In order to be sure there is vast offshore wind energy potential on the Japanese coastal areas, we observed offshore wind climate on the Pacific Ocean near Fukushima pref. And to use the energy, we developed offshore wind power generation systems. At first, this paper presents the observation result that shows wind climate characteristics are good for wind turbines as well in Europe. Also, we developed two types of offshore wind power generation systems, one is installed on seabed and another is floated on water. And both can be safe from Japanese severe natural conditions.
