Miracle Limestone
300 million years ago, magma created a seamount near the Big Island of Hawaii in the Pacific Ocean. Eventually, coral reefs were formed on the summit.

Millions of years made the coral reefs into limestone. And sea plates carried the limestone to Japan over 80 million years.

This limestone is one of the purest limestones in the world. YAMAMOTO only uses the highest-grade of limestone, containing 99.7% Calcium Carbonate as a raw material.

Blessing of flowers
Although certain amount of oil is needed to make soft rubber foam, YAMAMOTO stopped using petroleum-derived oil.

Instead, YAMAMOTO uses food-grade pure Canola oil, which is widely used as Tempura oil in Japan for sustainability and safety.

Think of ocean pollution
The beautiful blue sea is now in danger of being covered by marine debris.
It is estimated that there are 150 million tons of plastic waste in the ocean and at least 8 million tons are flowing in the ocean annually.

YAMAMOTO is working on recycled jersey materials to reduce pollution of the ocean and to let more people to be aware of this issue.

It is estimated that the number of marina debris is going to exceeds the one of fish in 2050. YAMAMOTO will continue to work on solutions to conserve the beautiful ocean.

For Body and Earth
Since established in 1964, YAMAMOTO has been focusing on technologies for both eco-friendly and people-friendly materials.

The reason why YAMAMOTO has been committed to using Limestone Chloroprene Rubber (CR) is simply because our material comes into direct contact with human skin.
Unlike Natural Rubber, CR doesn’t contain latex which can cause serious allergic reactions.
It is all about safety and peace of mind.

YAMAMOTO will keep developing more sustainable and more safe materials.
