Although its height and speed records have been broken since its debut, it remains the longest coaster in the world.
With a maximum speed of nearly 153 km/h (95 mph), it is among the fastest coasters featuring a traditional lift hill.
From the brake run, trains pass through the transfer track and storage area before making a sweeping left turn to return to the station.
The extra steel was a large part of the reason the coaster cost over JP¥7 billion to build.
A passenger suffered a serious back injury and a 28-year-old man swimming in the water park pool was injured when he was hit in the hip with the 32 centimetres (13 in) wheel.
