This car is produced by a local furniture maker in Maniwa city - and like all small companies in Japan, they dont have a site that I can direct you to.
The "Wooden Supercar" is 1.3 meters wide x 2.5 meters in length x 1.1 meters high and has a max speed of 80km/h.
You can see last nights coverage of this car at WBS (video is only available for today and is darn Real Player). You can also see earlier coverage in the Otavids section.
