Delicious Soft Mineral Water

Maruyama's natural water 'Yumi Mizu' is a soft water rich in minerals.

Soft water, with its smooth and easy-to-drink quality, is a familiar taste for everyone from children to adults in Japan. It's also attractively easy to use for baby formula and cooking.

Safe and Secure Water

Through Thorough Testing and Management

We draw raw water from underground aquifers and filter it through a four-stage filtration process. It is then bottled in sterile, clean-room conditions using new bottles for delivery. We conduct daily water quality tests and regular radiation checks as part of our commitment to ensuring daily safety and peace of mind.
