Toyama Quality Water



To all the people living healthy and gracefully every day.

For more than 70 years, Goshu has been researching and developing bath additives and skin care cosmetics. "Toyama Quality Water", we launched as a flagship brand. By using two natural ingredients "groundwater" and "deep sea water" into skin and body, we would like to contribute to people’s beauty, health, happiness and beyond.

Two in

Natural water

We are pumping up natural water containing minerals from our own factory built in a natural abundant forest. After long years, blessed deep underground, the splendid water is alkalescent with almost the same pH 7.2 as human blood. It is gentle on the body with a mellow taste.

Deep sea water

Deep sea water contains well-balanced minerals essential to the human body. It is almost impossible to make artificially comparable to deep sea water where sunlight does not reach and is kept at low temperature in a sterile state. That unlimited possibility is also drawing attention in the fields of healthy drinks, food and pharmaceuticals.
