Tsukishima Kikai was founded as Tokyo Tsukishima Kikai Seisakusho in 1905 in a place in Tokyo known today as Tsukishima 4-chome, Chuo-ku, Tokyo. The Tokyo Factory began as a small factory with fewer than 20 employees. Japanese industry at the time relied on manufacturing machinery and equipment imported from overseas. We were among the first to succeed in the domestic production of sugar production machinery and ammonium sulfate production equipment. As our business grew, we branched out into chemical textiles and salt production fields.
At the time of the Company’s founding, the factory was powered by steam engines. Electricity had yet to reach the Tsukishima area.

As Japan’s industrial structure underwent a massive shift from light to heavy industry, we, too, advanced into the heavy and chemical industries, including aluminum and magnesium. We built the new Tsurumi Factory in Yokohama’s Tsurumi-ku to enhance and modernize our production facilities. As we evolved into a manufacturer of equipment for the chemicals, machinery, and iron and steel fields, during the 1960s we ventured into the water purification and sewage treatment field, contributing to the expansion of Japan’s water infrastructure by manufacturing a broad range of water purification and sewage treatment facilities.
Miraculously spared damage in World War II, the Tsurumi Factory supported Japan’s postwar recovery and rapid economic growth.

Due to rapid growth after entering the water purification and sewage treatment field, the Tsurumi Factory reached the limits of its production capacity. In response to demand for larger products, we built the Ichikawa Factory in the waterfront area of Ichikawa City, Chiba Prefecture. Equipped with modern manufacturing facilities, the factory was capable of shipping large products by sea. From this point forward, we would contribute to industrial development and environmental protection not just in Japan, but globally, exporting products around the world.
In 1985, we expanded our manufacturing capacity still further with the addition of Factory No. 2, which focused mainly on the assembly of equipment.

Seeking to further increase production efficiency, we relocated our manufacturing functions to the Muroran Factory and introduced state-of-the-art machinery. The factory is located on the site of the Muroran Plant of Japan Steel Works M&E, Inc. and ships large products by sea from the wharf facilities of Japan Steel Works M&E, Inc.
