The company installed a single 2.4MW turbine about 3km off the coast from Choshi city, Chiba prefecture.

Japan’s New Energy and Industrial Technology Development Organisation (NEDO) funded two-thirds of the 3.5bn yen ($43m) in project costs, with the remainder put up by Tokyo Electric Power (TEPCO).

The turbine, installed with fixed foundations, will be connected to the TEPCO grid in January 2013 using underwater cables.
