Career

Formula Three After competing in Formula Dream in 2004 and 2005, winning the championship in his second year, Tsukakoshi moved into the All-Japan Formula Three Championship for the final three rounds of the 2005 season, finishing fourteenth in the standings competing for M-TEC. He remained with the team for the 2006 season, finishing fifth in the standings, taking a victory at Suzuka. Another fifth place championship finish followed in 2007, as Tsukakoshi took two wins for Honda Team Real at Okayama and Suzuka. He also finished in second place at the prestigious Macau Grand Prix for Manor Motorsport, finishing behind Oliver Jarvis. Tsukakoshi moved to Manor Motorsport and the Formula Three Euroseries for the 2008 season. He finished seventh in the championship standings, with a best result of second place on four occasions.

Super Formula

After a season in Europe, Tsukakoshi made his debut in Formula Nippon in 2009 with HFDP Racing, which was run by Real Racing. He raced with them before moving to Dandelion Racing in 2011. In 2012, he came close to winning the title, losing out to Kazuki Nakajima by three points. In 2013, he returned to Real Racing, and he raced with them for six seasons. Tsukakoshi initially was not scheduled to compete in the 2019 season, but he replaced Tristan Charpentier from the second round of the season onwards. Real Racing announced it had withdrawn from the 2020 season, thus leaving Tsukakoshi without a seat. That season, he was hired by Drago Corse to replace Tatiana Calderon, who was unable to race due to COVID-19 travel restrictions, for the Okayama and Sugo rounds that year. He made a further three starts for the team in 2021, again replacing Calderon, which were his final outings as a driver.

Tsukakoshi was later recruited by the series to develop the new Dallara SF23 chassis as the test driver of Honda's development car. He also became part of a new ThreeBond Racing (formerly Drago Corse) structure as an advisor , and later took on the role of team director.

Super GT Tsukakoshi made his debut with Honda GT500 team Real Racing in the 2008 Suzuka 1000km. He has driven for the team full-time since 2009, and finished runner-up in the 2013 standings alongside Toshihiro Kaneishi.
