Tokyo inflation rises to 2.8% in October as core measures slow
Key Facts
Tokyo’s headline consumer price index rose 2.8% year on year in October, up from 2.7% in September, and increased 0.5% month on month on a seasonally adjusted basis, according to preliminary data published by Japan’s Statistics Bureau on October 30. The annual increase widened by 0.1 percentage point, with fresh food contributing 0.26 percentage point. But measures excluding volatile components slowed, showing a divergence between the rise in the headline index and declines in core inflation measures. The report was released before the Bank of Japan announced its monetary policy decision later that day, with Tokyo data used as an early indicator of the national trend. The reading therefore sets food and energy pressures against slowing core price measures ahead of the bank’s decision.
The index excluding fresh food rose 2.6% year on year in October, compared with 2.7% in September, and increased 0.3% month on month on a seasonally adjusted basis. The index excluding fresh food and energy also rose 2.6% year on year, after 2.9% in September, and recorded a seasonally adjusted monthly increase of 0.2%. That means both core measures slowed year on year, despite rising from the previous month after seasonal adjustment. Nationally, the headline index rose 2.1% in September, while the index excluding fresh food increased 2.1% and the index excluding fresh food and energy rose 2.4%. The comparison between Tokyo and the national reading shows that core inflation measures in the capital slowed in October from September levels, while the headline index remained above those measures.
In food, fresh fish prices rose 14.2% year on year in October, fresh vegetables climbed 10.5% and meat increased 6.4%, while prices for dining out rose 4.6%, according to the Statistics Bureau. Fresh food helped widen the annual increase in the headline index, but food prices excluding fresh items followed a slower trend, rising 3.0% after 3.6% in September. This component’s contribution to headline inflation narrowed by 0.12 percentage point in October. The price of rice other than Koshihikari also fell 31.3% year on year, contrasting with the increases in fish, vegetables and meat. These moves combine sharp rises in fresh food categories and higher dining-out prices with slower inflation in non-fresh food and a decline in the cited rice category.
The divergence also extended to energy, whose prices shifted to an annual increase of 2.2% in October after falling 1.9% in September. Electricity rose 1.7% year on year, after declining 2.6% in September, while city gas increased 4.9% after falling 0.5%. The shift to increases in electricity and city gas widened the headline index’s rise by 0.18 percentage point. Rents rose 1.9%, while hotel accommodation prices increased 6.7% year on year, contributing 0.05 percentage point to the rise in the headline index. Energy and accommodation, along with fresh food, thus helped lift the headline index, while inflation measures excluding fresh food and energy slowed.
In the monetary policy context, the Bank of Japan raised its benchmark interest rate in September to 1.25% from 1.0%, its highest level in 31 years. Governor Kazuo Ueda said Japan’s economy continued to recover gradually and inflation was close to the bank’s 2% target. After the September decision was announced, the Nikkei 225 rose 1.4%, a reaction linked to that rate decision rather than to the Tokyo data published in October. In July, the bank had forecast inflation of 2.5% in fiscal 2026 for the index excluding fresh food, followed by 2.4% in 2027 and 2.0% in 2028. The bank said inflation was likely to remain clearly above 2% from the second half of fiscal 2026 before moving toward that level through fiscal 2028.
The Bank of Japan said price risks were tilted to the upside for fiscal 2026 and 2027, citing the weak yen and strong global demand linked to artificial intelligence, as well as developments in the Middle East, as sources of risk. It added that it would continue raising interest rates and adjusting the degree of monetary easing in response to developments in economic activity, prices and financial conditions. The monetary policy meeting was scheduled for October 29 and 30, with the Summary of Opinions set for release on November 10 and the minutes on December 23. The Statistics Bureau scheduled the preliminary Tokyo-area consumer price index for November for release on November 27, 2026. That reading will provide a subsequent update on movements in the headline index and its core measures after October’s data.
