Gearheads and imperial family enthusiasts got a close-up look Thursday at a specially built car that carried Emperor Naruhito and Empress Masako in a parade earlier this month to commemorate the emperor's enthronement.

The customized convertible version of Toyota Motor Corp.'s Century luxury sedan, painted in glossy black and equipped with a white leather interior, will be exhibited at the State Guesthouse in Tokyo until Jan. 5.

The government selected the car from a pool of options put forward by five automakers due to its safety features and minimal environmental impact. The height and angle of the car's seats are adjustable to allow roadside well-wishers the best possible view of the imperial couple.
