JLOC was first founded in 1980 by a group of Lamborghini Miura owners due to difficulties with getting spare parts and maintenance of their cars.

[1][2] In the early 1990s, JLOC member Teruaki Terai wanted to take part in motorsport despite lacking a race car or a sponsor.

Circuit no Ōkami’s mangaka Satoshi Ikezawa was invited by Mearashi to negotiate a deal with exotic car dealership Art Sports to supply a road-going Countach for JLOC.

Due to the limited amount of time, the Countach was kept mostly stock but it received modifications to its bodywork, suspension, and engine.

The 2000 version of JLOC’s Diablo GT-1 famously became the first Lamborghini car to be featured in Gran Turismo due to a licensing quirk.

The Diablo JGT-1 was raced for three seasons but despite this, the car continued to score little success as it struggled to compete with the factory-backed entries in GT500.

[4] JLOC made the full switch to GT300 class in the 2006 season and expanded to a two-car team with the addition of the #87 Murciélago RG-1, driven by Koji Yamanishi and Hisashi Wada.

JLOC expanded further into a four-car team in 2007, entering two self-developed Lamborghini Gallardo RG-3s alongside the two Murciélago RG-1 entries.

JLOC downscaled further into a two-car team in 2014 and scored one win at Sugo, courtesy of Orido and Takayuki Aoki in the #88 Gallardo GT3.

Since Hiramine was signed by Kondo Racing in the off-season, Yuya Motojima was transferred from the #87 team to join Kogure in the #88 car.

Couto and Lamborghini factory driver Dennis Lind were due to compete with the team in 2020, but the advent of the COVID-19 pandemic meant that they were unable to foresee their deal with JLOC that year.

The team also played a crucial role in the championship as two late overtakes from both JLOC cars at Motegi, including a last-lap overtake on GAINER's Ryuichiro Tomita by Kogure, allowed Kondo Racing to clinch the GT300 title after the right front wheel of Kondo's Nissan GT-R GT3 came off the car midway through the race.

JLOC planned to also introduce a second Huracán GT3 Evo 2 for the #87 team later in the season, but it was scrapped due to Balance of Performance concerns.

[21] The upgraded machinery allowed Kogure and Motojima to tie JLOC's best championship finish of seventh, having scored victory in the last round at Motegi.

JLOC’s Super GT drivers Marco Apicella, Yasutaka Hinoi, and Koji Yamanishi would share the driving duties for the team’s debut at Le Mans.

As Apicella and a number of mechanics had flown back home after the team’s initial failure to qualify, JLOC elected to start and park the car after completing just one lap.

Yogo, Yamanishi, and Hiroyuki Iiri are elected to drive JLOC’s newly-prepared Murciélago LP670 R-SV for the race.

The team retired at the 18th hour mark after only completing 138 laps due to suffering from numerous puncture and transmission problems.
