Japan Inflation Rate (CPI)

What it measures

This measures how much consumer prices in Japan have risen over the past year, the yearly inflation rate. It matters more for Japan than almost anywhere else because the country spent decades stuck with falling or flat prices, so the Bank of Japan watches inflation to decide whether it can finally keep lifting interest rates away from near zero. The number to focus on is core inflation, which strips out fresh food (and sometimes energy) because those prices jump around for reasons that have nothing to do with the underlying trend.

Higher rates reward holding a currency, because money flows toward where it earns more, so signs that inflation is settling in tend to support the yen by making future Bank of Japan rate hikes more likely. What makes Japan unusual is that the Bank will not raise rates on a strong inflation print alone; it needs to believe prices and wages will keep climbing together, so traders read this number against whether pay is rising too, with the spring wage round (the Shunto) as the key signal. Judge the figure against the forecast and against the pace that would convince the Bank inflation is durable rather than a one-off from imported costs, since inflation driven only by a weak yen pushing up import prices can actually argue for a hike while also reflecting a soft currency. Keep two other yen traits in mind: it is a safe haven that can strengthen on global fear regardless of Japanese data, and it is the cheap currency people borrow to buy higher-yielding ones, so a clear shift toward hikes can force those carry trades to unwind and snap the yen sharply higher.
