The latest Q4 2026 Tokyo area core CPI index climbed to 103.0, showing an expansionary trend compared to the previous value of 102.5. External data indicates that the year-over-year growth rate in October was 2.6%, matching market consensus and slowing slightly, primarily suppressed by a plunge in rice prices and the base effect of water charges. However, energy prices rebounded against the trend and service inflation remained sticky; the market is closely watching the Bank of Japan's December interest rate decision.
