The Ministry of Economy, Trade and Industry (METI) and the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) announced July 30, 2019, that they have designated four areas as "prospective areas" for wind power generation.
The four areas are located off the coasts of (1) Noshiro City, Mitane-cho and Oga City (Akita Prefecture), (2) Yurihonjo City (Akita Prefecture) (north and south sides), (3) Choshi City (Chiba Prefecture) and (4) Goto City (Nagasaki Prefecture), respectively. And wind farms will be developed in those regions prior to other regions.
The four areas were designated as "promotion areas" based on the "Law for the Promotion of Special Sea Areas Used for Power Generation Using Renewable Energy" (also known as "New Offshore Law").
The ministries selected 11 areas that have already been prepared for wind power generation to a certain extent and designated four of them as "prospective" because environments for wind power generation (e.g. agreement with local communities) have been advanced in the four areas. They will start preparations for wind/geological condition researches by councils, the Japanese government, etc soon.
In addition to the four areas, seven areas have been prepared to a certain degree. They are (1) an area off the coast of Happou-cho and Noshiro City (Akita Prefecture), (2) area off the coast of Katagami City (Akita Prefecture), (3) the Sea of Japan off the coast of Aomori Prefecture (north side), (4) the Sea of Japan off the coast of Aomori Prefecture (south side), (5) Mutsu Bay (Aomori Prefecture), (6) area off the coast of Murakami City and Tainai City (Niigata Prefecture) and (7) area off the coast of Enoshima (Saikai City, Nagasaki Prefecture).
The areas that were not designated as "prospective areas" this time might be designated as "prospective areas" in the next fiscal year or after that.
For each area, the two ministries also wrote notices regarding future processes by, for example, saying that there are needs for (1) environments including agreements with local communities, (2) negotiations with interested parties and (3) arrangements for preventing world heritages from being affected.
