Through this agreement, the Company will begin offering free access to the "Premium Course," a paid feature of "Lunaluna," its women's healthcare service that supports women throughout their lives, to residents of Ishikawa Prefecture starting July 6 (Mon). "Lunaluna" provides various information, including daily health management and basic knowledge about fertility and infertility treatment, allowing users to receive health information tailored to their life stages.

Furthermore, through this initiative, a verification study will be conducted to assess whether the app and information provided by "Lunaluna" can contribute to fertility efforts within households.

1. Background of the Partnership Agreement

Ishikawa Prefecture aims to achieve "Japan's No. 1 Happiness" by promoting the creation of an environment where people can have and raise children with peace of mind, and a society where people can live healthy and secure lives throughout their lives. As part of this effort, the prefecture is working to disseminate correct knowledge about sex and health to a wide range of age groups, starting with young people from puberty, and to enhance support for those who wish to conceive.

The Company launched its "Lunaluna" service in 2000. By utilizing the big data accumulated in "Lunaluna" and its proprietary ovulation prediction algorithm*1, the Company leverages 25 years of accumulated know-how and knowledge to support women's health across life stages, including menstrual management, fertility, pregnancy, childbirth, childcare, and menopause.

Against this backdrop, the partnership agreement has been concluded to enable both parties to cooperate and support women's health management.

2. Areas of Partnership and Cooperation

Utilizing "Lunaluna" provided by the Company, we will cooperate and collaborate on the following matters: (1) Dissemination and promotion of correct knowledge regarding women's health management from a young age, including puberty. (2) Dissemination and promotion of correct knowledge and support regarding pregnancy, childbirth, infertility, and recurrent miscarriage. (3) Support for couples wishing to conceive. (4) Other matters deemed necessary by both parties.
