Eejanaika is a steel 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 Valencia, California, United States. Eejanaika is the taller, faster, and longer of the two.
Eejanaika, designed by S&S Arrow, is a "4th Dimension" coaster, a design in which the seats can rotate forward or backward 360 degrees 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.
