Tokyo’s core consumer price inflation eased in May 2026, with the key gauge slowing to 1.3% year-over-year from 1.5% in April, according to data updated on 28 May 2026. The core CPI reading tracks price changes excluding certain volatile components and is closely watched as an early signal of nationwide inflation trends.
The May figure marks a further moderation in underlying price pressures compared with the same month a year earlier, extending the deceleration seen in April. On a year-over-year basis, the latest reading indicates that while prices in Japan’s capital are still rising, the pace of increase continues to soften compared to earlier in the year.
Because Tokyo’s data are released ahead of the national CPI, the May slowdown in the city’s core inflation will likely factor into expectations for Japan’s broader inflation outlook and potential policy considerations in the coming months.
