Message from Top Management

  • 代表取締役社長 山口幸太
  • In the 40 years since our founding in 1969, our company's progress has been resolute and steady, based on a foundational value of people, harmonious relations, and bonds of trust.
    Built upon our solid foundation of human-to-human relationships, we were able to make it to this present day. We would like to once again express our deep respect and gratitude to our clients and business partners who have supported us.
    Our work supports electric railways, an indispensable foundational service for daily life, and it is therefore our important duty to carry out our work safely and reliably.
    To that end, we strive to diligently observe and provide appropriate guidance and training to our employees, to not only nurture advanced technical skills, but also necessary qualifications, to foster pride and compassion in their work.
    "People have intrinsic value." Each individual is an asset, not only a resource, to a company.
    While evolving to meet the needs of this diversifying generation, we hope to uphold the sense of "duty, empathy and gratitude" and nurture humility by sharing our founder's starting point and wholehearted desire to be a company that serves and is needed by society.

    Thank you very much for visiting our website.
    We wish you good health and happiness.
