A total of 263 firms from Japan and 13 other countries will participate in the 37th Tokyo Motor Show this fall at the Nippon Convention Center, better known as Makuhari Messe, in Chiba Prefecture, organizer said Tuesday.

The 12-day show this year features cars and motorcycles. The annual event alternates between such vehicles and commercial vehicles.

A media preview will be held Oct. 24 and the event will open to the public Oct. 25, the Japan Automobile Manufacturers Association said.

The number of participants is expected to be at the same level as the 35th motor show in 2001, the last time cars and motorcycles were displayed. The total is down 10 from the 2002 show, however.

The theme of this year's show is "The Challenge: Driving Toward a Better Future."

A wide variety of symposiums and special events, including test rides of environmentally friendly and safety-conscious cars, will be held, it said.

It will be the first show to be organized by the association since its merger with the Japan Motor Industrial Federation, which used to organize the event.
