Located just off of the highway that runs between Tokyo and Yokohama is a rest stop known as the Daikoku Parking Area. The parking area rests on a man made island in Tokyo Bay. The island is encircled in a massive concrete coil of twisting highways. During the day the stop is just like any other, a place for truckers and other people commuting to and from the busy Yokohama shipping port to rest and refuel. The mood of the area changes dramatically at night, turning into what could be described as a car fanatics mecca. Groups dedicated to every niche and facet of auto tuning meet and share their projects.
