Japan's Ministry of Health, Labour and Welfare released its labour cash earnings data on Tuesday. Labour cash earnings in Japan dropped at an annual rate of 2.4% in June, after a 0.7% rise in May.
May's figure was revised up from a 0.6% gain.
The decline was partly driven by a fall in bonuses. Bonuses in June plunged 6.5% year-on-year.
Wages, excluding bonuses and overtime, climbed 0.4% in June.
