This is the first time since 1991 that the figure has surpassed 5 percent, with the raise including both seniority-based increases and base-pay hikes.

The latest labor ministry data showed that amid soaring prices, Japan's real wages in April dropped 0.7 percent from a year earlier for the 25th straight month of decline, the longest since comparable data became available in 1991

Smaller businesses with fewer than 300 employees saw an average raise of 4.45 percent, the highest since 1992, though still lower than the 5.1 percent seen in larger companies with over 1,000 employees.
