We believe that food (brown rice and natural foods), movement (moderate exercise), and the heart (mental stability) are the three elements that must be in harmony to promote health. Among these, food is the key to true health. In 1988, we built the Toya Health Hall on a hill overlooking the Toyako National Park. We use fresh, safe and reliable local vegetables and brown rice to create healthy natural food dishes for you to enjoy. We built a health information base in Ryogoku, Tokyo called the Ryogoku Eco Building, where we promote healthy eating, and introduce and carry natural foods, and operate a natural foods restaurant.
