History of Fujitsu
Introduction
Fujitsu Limited is a Japanese multinational information and communications technology (ICT) company. It is one of the world’s oldest and most influential technology firms, known for its contributions to computing, telecommunications, semiconductors, supercomputers, and IT services.
Fujitsu is headquartered in Tokyo, Japan, and has played a major role in the global development of information technology.
Origins and Foundation (1923–1930s)
Fujitsu was founded in 1923 as a spin-off from Furukawa Electric Company, one of Japan’s major electrical manufacturers.
Original name: Fuji Electric Manufacturing Co., Ltd.
The name Fujitsu comes from “Fuji Tsūshin” (Fuji Telecommunications).
In 1935, Fujitsu became independent from Fuji Electric and officially established itself as a telecommunications equipment manufacturer.
Early focus areas:
Telephone equipment
Telegraph systems
Communication technologies
Post-War Recovery and Growth (1945–1960s)
After World War II, Japan focused on rebuilding its industrial base, and Fujitsu became a key player in modernizing the country’s communications infrastructure.
Major developments:
Entered the computer industry in the 1950s
Produced Japan’s first domestically made computers
Expanded research in electronics and semiconductors
In 1954, Fujitsu developed FACOM 100, one of Japan’s earliest computers, marking its transition from communications to computing.
Expansion into Computing & Semiconductors (1960s–1980s)
During this period, Fujitsu emerged as a global technology company.
Key milestones:
Development of mainframe computers
Strong presence in enterprise computing
Major investments in semiconductor manufacturing
Collaboration with international firms (e.g., IBM-compatible systems)
Fujitsu’s FACOM series of mainframes became widely used by:
Government agencies
Banks
Large corporations in Japan
By the 1980s, Fujitsu was:
