"Tateho's vision of creating new environment-friendly materials"

Tateho Chemical Industries Co., Ltd. was born in the town of Ako--an area blessed with a warm climate and the abundant marine resources of the Inland Sea of Japan.
The history of the salt industry in Ako is long--dating back nearly 1300 years to the Nara period.
In 1966, Tateho was established as a group of engineers seeking to provide new materials widely useful for society by putting this inherited, time-honored wisdom into full use, and by effectively utilizing bittern, a substance left after separating salt from seawater.
Since then, we have continued to provide the world with highly functional products--including magnesium oxide, magnesium hydroxide, electrofused magnesium oxide, single crystal magnesium oxide, flame retardants, and ceramics--by expanding our businesses on the basis of our proprietary crystallization control technology.
We are committed to contributing to industry worldwide under the slogan of "Aiming to be a development-oriented company friendly to the natural environment and leading the world with proprietary technologies" by continuously adhering to our environmental policy and further improving our proprietary technologies.
