Soap kind to people & nature Kettle-cooked additive-free* soap

“Maruha Yushi-Kagaku” is located near the majestic Chikugo River, in Kurume, Fukuoka. Since its establishment in 1932, it has been producing additive-free* soap with natural ingredients and traditional framing methods such as “kettle-cooking” and “natural drying”. The founder, Mr. Juemon Hayashi, who was very much the scholar and favored study, founded the company in Kurume after he had learnt the techniques of soap-making in Tokyo.

Since then, this passion toward making gentle-to-the-skin soaps has been firmly handed down to Shinichi, the third generation of the company. The soap is made by neutralizing natural oils and fats with alkaline sodium hydrate. Since it returns back to original oils and fats when it comes into contact with acidic substances, it has little effect on the environment.

The reason why Maruha Yushi-Kagaku has stuck to making soaps without synthetic surfactants, antioxidants, synthetic dyes and preservatives is its consideration not only for your skin, but also for the environment. Thus their soaps decompose after use and return to nature. The rich nature of the Chikugo River may be another reason that they’ve been producing soaps kind to people and nature.


*Additive-free = Does not contain any synthetic surfactants, antioxidants, preservatives including paraben etc., chelating agents such as EDTA-4Na.
The grand Chikugo River runs through south Fukuoka. Located in the middle of the fertile Chikugo plain, Kurume is popular for ramen and delicious sake.

Carefully made over 90 days The kindness of hand-making & long-maturing

They are proud of having 4 kinds of kettles in different sizes which can make any ingredients into soap. These kettles are used according to the ingredients which are blended differently depending on each product. They are cooked in the kettle at nearly 100℃ for 2 to 3 hours, and the impurities are removed by adding salt water. The judgement of “saponification and salting-out” is carried out using the ultimate skills of craftsmen who taste the mixture to check the alkali concentration. After that, the mixture is poured into the frame so that air no longer remains, and then carefully kneaded. In order to make the texture even smoother, irritants are removed by thoroughly drying and maturing. In this way, one soap is made through the hard labor of craftsmen over a period of 90 days.

High-purity additive-free * soap ”Tsubaki Uruoi”

Maruha Yushi-Kagaku developed ”Tsubaki Uruoi” to celebrate the 77th year since its establishment. It’s a high purity additive-free* soap that is made using natural camellia oil from Goto Islands, Nagano, which is famous for its high-quality camellia oil. Also, honey, squalene, orchid, yuzu peel oil and tea extract are added for more moisture.
Camellia oil has been traditionally used to keep Japanese women’s skin and hair beautiful. When Shinichi was young, his mother also used camellia oil everyday. He had wondered if he could make the amber liquid into a soap and also hoped to use local ingredients from Kyushu. Holding these 2 thoughts over a long period of time motived him to produce “Tsubaki-Uruoi”, and he succeeded in acquiring camellia oil from Goto Islands which is said to be difficult to supply stably.

What gently wraps the soap up is “Yame hand-made washi paper”, a traditional craft from neighboring Yame. Also, a brilliant and unique “Hakata Mizuhiki” ties up the wooden box from Fukuoka. The mizuhiki has an auspicious “awabi-musubi” knot that represents camellia leaves.
