Commercial raceways are pretty rare outside of the US, but here's one in Yokohama, Japan, with three interesting six-lane tracks. I don't have a lot of info, as the raceway's WEBSITE is only in Japanese, but I'd sure like to pay a visit to this facility if ever I end up across the Pacific.
The website does give English names for each of the tracks.
This track is named "Black Twister" and is noted as being for 1/24 scale cars.
This track is called "Laguna Seca" and is labled as being for both 1/24 and 1/32 cars.
This track is named "Rev-Limit", and is noted as being an "American-track." This is 1/24 and seems to be set up for two voltages, 12.0v and 13.8v.
The raceway might be in Japan, but the racers there certainly know their US and European racing history, as shown by this selection of cars from their website
