The Tokyo Motor Show is a biennial auto show held in October-November at the Makuhari Messe, Chiba City, Japan for cars, motorcycles and commercial vehicles. Hosted by the Japan Automobile Manufacturers Association (JAMA), it is a recognized international show by the Organisation Internationale des Constructeurs d'Automobiles, and normally sees more concept cars than actual production car introductions which is the reason why the auto press see the show as one of the motorshow's big five (along with Detroit, Geneva, Frankfurt and Paris).
The show, then called All Japan Motor Show was first held in an outdoor venue called Hibiya Park, the show was considered a success with 547,000 visitors over ten days and 254 exhibitors displaying 267 vehicles, but of the amount of vehicles only 17 of them were passenger cars as the show was dominated by commercial vehicles. In 1958, due to construction of a subway and underground parking lot near Hibiya Park, the show was shifted to the Korakuen Bicycle Racing Track. The show, as the previous year was marred by heavy rain, in 1959 the event moved indoor to its newly opened Harumi Showplace venue which was three times the size of its previous venue.
Onward from 1973, as the organisers decided not to host a show for the following year due to the international energy crisis, the show became a biennial event after the organisers decided that the event should be held every two years. The show relocated to its current venue, the Makuhari Messe in 1989 and due to high public demand for vehicles in everyday use and the fact concept cars dominate the show, the show returned to being an annual event from 2001 to 2005 with a show for passenger cars and motorcycle and another for commercial vehicles for the following year. However from 2007 onwards the event will (once again) return to a biennial schedule which combines both passenger and commercial vehicles, including motorcycles and auto parts.
