Safe and secure quality control
The secret is our natural, unheated filter processing.
We believe that natural mineral water nurtured solely by Mother Nature is the epitome of pure goodness. To deliver this deliciousness as it is, Haruna Water's manufacturing plants adopt a non-heating method using micro-filter filtration. This process removes even the finest impurities, allowing us to bottle only the natural mineral water. We ensure it retains its natural mineral balance and mind-blowing purity, uncompromised.

Haruna Water has two production facilities, the Azumino Plant and the Matsukawa Plant, located in Azumino, where the majestic Northern Alps rise to heights of 3,000 meters. The snowmelt water from the Northern Alps, which flows year-round at a temperature of 13°C, has been selected by the Ministry of the Environment as one of the top 100 waters in Japan. This abundant spring water, with a daily volume of approximately 700,000 tons, is also ideal for wasabi cultivation, making the region the leading producer in Japan.
