Iwatsu Electric

Iwatsu Electric, Co., Ltd. (岩崎通信機株式会社, Iwasaki Tsūshinki Kabushiki-gaisha) TYO: 6704 is a Japanese electronics manufacturer founded 14 August 1938.

Iwatsu Electric is a member of the Mitsubishi UFJ Financial Group (MUFJ) keiretsu.

Originally starting up as a telephone manufacturer, Iwatsu had been a longtime supplier to the public Nippon Telegraph and Telephone company. The company has enjoyed growth along the public NTT, expanding its products to radio communication equipment, oscilloscopes, and in the year 1961, their first reprographic system.

Seiichi Iwasaki was born in 1895 in Shimane, Japan. As a teenager, he moved to Tokyo without his family. He worked by day to support himself and went to school by night. Whilst in school, he became the leader of a circle of like-minded friends, which they called Hatenkai. Together, they vowed to succeed in the future.

Iwasaki dropped out of school in 1912 and began his military service in 1913 in Okayama—which he completed in three years. Then he moved to Hokkaidō where he started his career as an entrepreneur. His ventures in Hokkaidō stretched from railroads to coal mines, until the year 1933 when he changed his course and came back to Tokyo again.

Seiichi Iwasaki was running a small business called Iwasaki Kogyo in the Yoyogi neighborhood of Tokyo for manufacturing and selling cables. Iwasaki realized that in order to stay in business, he needed to follow the national policy and produce what the country needed at the time.

The first focus was on anti-induction telephones. In the 1930s, the telephone infrastructure in Japan was primarily used by the railroad industry, the police, the utility industry and the mining industry. The telecommunications infrastructure was so poor that it had to rely on power lines and railway cables—upon which telephone signals were superimposed. Because the telephone signals were susceptible to inductive interference and noise and the defective wiring in the long lines caused too much signal loss, normal telephone conversations were difficult. Iwasaki Kogyo set out to develop an anti-induction telephone to solve this problem, whilst running the cable manufacturing operations. Similarly, Iwasaki Kogyo focused on secure, anti-tapping telephones.

Motivated by these opportunities, he started looking for engineers. Luckily he knew engineers from the members of Hatenkai: Minoru Tokoha and Motosaburo Hashimoto. When he talked to them, they both showed strong interest. With the help of these two engineers, he set up a lab in his own house in Yoyogi to develop the two kinds of special-purpose telephones.
