The government calls the working style “yukatsu” — a way to enjoy the sunset, or yuyake, hours, as a time for oneself — and is hoping to make it a national trend. Such a work system will be introduced in central government ministries and agencies from July, in the hope of addressing the prevalence of prolonged working hours. In June, Sompo Japan Nipponkoa Insurance Inc. began encouraging about 2,600 employees at its Tokyo headquarters to shift their working hours earlier by one hour or more, from the regular 9 a.m.-5 p.m. to 8 a.m.-4 p.m. or earlier. It also prohibits overtime after 7 p.m. in principle. The company will increase the number of employees targeted in the move to about 27,000 nationwide from July, and will maintain the adjusted working pattern until the end of October. It will then review the effects to decide whether to expand the practice or to further increase the number of employees covered by it.
