Moonsault Scramble (ムーンサルト・スクランブル) was a shuttle roller coaster located at Fuji-Q Highland in Fujiyoshida, Yamanashi, Japan.

According to the Guinness Book of Records, Moonsault Scramble was the tallest roller coaster in the world at 70 metres (230 ft) when it opened.

[citation needed] Moonsault Scramble was known for producing extremely high g-forces on its riders.

[5] According to the Sun Sentinel in 1989, the Guinness Book of World Records recognized the height as 75 metres (246 ft), but the American Coaster Enthusiasts organization refused to recognize the claim, describing it as "disappointing" since riders do not approach the maximum height or "go over the top".

[6] The Roller Coaster DataBase (RCDB) lists the overall height as 70 metres (230 ft).
