The G80 2MW turbine at the JFE Engineering wind project near Chinzei, in the Saga prefecture on the island of Kyushu, caught fire around 3pm on 21 August, and burned for roughly 16 hours before being extinguished.
The turbine is located just 800 metres across a body of water from the Genkai nuclear power plant, and debris was seen to fall from the 30-metre-high tower, Japanese news station Saga TV reported, among others.
No injuries were reported. So far, no cause has been given for the fire, with police and fire crews investigating.
A spokesman for Siemens Gamesa Renewable Energy said the manufacturer was supporting the wind farm owner in the investigation into the cause of the fire.
It is the second time a turbine in the area has been damaged by fire. One caught fire during commissioning in August 2004, when a brake applied during a typhoon produced sparks resulting in a fire in the nacelle, said Yoshinori Ueda from the Japanese Wind Power Association.
