The Shirakawa Springs is a place so well known that it has been selected as one of the Environmental Agency’s one hundred best water sources (one hundred remarkable waters) in Japan. The water at the spring, which has an average temperature of 14C degrees, gushes forth at 60 tons per minute, and serves as the source of the Shirakawa River, which runs through the centre of Kumamoto city. Water from the spring can be taken for free, heat-treated and sold for public consumption.
