Eejanaika (ええじゃないか) is a 4th Dimension roller coaster at Fuji-Q Highland in Fujiyoshida, Yamanashi, Japan. The ride is the world's second 4th Dimension coaster, the first being X (now X²) at Six Flags Magic Mountain in California.

Description[]

Eejanaika was designed by S&S Worldwide and opened at the park on July 19, 2006. The ride has a design in which the seats can rotate forward or backward 360° in a controlled spin. This is achieved by having four rails on the track: two of these are running rails while the other two are for spin control. The two rails that control the spin of the seats move up and down relative to the track and spin the seats using a rack and pinion gear mechanism. Eejanaika translates to "Ain't it great!" in Japanese.

Incidents[]

On 4 August 2006, brake noise caused an emergency stop, shutting the coaster down until 9 August.
On 13 December 2007, a stopped vehicle suddenly started moving, and an employee who was inspecting the coaster was caught between the vehicle and the rail, breaking his chest bone and sustaining a serious injury.
On 3 January 2009, slacking of the lift hill's chain caused an emergency stop, which ceased the coaster's operations for the day. Operations resumed the day after.
On 29 April 2012, a bolt broke and fell from a running vehicle, hitting the forehead of a female park guest who was walking under the tracks, causing minor injuries. The ride was closed for two months until 11 July, when Fuji-Q reopened Eejanaika with new safety procedures, including the closure of the walkway where the incident took place, as well as the ban of wearing shoes while riding, and a ban on bringing audio/video equipment onto the ride.^[1]
On 28 February 2025, a maintenance worker was killed after being hit by one of Eejanaika's trains while inspecting the ride.^[2] The ride was closed for a period of time following this incident.
