Sofy and Japan Weather Association Launch 'Menstrual Discomfort Forecast' for Summer Wellness

Unicharm's brand Sofy, in collaboration with the Japan Weather Association, will release the 'Menstrual Discomfort Forecast' on May 18, 2026. This 5-rank index uses meteorological data to quantify discomfort caused by heat and humidity during menstruation. It aims to encourage self-care habits like using cool-type or highly breathable pads, helping women manage summer periods more comfortably. The forecast will be updated weekly on Sofy's official X account.
