Japan’s Monthly Labour Survey, published by the Ministry of Health, Labour and Welfare (MHLW), is one of the country’s most closely watched economic indicators. The report tracks average monthly cash earnings across establishments with five or more employees, encompassing contractual earnings (scheduled and overtime pay) as well as special cash earnings such as summer and year-end bonuses. Because private consumption accounts for more than half of Japan’s GDP, the survey serves as a key barometer of household purchasing power and a critical input for Bank of Japan monetary policy decisions.

Throughout 2025, the data told a mixed story. Japan’s spring wage negotiations (shuntō) delivered headline increases above 5% for a second consecutive year, yet this momentum did not always translate into the monthly earnings figures. Volatile bonus payments frequently distorted the year-over-year readings — November’s preliminary print showed just 0.5% nominal growth, the weakest in nearly four years, largely due to a steep drop in one-off bonus payments.

By December, nominal wages recovered to 2.4% year-over-year growth, with base pay rising 2.2% and special payments up 2.6%. However, real wages — adjusted for consumer price inflation — declined in every month of 2025, as price increases consistently outpaced nominal pay gains. December’s real wages fell 0.1%, marking the twelfth straight monthly contraction.

This persistent gap between wages and inflation complicates the BOJ’s path toward further rate hikes, as policymakers have conditioned additional tightening on evidence of sustained, broad-based wage gains that meaningfully support household incomes.
