Japan’s big cities like Tokyo or Osaka should not be unfamiliar with you. But how about other areas like Nagano Prefecture? In fact, Nagano Prefecture is the area with the highest altitude in Japan. With the average elevation reaching 1,000 m, the water is beautiful, the diurnal temperature variation is huge and the winter is cold, so it provides an ideal environment for agriculture. Its rice production even tops the whole Japan. With these conditions, many outstanding sake breweries are established here, including Senjo Brewery. Despite having a history of over 150 years, Senjo is still thriving and liked by many young sake lovers. But why? It is all about its philosophy.
