Japan real wages grow for first time in 13 months, boosting BOJ hike case

TOKYO, March 9 (Reuters) – Japan’s ‌real wages climbed in January for the first time in 13 months as inflation cooled, with ​base salaries growing at their fastest pace in ⁠33 years, government data showed on Monday.

The positive turn ​strengthens the case for the Bank of Japan to keep raising interest rates and normalise monetary policy. It last hiked in December to 0.75%, a ​level still very low ​compared to most economies.

Inflation-adjusted real wages, a key barometer of consumer purchasing power, rose ​1.4% in January from a year earlier, rebounding from a 0.1% decline in ⁠December.

Average nominal wages, or total cash earnings, increased 3.0% ​year-on-year to 301,314 yen ($1,911), marking their fastest pace since July and accelerating from December’s 2.4% gain.

The pay growth was enough ‌to outpace the consumer inflation rate the ministry uses ‌to ​calculate real wages. That was 1.7% in January, the slowest gain since March 2022, thanks to fuel subsidies and fewer ​food price hikes.

Regular pay or base salary grew 3.0%, the ​biggest rise since October 1992 and up from a revised 2.1% in December. Overtime pay jumped 3.3%, rising from a revised 1.5% the previous month to its highest level in about three years.

Special payments, consisting mostly of one-time bonus payments, increased ‌3.8% in January, up from December’s revised 2.7%.

The upbeat ​wage data comes as the central bank convenes for a rate review on March ​18-19, coinciding with the conclusion of this year’s wage negotiations. It has said it will focus on whether wage gains will broaden ​and ⁠give households purchasing power when judging ​how soon to hike rates.

Japan’s largest union group, Rengo, last week said its member unions are seeking an average wage hike of 5.94%, underscoring strong momentum after an ‌average 5.25% raise in 2025, their biggest in 34 years.
