Hita Tenryosui is sourced from deep geological layers in Hita City, Oita Prefecture, adjacent to the Yaba Hita Hikosan Quasi-National Park and overlooking the Aso Kuju National Park. We produce “Natural Active Hydrogen Water Hita Tenryosui,” recognized alongside the world’s three great mineral waters, at a factory with over 10 billion yen in investments, certified by ISO 22000 and FSSC 22000, and deliver it to customers both domestically and internationally. The discovery of Hita Tenryosui began when eels raised in a specific water source were found to be remarkably healthier and larger than those raised in nearby sources. Research revealed that this water possesses unique and high-quality properties, leading to the creation of “Natural Active Hydrogen Water Hita Tenryosui.” Since its launch in 1999, we have received positive feedback from our customers. We believe that good health enriches life and is an invaluable source of happiness. With the corporate philosophy of wishing for the health of people in Japan and around the world, we have expanded our reach beyond Japan and are now able to deliver our products globally.
