シンシア Company Overview

Cynthia is next to the company. With a sincere heart, Cynthia continues to make endless efforts and challenges.

Sincere Co., Ltd. was established on April 1, 1992, as the second company of the Toyoyo Group, and on August 1, 2004, it changed its name to Sincere Co., Ltd., challenging new possibilities. Living up to the new name "Sincere," which means "honesty," we strive for endless effort and evolution in the field of human resource support, aiming to be a company that continues to take steps forward with sincerity and contributes to society. As a local company in Oita Prefecture, the Toyoyo Group (originating from Toyoyo Seiko Co., Ltd.) has been advancing in manufacturing since its establishment in 1977. With the spirit of "emphasis, responsibility, and compassion" held by each employee, it is a corporate entity that contributes to the company. Inheriting this spirit, Sincere Co., Ltd. also seeks better, more reliable, and faster services in the manufacturing field, continuing to make endless efforts under the corporate philosophy of "sincerity, effort, and challenge." We are now thinking of and providing new services that companies require.
