Office buildings

In Japan, 1969 was the dawn of the nation’s high-rise office building period. This began with the Kasumigaseki Building, and power equipment would be essential in these buildings as they aimed to reach new heights one after another. Office buildings would continue to evolve with optimal electrical systems. We were responsible for the building’s construction from its design.
