■ Comment from Musashino Art University

From April 2026, Musashino Art University has installed "OiTr" in women's restrooms on campus and has begun providing sanitary products free of charge. At our university, many female students are dedicated to their creative work and research every day in a campus environment with specialized facilities and equipment that support diverse creative activities. This introduction began with a proposal from volunteer faculty and staff to support these students, and it was realized with the great cooperation of OiTr Inc. All faculty and staff will continue to strongly maintain their commitment to supporting each student and strive to create an environment where everyone can study with peace of mind.

■ About "OiTr"

OiTr is a service that allows users to receive sanitary napkins for free from a dispenser in a women's private restroom. By downloading the dedicated app (free) and registering an account, you can receive one napkin every 2 hours. Furthermore, you can receive up to 7 napkins every 25 days from the account registration date.
As of March 2026, OiTr has been installed in 367 facilities across 34 prefectures nationwide, with a total of 4,120 units.

In addition to receiving napkins, the app also offers "period prediction" and "health management" functions, with users commenting on its convenience for "receiving napkins while recording" and the accuracy of its predictions. Furthermore, through the media "Itsudemo OiTr," which alleviates women's anxieties, information on women's mental and physical concerns, menstruation, and health is disseminated, supporting a society where women can make positive choices with peace of mind.

■ The Background of OiTr's Birth

OiTr Inc. started with the mission of "solving social issues through business." Among these, the issue of "period poverty" caused by gender inequality attracted attention.

In Japan, there are women who cannot access sanitary products or hygienic environments due to economic and social reasons, which leads to invisible social losses such as loss of educational opportunities, difficulty in employment, and psychological burden.
"Why are sanitary products not always available in private restrooms, when toilet paper is?" — Prompted by this simple question, our company began efforts to change social awareness and the environment, starting from the most familiar restroom spaces in daily life.

■ Initiatives for "Period Poverty"

In Japan, "period poverty" tends to be viewed as an economic problem, but globally, it refers to a state where people lack access to not only sanitary products but also clean water, hygienic environments, and education on biology and reproduction—the minimum necessities for menstruation. Lack of access to sanitary products is not merely a material problem; it profoundly affects dignity, health, education, and labor throughout life. While measures such as free provision, reduced tax rates, and tax abolition are progressing worldwide, in Japan, support remains limited to local government units.
Our company hopes to create an environment where sanitary products are "naturally available" in daily life, providing an opportunity to re-examine what has been considered "normal." We hope that this initiative will be the first step towards a society where everyone can live with peace of mind, and that greater empathy and action will spread.
