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.

"Eejanaika" is pronounced "Ee ja nai ka" and written in Japanese as "ええじゃないか", but the roller coaster's official spelling turns the second "え" upside down. Eejanaika has several meanings, but means "Hey, what the hell!" in this context and jokingly refers to whether a roller-coaster that turns and twists so much is safe to ride. This question is asked in an overhead announcement before each ride to which the attendees respond in unison "ええじゃないか".

According to the Guinness Book of World Records, "Eejanaika" is the roller coaster with the most inversions in the world. Throughout the ride, the riders go through 14 inversions. However, most of these inversions are accomplished by spinning the seats rather than actually inverting the track.

The track itself only inverts three times -
*Inside raven turn (½)
*full-full/zero-g roll (1)
*half camelback twist (½)
*outside raven turn (½)
*half camelback twist (½)This has led to some controversy in the roller coaster enthusiast community concerning the legitimacy of "Eejanaika's" claim. The Roller Coaster DataBase does not acknowledge these seat inversions for the purpose of record-holding. [http://rcdb.com/id3254.htm]
