The Nippon Ham Fighters announced on December 19 that they created a joint task force with parent company Nippon Ham that will be responsible for conducting research into the logistics of building a new stadium. The Fighters are currently accepting proposals for the Hokkaido area. They are hoping to lighten the financial burden and strengthen community ties by involving as many local governments and businesses as possible. They plan to set a course of direction by March 2018.
