Fuji-Q Highland amusement park is a popular destination for tourists and thrill-seekers alike.
Located at the foot of Mount Fuji, visitors are afforded a scenic backdrop as they play games and ride the park's large variety of attractions.
Recently however, one of the park's popular roller coasters, the Do-Dodonpa, was shut down after several riders suffered serious injuries.
Injuries occurred between Dec. 2020 and Aug. 2021
According to Washington Post, four passengers suffered back and neck fractures after riding the roller coaster between Dec. 2020 and Aug. 2021, but were only reported to officials recently.
The four incidents occurred among men and women in the 30 to 50 age range.
Their injuries included a cervical fracture and a thoracic spine fracture, with the latter potentially requiring three months of hospitalisation.
The roller coaster has since been closed "due to a safety overhaul".
BBC reported that the company that constructed the roller coaster, Sansei Technologies, has also issued an apology to the injured passengers.
However, the company clarified that the connection between the injuries and the ride "is not confirmed", and added that they would wait for the regional government to conclude its investigations.
World's fastest-accelerating roller coaster
The Do-Dodonpa opened in 2001 and is the world's fastest-accelerating roller coaster.
After a renovation in 2017, the roller coaster can now reach 180km/h in a mere 1½ seconds.
Additionally, it has the world's largest loop with a diameter of 39.7m., with the top of the loop being 49m above ground.
The Fuji-Q Highland website describes the Do-Dodonpa as having a "super death" speed.
