Japan’s consumer price growth lost steam in August 2026, with the non-seasonally adjusted Consumer Price Index (CPI) rising just 0.1% month-over-month, down sharply from a 0.5% increase in July. The latest data, updated on 17 September 2026, highlight a clear deceleration in short-term price momentum.
The comparison is based on month-over-month changes, with the “actual” figure for August reflecting the increase from July, while the “previous” figure captures July’s change from June. The slowdown from 0.5% to 0.1% suggests easing inflationary pressure on a monthly basis, a development that could influence expectations for price trends heading into the autumn period.
