8 Thunder Dolphin
Tokyo Dome City, Tokyo, Japan
Comparatively tame by the speed, height and acceleration standards set by other rollercoasters on this list, Thunder Dolphin has a unique trick up its sleeve that renders it worthy of a place on the scariest rollercoasters list. Thunder Dolphin’s track passes through the world’s first centre-less big wheel and through a building too. Not only that, but Thunder Dolphin is also the world’s sixth tallest continuous track rollercoaster. Respect.
