The story

The company was founded in 1949 upon chemical water treatment business (boiler water treatment chemicals). The founder of the company, Haruo Kurita, who had previously served in the Japanese navy, started selling boiler water treatment chemicals based on the navy boiler technology.

In 1951 Kurita entered into water treatment facilities business and established its first R&D center. Two years later the company expanded their offering by starting the chemical cleaning business while 1958 saw Kurita expanding their maintenance services. In 1961 the company was listed on the second section of the Tokyo Stock Exchange and the Osaka Securities Exchange and a year later the company stock was listed on the first section of the aforementioned stock exchanges.

By 1962 the company established its second R&D center which resulted in expanding their product line by adding new chemical products for process treatment.

In 1973 Kurita forayed into the electronics industry and in the 1980s established a third R&D center and deployed a tool cleaning business.

The company's soil remediation business was launched in 1991 and ten years later, in 2001, the company started offering consulting services for hedging soil pollution risks. Land Solution Inc., a Kurita subsidiary, was established as a consulting company dealing in soil remediation. 2002 saw the launch of ultrapure water supply business and in 2004 Kurita entered the Chinese market by establishing Kurita Water Industries (Suzhou) Ltd. A year later a fourth R&D center, the Kurita Global Technology Center, opened in Nogi, Tochigi.

Focusing on growth, the company acquired the Water, Paper and Aluminum compounds business from BK Giulini and founded Kurita Europe APW GmbH.
