Made in 1925 (Taisho 14)

West of Nagata lies the Takeno River power station, which generates hydroelectric power. It was the first electric power facility on the island, constructed in 1926 (Taisho 15), by the Yakushima Electric Corporation. It brought power to the villages of Nagata, Yoshida, and Issou. Fast-forward to the 1950s, and the demand for electricity had skyrocketed. A lone power station was no longer sufficient, and thus the power supply of Miyanoura, established by Yakushima Denko Electric Company, was extended to this area of the island as well.

At Takeno River Power Station, up to 150kW of power can be generated by river’s kinetic energy spinning the station’s water turbine. The equipment exhibited here, through careful tending and repair, was used for 65 years straight—since the station’s inception, and until it was replaced in 1991 (Heisei 3). Nowadays, it remains a valuable piece of history, and was donated to Nagata village by the Kyushu Electric Power Company.
