As automakers struggle with a shrinking domestic market, participants in the 40th Tokyo Motor Show this fall hope to remind people just how much fun it is to get behind the wheel.

"One of the attractions of this year's show is that visitors can see the latest technologies of automobiles, commercial vehicles, motorcycles and auto parts all in one place," Japan Automobile Manufacturers Association President Fujio Cho said Thursday.

This year's show places greater emphasis on visitor participation, such as test-driving vehicles equipped with the latest environment-friendly and safety features.
