An amusement park centered on the Cosmo Clock 21 — one of the world's largest clock-ferris wheels at 112.5 metres. Located at the heart of Minato Mirai, it's iconic on the Yokohama skyline and especially magical at night.
Yokohama Cosmo World is a waterfront amusement park in the Minato Mirai district of Yokohama, Kanagawa Prefecture, distinguished by its centrepiece: the Cosmo Clock 21, a 112.5-metre diameter ferris wheel that was the world's largest when it opened in 1989. The wheel functions simultaneously as a working clock, with LED displays across its face showing the current time — a night-time spectacle visible from across Yokohama Bay. The park occupies land between the Minato Mirai canal and the harbour, split across two zones connected by footpaths.
The park's rides cover a range of thrill levels. The Diving Coaster Vanish, a steel roller coaster, dips into an underground tunnel beneath a reflecting pool at its most dramatic moment. A log flume, drop tower, and various family-oriented attractions fill out the park's offerings. Unlike many amusement parks in Japan, Cosmo World has no general admission charge — visitors pay only for the specific rides they choose. The Cosmo Clock 21 ferris wheel costs ¥900 per person for a full rotation taking approximately 15 minutes, during which the gondola rises above the surrounding buildings for unobstructed harbour views.
The park's night-time atmosphere is its strongest asset. After dark, the Cosmo Clock 21's LED display cycles through colour patterns and the harbour water reflects the combined glow of the wheel, Landmark Tower, and waterfront restaurants. The promenade surrounding the park fills with evening visitors regardless of whether they are riding anything — the free-entry structure means the park functions as much as a gathering point as a traditional amusement venue.
Weekend evenings see the heaviest crowds. Weekday evenings and early afternoons (when lighter family rides open from 11:00) provide a more relaxed experience. The park is a 5-minute walk from Minato Mirai Station.
