In October 2013, the trading company Itochu began to move away from a way of working that took night overtime for granted. Overtime after 8 p.m. was banned in principle and needed advance approval. Work after 10 p.m. was banned, and overtime was shifted to the next morning.
Newsweek Japan reported that work between 5 and 8 a.m. carried a wage premium of 150 percent.
