​La Serre, an ancient castle dating from the 15th century, is located in the south of France. It is still used as a residence and has been passed down from generation to generation. The castle is also home to Sirius, a company that handles organic raw materials and develops and manufactures products using high-quality organic natural raw materials from around the world. In Japan, the quality of the botanical ingredients and the products we handle are highly regarded, and we are engaged in product development with many raw material companies and cosmetics companies that agree with our concept of sustainability. In order to maintain sustainable plant cultivation and production, we have an organic field in the castle where we grow lavender and other essential oil plants.
