A wind power field test was first conducted in 1995 in Japan. In 2001, wind power plants were built in 31 areas with differing local conditions. Operational data are being collected. Ficed by NEDO, field tests are conducted with industry every year. In 2013, a first offshore floating wind farm demonstration project (at most 14 MW) started operation in Fukushima; the wind farm still operates as an empirical research project with a view to further expanding offshore wind power.
