Japan core CPI September 2026: 2.1%, above BoJ's 2% target

Japan core CPI September 2026 data show prices excluding fresh food rose 2.1% year on year, up from 1.7% in August and the first reading above the Bank of Japan's 2% target since December 2025, the Statistics Bureau said on 23 October.

Key takeaways

• Japan's core CPI, which excludes fresh food, rose 2.1% in September from 1.7% in August, in line with the market forecast.
• Headline CPI also rose 2.1%, up from 1.9%. The "core-core" measure, which strips out fresh food and energy, climbed to 2.4% from 1.9%.
• Durable goods, utility charges and services drove the increase. Rice prices fell 20.6% and energy fell 0.6%, held down by government subsidies.
• The Bank of Japan's policy rate is 1.25% after a hike on 18 September. Its next meeting ends on 30 October, and many analysts polled by Reuters expect the next hike in December.

Japan core CPI September 2026: the headline numbers

The Statistics Bureau of the Ministry of Internal Affairs and Communications publishes the national consumer price index monthly. Since the August report, the index uses 2025 as its base year (2025 = 100). For September 2026, the bureau reported:

• All items (headline): index 102.2, up 2.1% year on year.
• All items less fresh food (core CPI): index 102.3, up 2.1%.
• All items less fresh food and energy (core-core): index 102.8, up 2.4%.

The core reading matched the median forecast, Reuters reported. ActionForex noted that core CPI was back above 2% for the first time since December 2025. FXStreet reported that the August figures had been revised to 1.8% for core and 2.0% for core-core, from the 1.7% and 1.9% first published. Either way, both measures accelerated clearly in September.

Prices also rose quickly over the month. On a seasonally adjusted basis, core CPI rose 0.5% from August, according to figures compiled by ActionForex. That compares with 0.1% the month before.

What pushed Japanese inflation higher in September

The breakdown shows a shift in where prices are rising. Food is no longer the main driver. The pressure now comes from manufactured goods, utility charges and, more slowly, services.

Durable goods and utility charges

Household durable goods prices rose 6.2% from a year earlier, up from 3.9% in August. Broader industrial products rose 3.9%. Reuters linked the price pressure to higher fuel costs from the prolonged conflict in the Middle East and a weak yen, which raises the cost of imports. It also cited strong demand related to artificial intelligence. Water charges swung from a 3.5% fall in August to a 4.9% rise, and accommodation turned from -1.4% to +4.6%.

Services inflation edges up

Services prices rose 1.5%, up from 1.2%. Services are still well below goods inflation, but they matter more to the Bank of Japan because they reflect domestic wages. Reuters reported that companies are passing higher labour costs on to customers as the job market stays tight.

Rice and energy keep a lid on the headline rate

Two items pulled the other way. Rice prices were 20.6% lower than a year earlier, after the sharp jump in rice prices in 2025. Energy prices fell 0.6% year on year, with electricity and gasoline both down 2.4% and 2.6%.

Government support explains much of the energy reading. In a press conference on 25 May, Prime Minister Sanae Takaichi announced help with electricity and gas bills for July to September: 3.5 yen per kilowatt-hour in July and September and 4.5 yen in August, at a cost of about 500 billion yen. Reuters said these fuel subsidies offset only part of the rise in costs. That is why the core-core measure, which excludes energy altogether, rose faster than the core index.

What it means for the Bank of Japan

The Bank of Japan raised its short-term policy rate by 0.25 percentage point to 1.25% on 18 September, the highest level since 1995, according to RTTNews and Reuters. The board voted 7–2 for the move. Its next Monetary Policy Meeting runs on 29–30 October, followed by a meeting on 17–18 December, according to the central bank's published schedule.

Most analysts quoted after the release do not expect a second hike in a row next week:

• Reuters, citing sources familiar with the central bank's thinking, reported that the BoJ is likely to keep rates on hold in October. It may raise its inflation forecasts and say that underlying inflation has probably reached 2%.
• Masato Koike, senior economist at Sompo Institute Plus, told Reuters there was "little need" for back-to-back increases because price rises are not accelerating sharply. He expects the next hike in December.
• Marcel Thieliant, head of Asia-Pacific at Capital Economics, expects the BoJ to hold next week and flag upside inflation risks. He said the risks point to a higher peak in the policy rate than his firm's 2% forecast.
• Many analysts in a Reuters poll expect the policy rate to reach 1.50% in December and see the end point of the cycle at roughly 1.75% to 2%.

Governor Kazuo Ueda has said the bank will not tolerate inflation overshooting its target, Reuters reported. The September data support that concern in two ways. First, core-core inflation is now well above 2% even though energy is falling. Second, the jump in month-on-month prices suggests that cost pass-through is still under way. The October meeting will also bring the BoJ's quarterly Outlook Report, so any changes to its price forecasts will show how the board reads these figures.

Impact on households and policy

For households, the mix matters more than the headline rate. Cheaper rice and subsidised electricity are offsetting more expensive appliances, processed food and some services. The summer power subsidy announced in May covered July to September only. Reuters reported that businesses are still passing higher fuel and import costs on to consumers, which helps explain why prices excluding energy are rising faster than the headline index.

For the government, the data come at a sensitive time. Prime Minister Takaichi has framed this year's energy support and extra budget as a response to inflation linked to tensions in the Middle East. Any new subsidy decision will directly shape the energy line in the coming CPI reports.

What is still unknown

The government has not said whether it will extend electricity and gas support beyond September. The Bank of Japan has not signalled the timing of its next move. Its 30 October statement and Outlook Report are the next official guidance.
