Business Overview

Tosei Systems Co., Ltd. is a wholly owned affiliate of Tokyo Seimitsu that supports Tokyo Seimitsu's product development in terms of software.

Focusing on Tokyo Seimitsu's semiconductor manufacturing equipment and measuring equipment, as well as equipment of affiliated companies, we perform development and maintenance of embedded software that controls equipment and Windows applications incidental to equipment. We are also involved in development and operational support for enterprise resource planning (ERP) systems and the creation and maintenance of web sites, and undertake wide-ranging software operations for entire Tokyo Seimitsu Group. We conduct new graduate and mid-career recruitment of men and women from different academic backgrounds according to aptitude for software, enabling us to handle a wide range of software-related work. We are making efforts toward education for new graduates, employing a mentor system that tracks prospective employees as well as four-month training, including external training, after employees join. The final curriculum item in external training is a team development project using microcomputer boards. Participants are able to gain an overall view of on-site development, from requirements definition to design, production, and presentation of results. We work to ensure that new graduates are able to get off to a confident start at where they are assigned following training.
