## The junior heavyweight division
The championship anchors NJPW's junior heavyweight division, a weight class for wrestlers below 100 kg (220 lb).[2](https://puroresurepresentin.wordpress.com/new-japan-pro-wrestling/iwgp-junior-heavyweight-championship-history/) Because the division is smaller than the heavyweight ranks, the title is classified as a secondary championship in NJPW's hierarchy.[1](https://www.thesmackdownhotel.com/title-history/njpw/iwgp-junior-heavyweight-championship) The division has long served as an international showcase: the title has been defended in the United States and Mexico in addition to Japan,[2](https://puroresurepresentin.wordpress.com/new-japan-pro-wrestling/iwgp-junior-heavyweight-championship-history/) and foreign competitors have held it, including [Owen Hart](https://www.edgepedia.org/owen-hart) in 1988, [Chris Benoit](https://www.edgepedia.org/chris-benoit) under his Pegasus Kid persona in 1990, and later luchadors such as Ultimo Dragon, Juventud Guerrera, and Mistico.[4](https://www.wrestling-titles.com/japan/newjapan/iwgp-j.html)
## Early history
The title was decided in a nine-man tournament on February 6, 1986, in which Koshinaka defeated The Cobra, a wrestler who had vacated the NWA World and WWF junior heavyweight titles the previous year.[4](https://www.wrestling-titles.com/japan/newjapan/iwgp-j.html) The first reigns traded between Koshinaka, Nobuhiko Takada, Kuniaki Kobayashi, and Hiroshi Hase; Koshinaka's second reign ended when he vacated the title on August 2, 1987 because of a leg injury.[4](https://www.wrestling-titles.com/japan/newjapan/iwgp-j.html) • [2](https://puroresurepresentin.wordpress.com/new-japan-pro-wrestling/iwgp-junior-heavyweight-championship-history/) Owen Hart won the title from Hase on May 27, 1988 in Sendai, and Koshinaka regained it less than a month later in Osaka.[4](https://www.wrestling-titles.com/japan/newjapan/iwgp-j.html)
Jushin Thunder Liger (Keiichi Yamada) won the title for the first time on May 25, 1989, beginning a record association with the championship.[4](https://www.wrestling-titles.com/japan/newjapan/iwgp-j.html) Across the following two decades he held it eleven times, and the title changed hands repeatedly in tournament finals and at NJPW's January 4 [Tokyo Dome](https://www.edgepedia.org/tokyo-dome) shows.[4](https://www.wrestling-titles.com/japan/newjapan/iwgp-j.html)
## The J-Crown episode
In 1996 the title was folded into the J-Crown, an octuple crown in which one wrestler simultaneously held eight junior heavyweight championships from different promotions; The Great Sasuke defeated Ultimo Dragon in the J-Crown tournament final on August 5, 1996, in Tokyo, to become the octuple crown champion while holding the IWGP title.[4](https://www.wrestling-titles.com/japan/newjapan/iwgp-j.html) • [7](https://lastwordonsports.com/prowrestling/2018/04/14/belt-collecting-the-legend-of-the-j-crown-championship/) The arrangement ended on November 5, 1997, when then-champion Shinjiro Otani vacated all of the J-Crown belts except the IWGP Junior Heavyweight Championship after the World Wrestling Federation retook control of its Light Heavyweight title, effectively ending the J-Crown.[5](https://prowrestling.fandom.com/wiki/IWGP_Junior_Heavyweight_Championship)
## Relationship to the Best of the Super Juniors
The title is closely tied to the [Best of the Super Juniors](https://www.edgepedia.org/best-of-the-super-juniors), an annual round-robin tournament NJPW has held since 1988 to spotlight the junior heavyweight division.[3](https://www.thesmackdownhotel.com/tournaments/njpw-best-of-the-super-juniors) • [6](https://www.mpcaaca.org/_files/ugd/5a6d69_463fd96f910e4d5b8b9402683fa7f266.pdf?index=true) The tournament winner, assuming they are not already the reigning champion, receives an opportunity to wrestle for the IWGP Junior Heavyweight Championship shortly after the tournament ends.[3](https://www.thesmackdownhotel.com/tournaments/njpw-best-of-the-super-juniors) The link runs both ways: champions have vacated the title to enter the tournament, as Liger did on April 15, 1991 for the Top of the [Super Junior](https://www.edgepedia.org/super-junior) tournament, with Norio Honaga winning the ensuing round-robin final.[4](https://www.wrestling-titles.com/japan/newjapan/iwgp-j.html)
