, several outlets reported a plan to lift the benchmark to 175 yen from September, holding the current level through August when holiday demand peaks and trimming afterwards, with a shrinking fund balance in the background.

A month later the Prime Minister confirmed 170 yen, citing continued uncertainty in the Middle East, while adding that the shape of the support would be reviewed flexibly in light of prices and the economy. The 175 yen plan looks postponed rather than withdrawn. A 5 yen move in the benchmark would raise the pump price by a little over 5 yen including tax, about 3,700 yen a year for a household driving 10,000 km.

Three things to watch: how much of the reserve is actually added to the fund; crude and the yen, since the variable portion shrinks automatically when the average falls toward 170 yen; and the year-end tax debate over how to handle the roughly 1.5 trillion yen of annual revenue lost to the abolition, alongside the FY2027 tax reform requests. Electricity and gas support follows the same pattern, covered in the restart of electricity and gas subsidies.

Fuel is deductible either way, but the consumption tax treatment differs, and always has.

The authority is National Tax Agency guidance No. 6313. Gasoline tax and petroleum and coal tax are owed by the manufacturer, so they form part of the price and sit inside the consumption tax base. The diesel delivery tax is owed by the buyer, so where the amount is shown separately on the invoice or receipt and booked clearly as a deposit or advance, it stays out of the base.

• Receipts that do not itemise the diesel delivery tax are easy to book in full as taxable purchases. Check whether your station itemises it; if not, the whole amount is treated as a taxable purchase.
• The diesel delivery tax fell from 32.1 yen to 15 yen on 1 April 2026, so the out-of-scope amount dropped by 17.1 yen per litre and taxable purchases rose accordingly. Watch the switchover date in your books.
• The fuel subsidy never appears in your accounts. It is paid to wholesalers and importers; you simply buy at a lower price. There is no miscellaneous income to record. Separate local government fuel support schemes, if you receive one, do have to be booked as income.
