Overview
JLOC, originally the Japan Lamborghini Owners’ Club, is a Japanese organization established by Lamborghini owners and later developed into one of the marque’s best-known independent motorsport operations in Japan. It began in 1980 when owners of Lamborghini Miura cars sought a practical solution to difficulties obtaining spare parts and maintaining their vehicles. The original Kansai-based organization was dissolved after several years, but it was re-established in 1987 following a request from Lamborghini. Isao Noritake, a member of the first organization, became chairman of the revived club. The group held its first meeting in 1988 at Sanza Villa near Lake Hamana with 17 members; membership had grown to more than 100 by 2000. The club’s motorsport identity emerged in the early 1990s. Member Teruaki Terai wanted to enter the newly created All Japan Grand Touring Car Championship, despite lacking both a competition car and a sponsor. In 1993 he acquired a fire-damaged Lamborghini Countach 25th Anniversary and began converting it for racing with Masahiko Mearashi. The project was incomplete when the 1994 season began, but organizers encouraged JLOC to enter the opening event. Running as KEN WOLF with Terai Engineering, the team adapted a road-going Countach with changes to its bodywork, suspension and engine. Although the car was unreliable, it scored points with an eighth-place finish at Sendai. JLOC subsequently worked with Lamborghini-linked engineers and constructors to develop racing versions of the Diablo. The Diablo Jota competed in the 1995 and 1996 JGTC seasons, while the Diablo GT-1, acquired after a financially troubled development program, became the team’s principal car from 1997 through 2000. JLOC later redeveloped it into the Diablo JGT-1 and raced that model from 2001 to 2003. These GT500-era Lamborghini projects were technically distinctive but generally struggled against factory-backed opposition. The team moved to the Lamborghini Murciélago R-GT for 2004 and, after JGTC became Super GT, eventually shifted to the GT300 category. The full transition took place in 2006, when JLOC expanded to two cars and immediately won the GT300 season opener at Suzuka with a Murciélago RG-1. During the following decade JLOC campaigned several generations of Lamborghini race cars, including its own Gallardo RG-3, FIA GT3-specification Gallardo, Gallardo GT3 and Huracán GT3. The team expanded and contracted its entry size according to equipment and program requirements, at times operating as a four-car organization. Its results included a GT300 victory at Sportsland Sugo in 2014 and progressively stronger championship campaigns with the Huracán. The number 88 car became closely associated with JLOC, reflecting the club’s first 1988 meeting. JLOC has also competed outside Super GT. It attempted to enter the 24 Hours of Le Mans in 2005 and made its race debut in 2006 with a Murciélago RG-1LM. It returned in 2007 with logistical support from DAMS, although a qualifying accident and subsequent mechanical failure ended the effort. The team entered again in 2009 and has also appeared in Asian endurance racing. These programs extended JLOC’s role from an owners’ club into an independent engineering, preparation and race-entry operation. In the late 2010s and early 2020s, JLOC retained a strong Lamborghini focus in Super GT. Takashi Kogure and Yuya Motojima became the principal drivers of the number 88 car, while a second entry was fielded by rotating combinations including Kosuke Matsuura, Natsu Sakaguchi, Tsubasa Takahashi and Shinnosuke Yamada. The COVID-19 pandemic disrupted planned international driver arrangements in 2020. JLOC’s 2023 season included an upgrade of the number 88 car to Huracán GT3 Evo 2 specification after an earlier car was written off in a crash; the second car received the newer specification later than planned. In 2024, Kogure and Motojima delivered JLOC its first Super GT GT300 championship, winning four races. JLOC is therefore best understood not as a conventional consumer product brand, but as a Japanese enthusiast organization and Lamborghini-centered racing team with a long-standing presence in national and international motorsport.
History
JLOC’s history has two connected strands: a Japanese Lamborghini owners’ club and a racing team built from that community. The club was first organized in 1980 by Miura owners who faced limited access to replacement parts and specialist maintenance. After the original Kansai organization ended, Lamborghini requested its revival in 1987. Isao Noritake became chairman, and the re-formed group held its first meeting in 1988 with 17 members. The club’s later use of racing number 88 commemorates that meeting. Membership expanded to more than 100 people by 2000. The racing program developed from Teruaki Terai’s ambition to enter JGTC. A damaged Countach acquired in 1993 was intended to become JLOC’s first race car, but preparation took longer than expected. Organizers nevertheless invited the project to the 1994 season opener. The largely road-derived car achieved only limited reliability but scored points at Sendai. For 1995, JLOC asked Lamborghini to support development of a Diablo homologation special. Three Diablo Jotas were produced, although the competition cars did not score championship points in 1995 or 1996. Terai died of cancer in 1995, but the team continued. JLOC purchased a Diablo GT-1 racing car in 1997 after the wider GT1 project was curtailed by financial difficulties. The car raced in JGTC for four seasons and scored points in 1998. It was then substantially redeveloped as the Diablo JGT-1 for 2001. JLOC adopted the Murciélago R-GT in 2004, but spare-parts limitations occasionally forced the older Diablo back into service. The team’s lack of competitiveness against factory-supported GT500 entrants helped drive the move to GT300 after JGTC’s transition to Super GT. The GT300 era brought more competitive results. JLOC won at Suzuka in 2006 with a Murciélago RG-1 and later developed and operated Gallardo RG-3 cars. FIA GT3 Gallardos were introduced in 2012, followed by the Gallardo GT3 and then the Huracán GT3 in 2016. The team achieved further podiums and wins while continuing to use number 88 as its principal identity. A Huracán GT3 Evo 2 upgrade was introduced to the number 88 car during 2023, while the second car received the specification after delays. JLOC’s endurance history includes Le Mans attempts in 2005, 2006, 2007 and 2009, plus participation in Asian endurance competition. Its 2006 Le Mans car completed 283 laps but was not classified after stopping before the finish. In 2007, a major qualifying crash destroyed the prepared car; a replacement R-GT was permitted, but the entry retired after one lap with a driveshaft problem. The team’s strongest modern result came in 2024, when Kogure and Motojima won the GT300 championship with four victories. This result marked the culmination of a three-decade progression from an owners’ club using a modified road car to an established Lamborghini specialist capable of developing, preparing and campaigning GT machinery at championship-winning level.

JGTC race car · 1994
Lamborghini Countach race car
JLOC’s first competition car was based on a fire-damaged Lamborghini Countach 25th Anniversary acquired by Teruaki Terai. Because the build was completed under severe time pressure, the car remained close to road specification while receiving revised bodywork, suspension and engine components. It entered the 1994 JGTC season and finished eighth at Sendai, its principal championship result.
JGTC race car and homologation special · 1995
Lamborghini Diablo Jota
The Diablo Jota was developed at JLOC’s request for JGTC competition. Three examples were built: two intended for racing and one for road homologation. JLOC campaigned the cars in 1995 and 1996, but they did not score championship points in those seasons.
GT racing car · 1997
Lamborghini Diablo GT-1 / JGT-1
JLOC acquired a Diablo GT-1 after the Lamborghini-associated GT1 project was halted and raced it from 1997 through 2000. The team later rebuilt the concept as the Diablo JGT-1 with a revised chassis, suspension and competition-specific components, using it from 2001 to 2003.
