Energy Plant
Construction

Using expertise and mobility
developed from over 30 years of experience to meet our customers’ every need

Our energy plant construction business provides the specialized electrical instrument work
necessary during routine inspections of power stations, as well as for massive refrigeration machines that can cool entire buildings.

We are also particularly well-versed in the installation of electrical instruments used
with pressurized water reactors (PWR) and pump vibration measurements.

Meanwhile, our nuclear power plant division boasts field experience
at major plants such as the Takahama and Oi Nuclear Power Plants, and the Rokkasho Reprocessing Plant.

Energy Plant Branch Construction Manager

Ryuji Sugihara

The strength of our energy plant construction business comes from our over 30 years in the field, spanning back to the initial period in which so many of Japan’s nuclear plants were first built. Our established position in the field means that our engineers are bona fide veterans who possess the skills and experience to handle even the most challenging (A Rank) jobs. Our branches located throughout Japan also provide us with a mobility advantage, enabing us to gather the necessary professionals from throughout the nation and bring them to where their skills are needed. This nationwide network allows us to use our experience and skills to not only service the electrical equipment at nuclear power plants, but to also assist with a wide variety of our customer needs such as thermal power plant maintenance and interior construction. We will continue to maintain and improve our superior skills and excellent personnel, and apply them not only to energy plant construction, but also new fields of work in the future.
