The Tsukuba Circuit is a motorsport race track in Shimotsuma , a neighboring city of Tsukuba in Japan .
There are two courses: a so-called 2000 course and a 1000 course, both of which are named for their approximate length. The 2000 course is 2.045 km long and 10 to 17 meters wide, the longest straight has a length of 437 m. In motorcycle races , an additional chicane is driven through, increasing the length of the route to 2.070 km. The 1000 course is 1,039 km long and 11 to 17 meters wide.
Construction work on the 2000 course began in 1966, but the track was not opened until 1970. In 1990 the chicane for the motorcycle variant was installed, and in 2001 the 1000 course was built and opened.
The circuit is a regular venue for runs of the All Japan Road Race Championship , which is one of the most important national motorcycle championships in the world, as well as runs of the D1 Grand Prix of a popular drift racing series. From 1987 to 1994 races of the Japanese Touring Car Championship were held here, and until 2001 races of the Japanese Formula 3 Championship were held.
The race track is popular for hosting so-called time attack competitions. In these, the competitors do not drive against each other, but against the clock. National club and drift events as well as motorcycle races also take place here.
Time attack
Timeattack is a motorsport that is all about achieving the fastest lap. The sport originated in Japan and is organized on circuits like Tsukuba. The events allowed tuning companies to test the effectiveness of their modified vehicles on the racetrack. However, the decisive factor for such races was that street-legal tires were used; H. maximum semi-slicks, no slicks. This later resulted in a sport and vehicles were specially converted for time attack events. These include a. the HKS CT230R Lancer Evolution , or the HKS TRB-03 ( Tsukuba Record Breaker , TRB) GT86 . Especially with the latter, the entire vehicle (chassis, engine, drive, aerodynamics) was developed explicitly for time-attack runs on the Tsukuba Circuit. The official record was set in December 2017 by Tomohiko "Under" Suzuki in the Scorch Racing Team's Nissan Silvia S15 with 50.366 seconds on semi-slicks. The HKS TRB-03 drove a time of 49.445 seconds at the beginning of 2018, but on slicks, which is why the time cannot be compared with other time attack times.
