Recruitment Information

We are a truly friendly working environment.

Each person has their own lifestyle, such as family structure and upbringing. Providing the same company benefits for employees who have different lifestyles does not necessarily create an easy environment for employees to work in. Sanyu Giken adopts creative company benefits that are customized to each individual.
We believe that the company should change to enhance the employee's individual life.
This includes adopting flextime work and work-from-home policies, providing single parent allowance, allowing casual attire, enabling fertility treatment leave, providing family celebration gifts, and offering overseas study trips. We reform our benefits every year. Instead of changing work styles, we aim to reform the motivation to work. We want our employees to work with the goal of "growing.” We are confident that this employee growth will lead to our company's growth. Come join us to grow together with new working methods like none other. * Japanese page only.
