“Make” water instead of “Stocking” water

Sarastear's brand name comes from the idea that the water that heals and comforts (Solace) the body and soul is created from a droplet (Tear) and cultivates lives.
Today, water shortage has become a serious problem around the world including Japan. Sarastear does not provides conventional water servers that does not only store water, but creates water to supply the healing drops all over the world.

For the people all over the world, to supply safe and secure water created from the air.

For the people all over the world, to supply safe and secure water created from the air.

Water that quenches thirst, cultivates food, and is essential to life. Today, living in Japan makes us think that "safe and secure" is the norm, however, there are reportedly approximately 800 million people who do not have access to safe drinking water worldwide*1

The water server Sarastear project, to create drinking water from air, started with the goal of creating the future where everyone in the world can drink "safe and secure water" easily.
