Eejanaika, Steel hypercoaster at Fuji-Q Highland, Japan
Eejanaika is a steel hypercoaster at Fuji-Q Highland that uses a four-rail system with two running rails and two control rails to guide the ride. The seats rotate independently during the journey, completing multiple full rotations as the train travels along the track.
The ride opened on July 19, 2006, becoming the second fourth-dimension coaster built anywhere in the world after X2 at Six Flags Magic Mountain in California. Between 2013 and 2014, the structure received a new color scheme in dark brown and grey to blend better with the landscape surrounding Mount Fuji, which had recently been named a UNESCO World Heritage Site.
The name comes from a folk expression used in Japan during the Edo period when people shouted in joy after hearing unexpected good news. In Japanese script, the second kana character is written upside down, reflecting the playful nature of the phrase and still visible today in the ride's signage.
The coaster can carry up to 1000 riders per hour and reaches speeds around 78 mph (126 km/h) along its roughly 3780-foot (1152-meter) course. Visitors should expect wait times, especially on weekends, as this remains one of the most popular attractions in the park.
The supports and rails were repainted after Mount Fuji received World Heritage status to help the structure fit into the surrounding landscape. The choice of dark brown with grey elements was intended to prevent the coaster from standing out as a contrast against the natural silhouette of the mountain when seen from a distance.
