Hakugei (白鯨, ‘White Whale’) is a steel hybrid roller coaster at Nagashima Spa Land in Kuwana, Mie, Japan — the country’s only Rocky Mountain Construction hybrid and the first RMC installation anywhere in Asia. Since opening on March 28, 2019, it has become one of the park’s signature rides alongside the record-setting Steel Dragon 2000.
Built as a top-to-bottom conversion of the wooden White Cyclone, Hakugei swapped every inch of track for RMC’s I-Box steel rail while reusing much of the original wooden support structure — a project that raised the ride’s height, speed, and G-forces far beyond what the wood-only coaster could deliver.
Quick Answer
Hakugei stands 55 m (180 ft) tall, hits a top speed of 107 km/h (66.5 mph), and covers 1,530 m (5,020 ft) of steel I-Box track with three inversions. It’s Japan’s only hybrid (wood-to-steel) roller coaster and rides at Nagashima Spa Land in Kuwana, Mie.
Hakugei Height, Speed & Key Stats
Hakugei’s 55 m (180 ft) height and 107 km/h (66.5 mph) top speed make it one of Japan’s tallest and fastest coasters, and by most rankings it’s the tallest, fastest, and longest hybrid coaster built anywhere in Asia. Within Japan overall — a country with an unusually deep bench of extreme coasters — Hakugei sits among the top handful for height and speed, just behind giants like Steel Dragon 2000 (also at Nagashima Spa Land) and Fujiyama.
The layout starts with an 80-degree, near-vertical first drop and builds up to roughly 4 G through a run of overbanked turns, two zero-gravity rolls, and a zero-gravity stall — RMC’s signature inversion where the train hangs weightless before rolling back over. Riders must be at least about 130 cm (around 4 ft 3 in) tall to board, a figure worth confirming with the park before your visit since height policies can be updated.

The Ride Experience
After the 80-degree first drop, Hakugei snaps through a dense sequence of airtime hills, overbanked turns, and three full inversions, including the zero-gravity stall that has become an RMC hallmark worldwide. The I-Box steel track delivers a noticeably smoother ride than a traditional wooden coaster despite the intensity, and the layout still traces the sprawling footprint of the original White Cyclone across the Nagashima peninsula.
Three trains, each seating 24 riders two-across with individual hydraulic lap bars and seatbelts, keep the line moving at a park-leading pace for such an intense ride. At 1,530 m of track and about two-and-a-half minutes per lap, Hakugei is unusually long for a coaster of its type, giving riders sustained ejector airtime between each inversion rather than one short, sharp burst.
From White Cyclone to White Whale
White Cyclone opened in 1994 as one of the largest wooden coasters in Asia, built by Intamin. After more than two decades of operation it closed in January 2018, and Rocky Mountain Construction began the I-Box conversion, recycling much of the existing wooden support structure while replacing every inch of the ride’s track with steel.
The rename to Hakugei honored both the coaster’s pale steel aesthetic and Nagashima’s coastal setting on the shores of Ise Bay. S&S Worldwide handled the lift-hill and brake systems, while Sansei Technologies served as the local construction partner — a collaboration that set the template for RMC’s later projects in Japan.
Nagashima Spa Land: Planning Your Visit
Nagashima Spa Land is a large amusement park within the Nagashima Resort complex in Kuwana, Mie Prefecture, best known for its lineup of record-chasing steel coasters — Steel Dragon 2000, Arashi, and Hakugei among them — alongside water park and hot spring facilities on site. It’s roughly an hour from Nagoya by car or shuttle bus, making it a popular day trip for coaster enthusiasts visiting the Chubu region.
The park sells both all-day passport tickets (admission plus unlimited rides) and cheaper entrance-only tickets, with discounted passports typically available after mid-afternoon; passes can also be pre-purchased at convenience stores like Family Mart and 7-Eleven in Japan. Operating hours shift seasonally and the park has occasional maintenance closures in the January–June window, so check the current schedule before you go. For up-to-date hours, ticket prices, and closure notices, see the official Nagashima Spa Land website.
How Hakugei Compares
Because it’s the only RMC hybrid in Japan, Hakugei doesn’t have a direct domestic rival — its closest comparisons are other RMC I-Box coasters abroad, like Steel Vengeance in the U.S., which share the same overbanked, airtime-heavy design language. Within Nagashima Spa Land itself, Hakugei trades the record-setting raw height and speed of neighboring Steel Dragon 2000 for a rougher-edged, more inversion-packed ride experience typical of RMC’s hybrid conversions.
