Thunder Dolphin (サンダードルフィン) is a steel roller coaster at the Tokyo Dome City Attractions amusement park, which is part of Tokyo Dome City in Tokyo, Japan. The ride was designed and constructed by Intamin. At 80 metres (262.5 ft) tall, Thunder Dolphin is one of the tallest continuous circuit roller coasters in the world, currently ranked number 10. Following an incident in which a 25 centimetres (9.8 in) long bolt fell from the ride while in motion on 5 December 2010, injuring a 9-year-old visitor, operation of the ride was suspended until 1 August 2013, when the ride reopened.
Thunder Dolphin's 1,066.8 metres (3,500 ft) long course passes through both a hole in the LaQua building, and through the Big-O, the world's first centerless Ferris wheel. Thunder Dolphin has a maximum speed of 130 kilometres per hour (81 mph).
