Jushin Liger
In 1987, Hart branched out to Japan where he wrestled for New Japan Pro-Wrestling (NJPW) on several tours. In NJPW, he wrestled Keiichi Yamada, both before and after he debuted the Jushin Liger gimmick. On May 27, 1988, Hart defeated Hiroshi Hase for the IWGP Junior Heavyweight Championship, becoming the first non-Japanese wrestler to win the title. His reign would end nearly a month later, as he lost the title to Shiro Koshinaka on June 24, 1988.
