Matsuyama Yushi (Matsuyama)

What is "Matsuyama Yushi," pursuing the balance of safety, environmental friendliness, and usefulness?

Matsuyama Yushi (Matsuyama) is a long-established manufacturer that was founded in 1930 (Showa 5) as a general goods store, and began soap production right after the war. With bases in Sumida-ku, Tokyo and Fujikawaguchiko-cho, Yamanashi Prefecture, the company manufactures everyday items such as body care, hair care, and skincare — using its core technologies of traditional "kettle-boiled production" and "transparent soap production (fatty acid neutralization method)."

At the foundation of Matsuyama Yushi\'s manufacturing is the basic philosophy of "satisfying the balance of safety, environmental friendliness, and usefulness." Beyond simply removing dirt, the brand considers gentleness to the skin and the impact on the water environment after rinsing. Because these are things used every day, the honest stance of formulating with simple ingredients — only what is truly necessary — has gathered support from many users.

Representative Brands & Series

Matsuyama Yushi develops multiple brand lines according to purpose and preference. Here we introduce two of the most representative series.

M-mark series

A daily care series that could be called the origin of Matsuyama Yushi, born in 1995. Under the concept of "formulating only the ingredients that allow you to use it comfortably every day, all the way to the end — rather than adding various things," the lineup contains items that all family members can use, regardless of age or gender.
In particular, the "kettle-boiled soap" that craftsmen spend 100 hours boiling, and the "Yuzu Body Lotion" with high moisturizing power and good skin compatibility, are long-selling products that represent the brand.

LEAF&BOTANICS

A skincare and body care line for feeling the "blessings of plants" — from fruits and leaves — with both skin and heart. All items are formulated with natural essential oils, and the natural fragrances of lavender, grapefruit, geranium, and others turn daily care into a relaxing time that calms the heart. Often adopted as hotel amenities, the refined package design is also part of the appeal.

Frequently Asked Questions about Matsuyama Yushi

Q. Where can I purchase the products?

A. They are available at the official online store, as well as at lifestyle goods stores and drugstores nationwide.
In addition to direct sales at the official online store (store.matsuyama.co.jp), the products are carried at a wide range of stores including variety shops such as Loft and Hands, some drugstores, and supermarkets. You can also purchase directly at factory shops (directly managed stores) attached to the Sumida Factory and Fujikawaguchiko Factory.

Q. How is "kettle-boiled production" soap different from ordinary soap?

A. Natural moisturizing components (glycerin) remain in the soap, making the after-wash feel moist.
The traditional kettle-boiled production (oil saponification method) is a traditional method where craftsmen judge the kettle\'s state and slowly boil the soap for about 100 hours. Although it takes effort and time, soap made with this method naturally contains moisturizing components that ease dryness and tightness — washing the skin cleanly while preserving moisture.

Q. Can it be used on sensitive skin?

A. The formulation minimizes ingredients that could irritate the skin, but a patch test is recommended first.
In particular, the "M-mark series" additive-free soap does not use synthetic surfactants, mineral oil, fragrances, colorings, or preservatives, making it a formulation that is easy to use for people with sensitive skin and small children. However, since not everyone is free from allergies or irritation, those who are concerned are recommended to test on the inside of the arm before use.
