Relationship between
Fullheart Japan and Harvest Japan

Daisan Denki Co., Ltd (predecessor of Fullheart Japan), founded in 1968 for wiring assembly of electronic devices in Ota Ward, grew through design and production of industrial computer control equipment. In 1991, the company name changed to Fullheart Japan, and Harvest Japan more specialized in sheet metal working and wiring assembly of electronic devices was also founded. Both companies are like a family and create the synergy as “one company”, taking advantage of the strength of both companies. We will continue to respond to various customer needs utilizing advantages of both.
