    Introduction our senior staff

    • I have been making machines every day for over 40 years because I enjoy this job.

      Masamichi Yokoyama

      Of course, the product types are constant, but no two products are the same. I carefully build each and every machine, thinking, "what I have built will enrich someone's life somewhere in the world." The process of making a machine is fun, but I also enjoy imagining where and how my creations will be used.

    • Before joining Koritsu,
      I was working as a machine
      maintenance worker.

      Nakahara Masayuki

      Not everything was new to me, but I did not have much experience in welding, which was my main job and I couldn’t perform well in the beginning. Thanks to Mr. Yokoyama’s thorough guidance, I was able to become a full-fledged technician and was entrusted with tasks. My current goal is to become a person like Mr. Yokoyama, who builds machines with exceptional skills and is humorous and friendly.
