2 MW, 23 turbines (74%) are commercial or local government owned all of them are very closed to seashore, so-called Semi- Offshore . Dolphin type or Monopiletype foundations are used at these projects. Real Offshore projects (more than 1km from seashore) are National type by NEDO : MM, 2 turbines at Choshiand at Kitakyusyu(Gravity type) (Jacket type foundation) Floating type by MOE : 2 MW, 1 turbine at Kabashima(Spar type floater)(GOTO-FOWT) ItgrantedtoGotocity,relocated 10km southeast to Fukue-island, reconnected to grid, and started commercial operation in Apr. 2016.

Restrictedshallowsea area (surrounded by deep sea) Floating wind Power for deepsea by national projects were very expensive. Poor grid infrastructureat good wind area (Hokkaido & Tohoku, northern Japan ) Moderate wind speed (Low income) at Offshore area in central & western Japan Big law uncertainty at General common sea area (So-calledThomasHobbes s the war of all against all.)
