IWGP Junior Heavyweight Championship
From August 5, 1996, until November 5, 1997, the title was part of the J-Crown, or J-Crown Octuple Unified Championship. The J-Crown was an assembly of eight different championships from several different promotions. It was created on August 5, 1996, when The Great Sasuke won an eight-man tournament. The IWGP Junior Heavyweight Championship, the British Commonwealth Junior Heavyweight Championship, the NWA World Junior Heavyweight Championship, the NWA World Welterweight Championship, the UWA World Junior Light Heavyweight Championship, the WAR International Junior Heavyweight Championship, the WWA World Junior Light Heavyweight Championship, and the WWF Light Heavyweight Championship were the eight championships that were involved. On November 5, 1997, then-champion Shinjiro Otani vacated all J-Crown belts but the IWGP Junior Heavyweight Championship after the World Wrestling Federation (WWF) retook control of its Light Heavyweight title, effectively ending the J-Crown.
