MAKUHARI, Chiba Pref. -- The 38th Tokyo Motor Show opened to the media Tuesday at the Makuhari Messe convention center here, showcasing low-emission commercial vehicles and so-called welfare vehicles.

The show, organized by the Japan Automobile Manufacturers Association, is the third and last of its kind solely dedicated to commercial vehicles. In 1999, the show was divided into two categories, one featuring cars and motorcycles and the other featuring commercial vehicles.

Although the show has featured the two categories alternately, they will be merged at the 40th Tokyo Motor Show in 2007, which will be held biennially thereafter.
