The Latest Inflation Picture

In July 2025, Japan’s core consumer inflation (excluding fresh food) rose 3.1% year-on-year, down from 3.3% in June. This marked the lowest level since March, suggesting that price pressures have eased somewhat. Nevertheless, the figure remains well above the Bank of Japan’s (BOJ) 2% target.

Notably, Tokyo a region often viewed as a leading indicator for nationwide trends also recorded a modest slowdown, with core inflation at 2.9%, compared with 3.1% the previous month. This indicates a consistent deceleration not only nationwide but also in major economic centers.

The Special Role of Rice Prices

A key factor contributing to the easing inflation was rice prices. After dominating headlines earlier this year with shortages and surging costs, rice prices have started to cool. Data from Japan’s Ministry of Agriculture showed that an average 5-kilogram bag of rice at supermarkets was priced at 3,737 Japanese yen (about $25.34) in the week ending August 4. At their peak, retail rice prices averaged 4,285 Japanese yen per 5-kilogram bag, while premium brands sold for 4,469 Japanese yen.

The BOJ raised its inflation outlook in the July 31 Economic Outlook Report, projecting core CPI to reach 2.7% for fiscal year 2025 (ending March 2026), up from the previous forecast of 2.2%.

Earlier in May, rice prices had surged at one point to nearly double their year-earlier levels, driving core inflation up to 3.6% the highest in months. However, thanks to government intervention through the release of reserve stocks and improvements in supply, rice prices stabilized in July. The easing of this staple helped alleviate broader price pressures.

Still, processed food and service costs remain elevated. Surveys indicated that in July alone, more than 2,100 food items saw price increases averaging about 15%. This suggests that while inflation from key staples such as rice has moderated, it continues to spread across other sectors.

Monetary Policy: BOJ at a Crossroads

The slowdown in core inflation has put the BOJ in a delicate position. On the one hand, the deceleration reduces the urgency to tighten policy immediately. On the other, inflation remains around 3% still above target signaling that underlying risks have not disappeared.

Analysts suggest the BOJ may consider raising interest rates in October if data continue to show underlying inflation (measured by the “core-core CPI,” which excludes both fresh food and energy) staying elevated. This measure is seen as a critical gauge of true economic overheating, less distorted by temporary shocks.

Moreover, many economists warn of potential “second-round effects” the pass-through of price expectations where households and businesses anticipate further price increases, leading to upward adjustments in wages, services, and contracts. If such effects become entrenched, inflation could persist, moving beyond the reach of temporary policy measures.

Long-Term Implications of the Data

The July data indicate that Japan’s inflation picture has cooled somewhat compared with earlier this year. Softer rice prices are a welcome sign, but they represent only one piece of a more complex puzzle. With processed food, services, and wages still running high, price pressures cannot be dismissed.

Against this backdrop, the BOJ must remain cautious carefully monitoring underlying inflation trends while avoiding policy tightening that could shock growth. Any rate hike later in the year will hinge on whether the disinflation proves sustainable or merely reflects temporary relief from food and energy prices.
