Our history

Immediately after the war in 1947, when the city was still recovering, the factory was established by Matsushima Ryohei on the rubble of a salt field in Takamatsu, Japan with only a handful of employees. In 1950 while witnessing poverty at the Osaka Port during the Great Depression, Matsushima Yoshio, who later became Kyowa’s first president, swore “It is wrong that people have to endure such hardship. We must provide opportunities for our employees and their families! We must succeed!” This determination and spirit fuelled the start of a pilot plant that produced Magnesium Oxide and Magnesium Hydroxide.   

In 1951, resources and equipment were difficult to obtain. At that time, sake barrels were scarcely being used by the breweries. Intuitively, Kyowa (which would later become known as Kisuma) determined that the sake barrels could be used as tanks for raw materials. These became the first tanks used as storage for bittern.  Consistent production growth proved to Mr. Matsushima that Kyowa could be a successful and sustainable business. 

On Thursday, September 17, 1952, Kyowa Chemical Industry Co., Ltd. was officially established.
