NEC Corporation (日本電気株式会社, Nippon Denki Kabushiki gaisha; acronym for Nippon Electric Company) is a Japanese multinational conglomerate headquartered at the NEC Supertower in Minato, Tokyo. It provides IT and network services, including cloud computing, Artificial intelligence (AI), Internet of Things (IoT) platforms, and telecommunications equipment and software to businesses, communications service providers, and government agencies. NEC is one of the five largest defense contractors in Japan and a member of the Sumitomo Group.
From the 1980s to the 2000s, NEC was among the world's largest manufacturers of personal computers and semiconductors, but it has largely withdrawn from manufacturing since the early 21st century, spinning off its PC business to Lenovo and its semiconductor operations to Renesas Electronics and Elpida Memory. Today, NEC focuses on digital solutions, including AI software and services, with a notable history in Neural network research.
Early History and Founding
NEC was established on 31 August 1898 as Nippon Electric Limited Partnership by Kunihiko Iwadare and Takeshiro Maeda, using facilities purchased from Miyoshi Electrical Manufacturing Company. Iwadare served as representative partner, while Maeda handled sales. Walter Tenney Carleton represented Western Electric, which had an interest in Japan's phone market, and oversaw renovation of the Miyoshi facilities. The partnership was to be reorganized as a joint-stock company once treaty revisions allowed. On 17 July 1899, the revised Japan-US treaty took effect, and Nippon Electric Company, Limited was organized the same day, becoming the first Japanese joint venture with foreign capital. Iwadare was named managing director, with Ernest Clement and Carleton as directors, and Maeda and Mototeru Fujii as auditors. Management was shared among Iwadare, Maeda, and Carleton.
The company initially produced, sold, and maintained telephones and switches. The Mita Plant at Mita Shikokumachi was constructed in 1901 and completed in December 1902, modernizing production facilities. In 1903, the Japanese Ministry of Communications adopted NEC-supplied common battery switchboards, which powered subscriber phones and eliminated the need for permanent magnet generators. Switchboards were initially imported but produced locally by 1909.
NEC began exporting telephone sets to China in 1904. In 1905, Iwadare visited Western Electric in the US to study management and production control. Upon return, he replaced the subcontracting "oyakata" system with direct employment of managers and workers, removed production inefficiencies, introduced higher salaries with efficiency incentives, implemented new accounting and cost controls, and installed time clocks.
Between 1899 and 1907, telephone subscribers in Japan grew from 35,000 to 95,000. NEC entered the China market in 1908 under the Japan-China telegraph treaty and set up an office in Seoul in January 1908. Sales rose from 1.6 million yen in 1907 to 2 million yen in 1912, driven by expansion of Japan's phone service. However, in March 1913, the Ministry of Communications delayed a third expansion plan despite 120,000 potential subscribers waiting. NEC sales fell sixty percent between 1912 and 1915. To compensate, Iwadare began importing appliances such as electric fans, kitchen appliances, washing machines, and vacuum cleaners, which were novel in Japan. In 1916, the government resumed the expansion plan, adding 75,000 subscribers and 326,000 kilometers of toll lines, allowing NEC to expand while much of Japanese industry contracted.
Expansion and Early Technology (1919–1938)
In 1919, NEC began its association with Sumitomo, engaging Sumitomo Densen Seizosho to manufacture cables. NEC provided cable manufacturing equipment and transferred rights to Western Electric's duplex cable patents to Sumitomo Densen.
The Great Kantō earthquake of 1923 killed 140,000 people and left 3.4 million homeless. Four NEC factories were destroyed, killing 105 engineers and workers, and thirteen Tokyo telephone offices were destroyed by fire, disrupting service. In response, the Ministry of Communications accelerated programs to install automatic telephone switching systems and enter radio broadcasting. Initial automatic switching systems were Strowger-type models from Automatic Telephone Manufacturing Co. (ATM) in the UK. NEC participated in installations and became ATM's general sales agent. NEC developed its own Strowger-type automatic switching system in 1924, the first in Japan. The Mita Plant, nearly leveled in the earthquake, was rebuilt as a three-story steel-reinforced concrete structure starting in 1925, modeled after Western Electric's Hawthorne Works.
NEC entered radio communications in 1924, establishing a radio research unit. Japan's first radio broadcaster, Radio Tokyo, was founded in 1924 and began broadcasting in 1925 using NEC-imported Western Electric equipment. NEC began developing electron tubes in 1925 and produced its first 500 W radio transmitter by 1930. In 1934, it supplied a 100 kW radio broadcasting system to China's Xinjing station.
In 1928, NEC-developed photo-telegraphic equipment transmitted photos of Emperor Hirohito's accession ceremony in Kyoto. Competing newspapers Asahi Shimbun and Mainichi Shimbun both adopted the NEC product due to its faster transmission and higher picture quality, over alternatives from Siemens and French manufacturers. In 1929, NEC provided Japan's Ministry of Communications with the A-type switching system, the first such system developed in Japan, and also supplied nonloaded line carrier equipment.
Post-War Diversification and Computing
After World War II, NEC diversified into computing and electronics. In the 1950s, it began developing computers and semiconductor technology, leveraging its telecommunications expertise. NEC introduced its first computer, the NEAC 1101, in 1958, and later became a major supplier of mainframe computers in Japan.
During the 1960s and 1970s, NEC expanded into integrated circuits and microprocessors, becoming a leading semiconductor manufacturer. It also entered the personal computer market in the 1980s with the PC-8000 series, which dominated the Japanese market. NEC's PC-98 series became a standard in Japan for over a decade.
In the 1980s, NEC was one of the world's largest semiconductor producers, ranking among the top three globally. It also developed early Neural network hardware and software, contributing to Machine learning research. NEC's laboratories conducted pioneering work in pattern recognition and neural computing, laying groundwork for later AI applications.
