Founded in Hiroshima in 1970, we began with the door-to-door sales of detergents. Since then, we have evolved as a cosmetics manufacturer, developing our brand “La Sana” under the concept: “A Promise of Beauty—Always and Forever.”
As a nationwide cosmetics company, we specialize in four key categories: Hair Care, led by our signature “Leave-in Hair Treatment”; Skin Care, including facial soaps and lotions; Bath Products, offering powder and salt-based options; and Aroma, featuring essential oils and diffusers.
Guided by our philosophy of “Contributing to a healthy lifestyle that is true to oneself,” we develop, manufacture, and sell cosmetics that harness the blessings of nature from three sources: seaweed, the ocean, and plants. Our leave-in hair treatment has achieved the No.1* market share in Japan, as we continue to advocate for beautiful hair care.* Based on post wash treatment results in the Post Wash Treatment category between 2008 and 2019 (research by Fuji Keizai)
