In order to develop motor vehicles with high running performance, it is imperative to conduct vehicle running tests on road-holding ability, acceleration, vibration resistance, braking, aerodynamic performances. JARI has a wide variety of special-purpose vehicle test courses and a world-class high-speed oval track measuring an impressive 5,500 meters long per lap.

Most of JARI's test courses, including the high-speed oval track, were moved from their former locations in Tsukuba City to its Shirosato Test Center (STC) which was built as the comprehensive proving ground complex of JARI in 2005.
