Electrical Services in Japan
Electricity powers everything from neon-lit Tokyo streets to traditional homes in rural prefectures. Japan operates on a complex electrical system with two different frequencies—50 Hz in eastern Japan and 60 Hz in western Japan—making professional electrical work both technically demanding and highly regulated.
