Let's look at some of Matsuyama's most commonly used raw materials and ingredients. We strongly believe that "quality begins with materials." Indeed, our manufacturing process stretches all the way back to the materials themselves, choosing those that offer optimum balances of safety, environment-friendliness and usefulness, and often growing, harvesting and processing the plants at our own farms.

The conditions under which they are manufactured and filled significantly influence the quality of soap and skincare products. To maintain high levels of quality, our production, R&D, and quality assurance units work in close coordination to identify and apply optimum production methods throughout our processing-- Kamadaki (pot-cooking), frame kneading, milling, neutralization, mixing, and emulsification.
