Cosmo Clock 21 is a Ferris wheel in Yokohama Cosmo World that looks down over Yokohama Port and Minato Mirai. One rotation takes 15 to 30 minutes, and in the evening the port and Minato Mirai night views are visible from it. Operating hours are 11 a.m. to 10 p.m., and tickets are bought with cash at the ticket booth below. There are separate lines for standard gondolas and clear gondolas with glass floors, and the gondolas sway when the wind blows.
