Introducing MOIS ET JOUR: A Revolutionary Feminine Wear for Active Women

Launch of MOIS ET JOUR: The Next-Gen Menstrual Underwear

On March 5, 2026, a groundbreaking lingerie brand named MOIS ET JOUR will debut, designed specifically for active women who refuse to compromise on style during their menstrual cycles. Created by FOR Inc., headquartered in Minato City, Tokyo, this innovative brand aims to redefine menstruation by transforming it from a taboo into a natural rhythm of femininity.

Rethinking Menstruation

MOIS ET JOUR, which translates to 'Month and Day' in French, draws inspiration from the stylish fashion scene of France, merging it with the natural menstrual cycle – a unique experience intrinsic to womanhood. This brand symbolizes a significant shift in how society perceives menstruation; it's not a discomfort, but rather a natural process that should be embraced and celebrated.

The product boasts an impressive absorption capacity of 45ml, equivalent to four regular daytime sanitary pads, thanks to its advanced five-layer design that incorporates odor-resistant technology. Developed through interactions with over 4,000 women in various salons, MOIS ET JOUR's underwear prioritizes both comfort and style, providing a chic and empowering choice for women during menstruation.

Brand Philosophy: Fashion × Period

The core theme of MOIS ET JOUR is 'Fashion × Period', advocating for a lifestyle where menstruation is seamlessly integrated into daily life without feeling restricted. The brand invites modern, bold women to take ownership of their bodies and experiences, celebrating their personal beauty regardless of the time of the month.
