History

Fujitsu Laboratories traces roots to postwar computing efforts linked to Fujitsu, the development of mainframes at locations such as Kawasaki, Kanagawa, and research collaborations with institutions like University of Tokyo, Keio University, and Tokyo Institute of Technology. During the 1970s and 1980s it engaged with companies such as IBM, Hitachi, NEC, and Toshiba on hardware and system design, while participating in standards discussions with bodies like IEEE, IEC, and ISO. In the 1990s the lab expanded into networking and Internet technologies interacting with organizations such as AT&T, NTT, and Cisco Systems, and contributed to initiatives aligned with projects from DARPA and research funded by METI (Japan). The 2000s saw growth in optical networking and semiconductor research collaborating with NTT DoCoMo, Sony, Panasonic, and Renesas Electronics. More recent decades connected the lab to cloud computing and AI developments alongside Microsoft Research, Google Research, Amazon Web Services, and research programs related to RIKEN and Japan Science and Technology Agency.
