The Nishihara Group's founder, Shuzo Nishihara, was born in Tokyo on August 25, 1883, and founded a company that specialized in sanitation work that was unique in 1917. Later, the company enlarges achievements smoothly, Shuzo visited sewage treatment plants in Europe and the United States in 1927. He also frequently visited libraries in London, deepening his knowledge nearly a year. After returning to Japan, he worked on the development of equipment from digestion tests of night soil, while also constructing wastewater treatment plants at U.S. military facilities on an exclusive basis upon the request of the U.S. military. In that way we have established a foundation for wastewater treatment.
　In 1955, we also succeeded in promoting the digestion of night soil, which we had been working on for a long time. In several years, we constructed night soil promotion digesters in more than 30 cities, including Muroran City. Since then, we have also worked on high concentration organic wastewater treatment from the factories of foods industry in the private sector, and even now, more than half a century later, those factories are still important customers of Nishihara Neo.
　As stated above, our founder learned about “the night soil treatment and the high concentration wastewater treatment from the factories of foods industry” which had hardly known in Japan in the first half of the 20th century by himself from many experiments. Even though it was a private company, he sometimes conducted those treatments in the form of a volunteer. He was truly a pioneer in this field. At the same time, he made Nishihara widely known to the public as the only leading company.
　Nishihara Neo have been working on wastewater treatment by biological method as our core business, which is the essence of our founder. Moreover we are expanding the scope of business to physicochemical treatment in recent years.
　Nishihara Neo has also inherited its founder's overseas orientation, and is utilizing its domestic technologies and expertise in Southeast Asia to contribute to the improvement of the water environment, while also recruiting a wide range of human resources.
　I will strive for further development by sharing with our employees the responsibility and fulfillment of succeeding our great founder's business as well as its sense of happiness.
