Currently, the park has four major roller coasters. Fujiyama, the park's centerpiece attraction, was the world's tallest and fastest roller coaster when it opened in 1996, and it continues to rank among the best coasters in the world. Dodonpa (2001) is currently the parks speediest coaster and the world record holder for fastest acceleration. Eejanaika (2006), a "4th dimension" roller coaster with seats rotating within the car, has the most inversions of any roller coaster. Finally, Takabisha, built in 2011, is the steepest roller coaster in the world.
