Fujitsu is the second oldest IT company after IBM and before Hewlett Packard, established on June 20, 1935,[7] under the name Fuji Telecommunications Equipment Manufacturing (富士電気通信機器製造, Fuji Denki Tsūshin Kiki Seizō), as a spin-off of the Fuji Electric Company, itself a joint venture between the Furukawa Electric Company and the German conglomerate Siemens which had been founded in 1923. Despite its connections to the Furukawa zaibatsu, Fujitsu escaped the Allied occupation of Japan after the Second World War mostly unscathed.

In 1954, Fujitsu manufactured Japan’s first computer, the FACOM 100 mainframe,[8][9] and in 1961 launched its second generation computers (transistorized) the FACOM 222 mainframe.[10] The 1968 FACOM230 “5” Series marked the beginning of its third generation computers.[11] Fujitsu offered mainframe computers from 1955 until at least 2002[12] Fujitsu’s computer products have included minicomputers,[13] small business computers,[14] servers[15] and personal computers.[16]
