FDA stands for the U.S. "Food and Drug Administration." It is a governmental agency within the Department of Health and Human Services and enforces the "Federal Food, Drug, and Cosmetic Act." It is similar to the Ministry of Health, Labor and Welfare in Japan. It approves and regulates the distribution of food and drugs etc. and is responsible for protecting the public health of U.S. citizens.

● Water

The water we use to manufacture clay is the undercurrent water from Mt. Fuji. The water comes from the melting snow of Mt. Fuji, and takes ten or more years to percolate through the lava bed of the mountain. We pump up the water from 100 meters below at our well in our Gotemba factory.

As stated above, our products are made from carefully selected ingredients and safety checked. Even so, our products are made strictly for plastic arts and not for other uses (ex. eating, drinking, putting in the eye, etc.), so do not use them for purposes other than what they are made for. Doing so may cause suffocation or blindness. Because each person's constitution is different, if you feel any pain or find any changes when using the products, stop use immediately and consult a doctor.
