Top Roller Coaster's Of The World
Dodonpa messes with your mind from the moment it starts, as passengers are forced to wait anxiously in a darkened tunnel before the countdown to an insanely fast acceleration out of the tunnel, screaming down the track and then getting fired up and over two humps which have 90 degree drops on each side. When the Dodonpa was opened in 2001, it was the fastest roller coaster in the world. As of 2010, it is not the fastest but still has the highest launch acceleration at 2.7 g. It is 52 meters (170 feet) tall, and has a launch speed of 172 km/h (107 mph), which is reached in less than 2 seconds. Located at Fuji-Q Highland, Fujiyoshida, Yamanashi, Japan, its hill goes straight up, down a hairpin curve, and then goes straight down.
