**Tsuchiya Engineering** is a Japanese motor racing team based in [Fujisawa, Kanagawa](/source/Fujisawa%2C_Kanagawa), which competes in the GT300 class of [Super GT](/source/Super_GT).

A long-time Toyota-fielding team in [Super GT](/source/Super_GT), the team won three drivers' and teams' titles in the GT300 class, as well as two [Japanese Touring Car Championship](/source/Japanese_Touring_Car_Championship) teams' titles in Division-3.

## History

### Origins and first stint in Super GT (1971–2008)

Haruo Tsuchiya (1945-2021), a former motocross rider, worked at TOMEI Automotive from 1968 to 1971 to create his own shop and team.[1] The team initially competed in local touring car races, before entering [JTC](/source/Japanese_Touring_Car_Championship), where it won the Division-3 title twice, in 1989 and [1990](/source/1990_Japanese_Touring_Car_Championship).[2] Tsuchiya entered [JGTC](/source/JGTC) in 1997 with a [Toyota MR2](/source/Toyota_MR2) and won its first title in [1998](/source/1998_All_Japan_Grand_Touring_Car_Championship), after winning five out of six races with [Shingo Tachi](/source/Shingo_Tachi) and [Keiichi Suzuki](/source/Keiichi_Suzuki_(racing_driver)) behind the wheel.[3] The following year, the team partnered with A'PEX and scored a lone win at [Fuji](/source/Fuji_Speedway) and two more podiums to secure the drivers' title with [Morio Nitta](/source/Morio_Nitta), as well as taking their second consecutive teams' title.[4]

Entering GT500 in 2000, the team fielded a [Toyota Supra](/source/Toyota_Supra) until 2006, before fielding a [Lexus SC430](/source/Lexus_SC) for the following two years.[5] In their nine-year stint in the category, the team scored five podiums, including their only win at [Okayama](/source/Okayama_International_Circuit) in 2005.[6] At the end of the 2008 season, the team suspended its motorsport activities in 2009 due to the economic recession and the reduction of manufacturer support.[7][2]

### Team Samurai and Return to Super GT (2010–present)

Haruo's son [Takeshi](/source/Takeshi_Tsuchiya), founded 25 Racing/Team Samurai in 2010, with his father as manager.[2][8] Across the next four years, the team competed in [Super GT](/source/Super_GT) until 2011, before then competing in [Porsche Carrera Cup Japan](/source/Porsche_Carrera_Cup_Japan), [Super Taikyu](/source/Super_Taikyu) and [JAF Formula 4](/source/Formula_Beat).[9] In 2015, Tsuchiya Engineering made their return to GT300 competition, with [Takeshi Tsuchiya](/source/Takeshi_Tsuchiya) and [Takamitsu Matsui](/source/Takamitsu_Matsui) driving a [Toyota 86 MC GT300](/source/Toyota_86).[10] In the team's first full season since 2011, the Tsuchiya-Matsui pairing won at [Sportsland SUGO](/source/Sportsland_SUGO) and qualified on pole at [Buriram](/source/Buriram_International_Circuit) to end the season ninth in points.[11] Retaining both Tsuchiya and Matsui for 2016, the pair scored wins at [Buriram](/source/Buriram_International_Circuit) and [Motegi](/source/Twin_Ring_Motegi) to secure their third drivers' and teams' titles.[12] Ten days after the season-finale, Haruo was diagnosed with oral cancer, and as a result Takeshi retired from full-time racing to take over the running of the team.[2]

For the team's title defence, Matsui remained for a third consecutive season as [Kenta Yamashita](/source/Kenta_Yamashita) replaced Tsuchiya as the team's second driver.[13] In their only season together, the Matsui-Yamashita pair won at [Autopolis](/source/Autopolis) and finished third at [Sportsland SUGO](/source/Sportsland_SUGO) to secure sixth in the teams' standings.[14] Matsui remained with the team as the sole full-time driver for the 2017 season, finishing third at [Okayama](/source/Okayama_International_Circuit) and second at [Suzuka](/source/Suzuka_Circuit) alongside [Sho Tsuboi](/source/Sho_Tsuboi) as the team ended the year eighth in points.[15][16] In 2019, Matsui remained with the team as he was joined by [Kimiya Sato](/source/Kimiya_Sato), as they scored a best result of fourth at [Buriram](/source/Buriram_International_Circuit) and qualified on pole three times to end the year 18th in points.[17]

Ahead of 2020, the team switched to a [Porsche 911](/source/Porsche_911_GT3#991_GT3_R_(2019–2023)),[18][19] fielding it until 2021, scoring a best result of fifth at [Motegi](/source/Twin_Ring_Motegi) in the latter year, before the team switched to a self-built [Toyota GR Supra](/source/Toyota_GR_Supra#Motorsport).[20][21] In their first year with the Supra, the team scored a single points finish at [Sportsland SUGO](/source/Sportsland_SUGO), by finishing tenth, to end the year 34th in the teams' standings in a season in which they missed the second [Fuji](/source/Fuji_Speedway) round following a testing crash at [Suzuka](/source/Suzuka_Circuit).[22]

In [2023](/source/2023_Super_GT_Series), at the fourth round of the season at [Fuji](/source/Fuji_Speedway), both Tsuchiya-ran cars caught fire, leading to both cars withdrawing from the following event and the rest of the season.[23] Tsuchiya then started a fundraiser known as the "Hopico Revival Project" in order to help the team return to racing.[24] The team returned to GT300 competition in the following year with [Takamitsu Matsui](/source/Takamitsu_Matsui) and [Togo Suganami](/source/Togo_Suganami), with a rebuilt version of "Hopico".[25]

### Partnership with Max Racing (2020–2023)

Before the [2020 Super GT season](/source/2020_Super_GT_Series) it was announced that Tsuchiya Engineering would support series newcomers Max Racing, by servicing their car.[26] The partnership lasted until the 2023 Fuji GT 450km Race, where both cars caught fire and Max Racing ceased operations with immediate effect.[27] In their three-year partnership, Max Racing scored a lone win at [Suzuka](/source/Suzuka_Circuit) in 2021 and scored a best points finish of fourth the same year.[28]
