In 1956, after postwar reconstruction was completed, an economic white paper declared that "the post-war era was now over," and marked the birth of an industry that would later become TACMINA. The founder Toshio Yamada is originally from Ikuno-cho, Asago City (formerly Asago-gun) located in Hyogo Prefecture. At that time, the waterworks had not been developed yet in the area and infectious disease spread due to contamination of the drinking water. Mr. Yamada, who was working at a local company, thought that there must be a way to help improve the health and safety in the community and decided to set up his own business. He set up a factory at his home and started manufacturing and selling chlorine disinfection equipment.

Launched in 1965, the "N-Feeder S-Type" was the first electrically-powered metering pump made in Japan. This pump would become the foundation of TACMINA as a manufacturer of metering pumps. At that time, the only electrically powered metering pumps available were imported, extremely expensive and hard to come by. The N-Feeder S-Type developed by TACMINA also met the needs of other emerging applications during this period, as it became necessary in pool maintenance equipment for elementary and junior high schools. TACMINA pumps became the first choice for injecting chemical solutions and chlorine disinfection equipment. TACMINA earned high praise from many respected organizations, being the first product recommended by the Japan Food Hygiene Association, the Japan Small Scale Water Works Association and the Japanese Society of School Health.

The living standards in Japan had improved due to rapid economic growth. As a result, the rivers became contaminated by industrial waste. Water and pollution problems became more serious as evidenced by Minamata disease and cadmium poisoning. The "Water Pollution Control Act" was enacted in 1970 to accelerated and improve pollution control measures. Treating industrial waste water created a variety of needs during this period. This enabled TACMINA to add various related equipment to its product lineup, such as measurement instruments (pH meter), dryers, agitators, etc. TACMINA combined this pump with other devices to help create complete solutions to solve issues that our customers faced. TACMINA producing one system after another, including the "pH neutralizer and recorder system" and an "Intra-tubular continuous pH control system."
