Tsukuba Circuit (Japanese: 筑波サーキット, Tsukuba Sа̄kitto) is a motorsport race track located in Shimotsuma, a neighboring city of Tsukuba, Ibaraki Prefecture, Japan. It is 2.045 kilometres (1.271 mi) long, with 32 pit garages and a 437 m (0.272 mi) long back straight.[1] There is a small chicane used only for motorcycle racing that increases the track's total length to 2.070 kilometres (1.286 mi).

The track was established in 1966 with the aim of attracting young people to participate in motor sports, but was not actually completed until 1970.[2] At the present time, an event is held every week.[3] The track has a large variety of corners, ranging from wide sweepers to hairpins.[2] The circuit accommodates 8500 spectators on the track, 3000 in the stands, 5000 on lawn seats, and 500 standing over the pits.[2]

Admission is free on weekdays and ¥500 on weekends, but only when there are no scheduled events. Visitors are allowed to drive on the track with a license. Tsukuba Circuit is not accessible by public transportation, so renting a car is the best way to get there. A taxi is also available from Kanto Railway's Soudou Station, though it will take longer.

Time Attack[edit]

Tsukuba's "Time Attack" event (alternatively known as Super Lap or Tuner Battles) originated in Japan when the tuning media organized the event on race circuits such as Tsukuba, as a proving ground for street tuned cars built at a large budget by highly respected tuning companies. As a result of the quick rise in popularity, tuners developed specialized cars to beat the competition,[4] including the purpose-built HKS CT230R Lancer Evolution with a body made entirely out of carbon fibre.

Unlike other timed motorsport disciplines such as sprinting and hillclimbing, the car is required to start off under full rolling start conditions following a warm-up lap, where they will have to accelerate out as fast as possible to determine how fast they enter their timed lap.[4] Commonly, as competing cars consist of modified road-going models, they are required to wear tires authorized for road use. In all, drivers are allocated to three laps in a final event run; warm-up, timed and cool-down.[4]
