REAL-TIME DATA API · AI-AGENT READY · x402 / USDC ON BASE

The average hides the truth. See where Japan's prices are actually gouging.

Headline inflation is +2.0%. But cooking oil is up +12.8%, domestic beef +10.1%, kerosene +9.8% — while rice is down -10.4%. JP-Trade-Oracle surfaces those distortions across 35 price categories (32 CPI categories + 3 service indices), updated from official statistics every 12 hours.

Why an "average" is not enough

Japan's headline CPI is a single number. It hides where price-gouging (nakanuki) is actually happening. Each category has its own year-over-year movement. JP-Trade-Oracle computes a per-category delta — how far each item is running above (or below) the overall inflation baseline — so you can see the real distortions behind the average.
