It is a bit difficult to know what is actually going on here, certainly bonuses must be part of the picture. Employees at manufacturers worked less overtime in April as production slowed, limiting wage growth for the month, according to Shunichi Ando, head of the Labor Ministry's statistics division. Working hours at manufacturers fell 4.1 percent, the biggest drop in six years. In construction, however, overtime was up 11% y-o-y.
The number of people employed on a full-time basis rose 2 percent year on year, exceeding the 0.8 percent increase in part-time staff, as new labor rules lead companies to treat more temporary workers as permanent employees.

Hiring of full-time workers has been accelerating since October as companies anticipated the new labor regulations, which came into effect on April 1. The 0.8 percent increase in part-time staff last month was the slowest rate of increase for part time workers since December 2005.
