Top Message Message from the President
Yamakyu expanded to Nagahama on June 6, 1931, by its founder, Yoshizaburo Hirayama. Since then, for about a
century, we have developed a business that is closely tied to the local community as a trading company
specializing in machine tool parts. We have established an integrated system from the installation of
mechanical equipment to plumbing and electrical work, targeting six locations in Shiga Prefecture from our
hometown of Nagahama, and the neighboring Ogaki City in Gifu Prefecture, and have received high praise from
many customers for our compliance (legal compliance). It has grown by the time I receive it. Furthermore, in
2014, we expanded into Thailand as our first overseas base. We aim our perspective broadly to the world.
Although we have built our position as a glocal specialty trading company with a global perspective and
local ties, we also respond sensitively to changes in the times. For example, actively promoting DX is one
example. Yamakyu responds quickly to this global trend. We have newly formed a DX Promotion Office and are
contributing to productivity improvements through online support and operational efficiency through the
introduction of RPA.
We also take the initiative in confronting environmental issues, which are global issues. Starting with environmental ISO 14001 certification in 2001, and energy ISO 050001 certification, we are also promoting unique initiatives befitting a company originating from Omi, which is responsible for Lake Biwa.
In 2031, Yamakyu will finally celebrate its 100th anniversary. With this major turning point in front of us, we must imagine the future while confronting the times.
For this reason, the ``MIRAI Project'' has been launched with a focus on young people who will lead the next generation. Please look forward to the future of Yamakyu.
