Abstract: In Japan, the cumulative capacity of wind turbine generation systems on land has increased steadily in recent years. To install a large number of wind turbines has inherent problems such as shortage of suitable land, and inadequate infrastructure such as power cables and roads. The necessity for development of offshore wind turbine generation systems has been recognised based on the above backgrounds. An expert committee to survey the prospect of offshore wind turbine generation in Japan was organised last year. In this paper, the prospect of offshore wind energy development in Japan is reported based on the discussion in the committee. As a result, it was found that there are some undesirable circumstances for offshore wind energy utilisation in Japan. For that reason, we need technological innovation as well as an increase in scale of wind farms in order to achieve an economical profit. The difficulty in realising of offshore wind farms in Japan relates to Japanese inshore conditions, various legal regulations and fishing rights issues.

Keywords: Japan; offshore wind energy; resources; development.
