Hibikinada Offshore Wind Farm
５➢ Kitakyushu City launched the Green Energy Port Hibiki concept in 2010 topromote the accumulation of wind power generation-related industries.

Yamaguchi➢ The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) revised
the Port and Harbor Law in 2016, and Kitakyushu City became the firstKitakyushu
city in Japan to set up a public bid for occupancy of offshore areas for
20 years (the first project under the revised law).
Fukuoka➢ As a result of a public solicitation, the consortium led by Kyuden Mirai
was selected as the business operator, and a basic agreement wassigned with Kitakyushu City on January 10, 2018.
