Sustainable development goals

SDGs of Cleansui include efforts to resolve the water-related environmental issues, provide clean water, and production of sustainable products and services. We have initiated a program named “Encourage Japan with the power of water!” which supports people affected by natural disasters in Japan, and a campaign “Drink the tap water!” In addition, we have attempted to change the mindset of our employees through the “mymizu Challenge.” In July 2021, we opened the Cleansui House in Vison, a commercial complex located in Taki-town of Mie, which aims to become the center of SDGs in Japan. Moreover, we are attempting to expand our activities through the Cleansui House, where guests can enjoy the taste of Cleansui filtered water, exhibits related to water, and participate in workshops.

Cleansui has been aggressively promoting water-related projects in collaboration with various partners such as experts in food, sake brewing, accommodations, and apparel brands. We have developed a water purifier that mimics the water for Washoku, a water cuisine. In addition, an aesthetically pleasing water purifier that harmonizes with a house interior was developed in collaboration with traditional Japanese craftsmen. We will launch new water-related projects in the near future.
