498 Tokio is a minor planet orbiting the Sun.
Tokio was discovered by Shin Hirayama in Tokyo on March 6, 1900. However, he was not able to determine its orbit. After it was rediscovered by Auguste Charlois on December 2, 1902, Charlois gave Hirayama the honor of naming it. Hirayama chose to name it Tokio after the city by the same name (Tokio is an older romanization).
The size of Tokio is 85 km x 60 km (determined by occultation in Japan on February 18, 2004).
