The project, to be built off the coast of Shimonoseki city in Yamaguchi prefecture, will use 20 turbines and may cost as much as 25 billion yen ($320 million), Kozo Domori, a Maeda spokesman said today by phone.
The wind farm will be built in two stages, with the first 10 turbines starting operation in April 2016 and the remaining the following year, he said.
The company is seeking investors for the project that is expected to earn about 3.5 billion yen a year from electricity sales when completed, Domori said, confirming an earlier report by the Nikkei newspaper.
