NHK showed a ribbon-cutting ceremony to mark the start of testing of the 170-meter tall turbine off Nagasaki Prefecture. A 100-kilowatt prototype had been placed in the same area in August 2012 as a test.

 

On the other side of Japan and far to the north, off the coast from the damaged nuclear reactor at Fukushima, a similar 2-megawatt turbine and a floating substation are expected to begin operation next month – followed by two 7-megawatt turbines before the end of 2015. That project’s leader, Marubeni, and its partners said earlier this month that it expected to commence operations in November.
