The ride's top hat was removed and replaced with a vertical loop, announced in a February 2017 press release from the manufacturer. Steel fabrication was provided by Intermountain Lift, Inc. Dodonpa reopened on 15 July 2017 as Do-Dodonpa. The renovated and revamped ride featured an increased acceleration and maximum speed, which changed from in 1.8 seconds to in 1.6 seconds. The track length also increased from . The renovation made Do-Dodonpa the world's first air-powered coaster to feature an inversion, as well as the fastest coaster in the world with an inversion. On 13 March 2024, Fuji-Q Highland announced Do-Dodonpa's permanent closure.


Ride experience

prior to 2017). The train then entered a slight left turn before hitting a brake run. A second left turn followed by a right U-turn, both taken at slower speeds, brought the train back to the station. The ride had a total of 4 trains with 4 cars per train. Each car sat 2 riders side-by-side, resulting in a total capacity of 8 riders per train.


Characteristics

The 55 second ride took the rider across of steel tracks, and peaked at a maximum height of . This gave the ride an

While the ride has operated at speeds of up to , its rubber tires prevented it from performing reliably at these speeds, so engineers capped the speed at prior to the ride's renovation. Before Do-Dodonpa's initial opening, only two roller coasters reached or went beyond the barrier.

Incidents

Since its opening in 2001, Do-Dodonpa has had several incidents resulting in injury to passengers. On 15 May 2007, a 37-year-old man sustained a minor injury when a plastic cover at the front of the train came loose and hit his right knee. The man was not badly injured because the plastic cover disconnected near the end of the ride when the train had slowed down significantly. Fuji-Q Highland stated that the cover likely came off due to cracks created over time by vibrations in the train. Further inspection of the other trains showed no similar damage. From December 2020 to August 2021, there were 18 injuries sustained while riding Do-Dodonpa, which included nine incidents of broken bones. Fuji-Q Highland owner Hiroaki Iwata apologized for the injuries at a press conference speech on 31 August 2021, stating that an official investigation of these incidents had been ongoing since December 2020. On 13 March 2024, the park officially announced the permanent closure of the ride.
