In Japan, there have been federal menstrual leave policies put in place since 1947 to help female employers deal with the effects of their menstrual flows. The 1947 Labor Standards Law enacted a menstrual leave policy for menstruators under Article 68. Specifically, the article states that “when a woman for whom work during menstrual periods would be especially difficult has requested leave, the employer shall not have the said woman work on days of the menstrual period.” However, the policy has lost popularity among women in Japan since its inception in 1947. Why are women not taking advantage of the policy in Japan?
