Mixed martial arts superstar Demetrious “Mighty Mouse” Johnson will make his ONE Championship debut in Japan against Yuya Wakamatsu, the organization announced on Thursday.
The bout was one of the first six announced in a release for ONE's first-ever event in Japan, which is set for March 31 at Ryogoku Kokugikan.
Johnson, a former UFC flyweight champion who was named the top fighter of 2017 by Bleacher Report, Bloody Elbow and at the ESPY Awards, moved to ONE from UFC in October.
