Abstract
Since the wind turbine system comprises many parts and components from various manufacturers, the facts of the Japanese wind industries had not been clear for a long time. Recently the Japanese government is considering the promotion of wind turbine industries from the view point of global warming prevention and accelerates wind turbine’s installations in Japanese severe environmental conditions. Several statics have been done about wind industries by eminent organizations. Local component suppliers and system integrators are expected to play key roles in domestic production of wind turbines suited to local environmental conditions. This paper aims at gathering information and showing analytical results of the researches performed by JSIM, JEMA, JCRE, etc. to find out proper strategy for Japanese wind turbine industries.
