Seiko Epson
NEC had been the no. 1 personal computer vendor in Japan during the 1980s, but it faced increasing competition from Fujitsu, Seiko Epson and IBM Japan. Nevertheless, by the early 1990s, NEC was still the largest, having well over 50% market share in the Japanese market. Competition heated up later as rival Fujitsu started to aggressively market its computers, which were industry standard (x86) instead of NEC's indigenous models.
