Tokyo CPI Cools Down, Core Index at 2.3% YoY
As a key inflation indicator for Japan, Tokyo’s Consumer Price Index (CPI) for December rose 2.0% year-on-year, down sharply from 2.7% in November, indicating that inflationary pressures are continuing to ease, though still above the central bank’s 2% target. Core CPI (excluding fresh food) increased 2.3% year-on-year, down from 2.8% last month, marking its lowest level since February and falling short of the market expectation of 2.5%. Core-core CPI (excluding fresh food and energy) rose 2.6% year-on-year, slightly down from 2.8% in the previous month. All three major indicators have remained below 3% since June, signaling that inflation momentum is no longer accelerating.
A closer look at Tokyo’s CPI components shows that falling energy prices are the main driver behind the cooling inflation, with key points as follows:
Energy prices fell 3.4% year-on-year (previously up 1.2%), ending a three-month streak of increases and exerting a notable downward pull on overall inflation.
Processed food prices rose 6.2% year-on-year (previously 6.5%), reflecting ongoing impacts from rice supply shortages; rice prices surged 34.7%, though import costs have stabilized.
Fresh food prices declined (previously up 2.1% year-on-year), further lowering overall CPI growth.
Kindergarten fees fell 60.4% year-on-year (unchanged from the previous month), with government subsidies continuing to curb costs effectively.
Overall, the combination of base effects in energy, slowing fresh food price increases, government subsidies, and a stable yen has contributed to the moderation of Tokyo’s CPI.
In general, all three major Tokyo CPI indicators show a cooling trend, remaining above the Bank of Japan’s 2% target but well below previous peaks, indicating that inflation momentum is gradually stabilizing. In the short term (1–2 months), core CPI is expected to fluctuate within a 2.2%–2.5% range, with limited upside due to energy and food price volatility. In the medium term (within six months), if the yen strengthens and global commodity prices stabilize, inflation may move closer to the 2% target, creating conditions for monetary policy normalization. Conversely, a persistently weak yen and heightened geopolitical risks could push up import costs and inflationary pressures, while rice price fluctuations may amplify increases in food prices.
