Yokohama, Japan, is celebrating Honkai: Star Rail with a night time display of Aha on the Cosmo Clock 21 Ferris wheel, ahead of the character’s debut as the game’s first playable Aeon. The one-minute shows run every 15 minutes from 6:30 p.m. through November 10, 2026, with the last starting at 8:45 p.m. Weather or other circumstances may cause cancellations.

Running through November 15, it will feature character panels and Aha artwork.
Yokohama’s Cosmo Clock 21 Ferris wheel is featuring Aha in a nighttime display for the city’s Honkai: Star Rail collaboration. The display runs through November 10, just before Version 4.7 arrives on November 11 with Aha set to become the game’s first playable Aeon. A separate character exhibition at Hammerhead Park is scheduled to open on update day and run through November 15.
When to see the Cosmo Clock 21 display
The Ferris wheel display is part of Star Rail Trailblazing Game in Yokohama, a citywide collaboration. Its premise casts Aha as being on the run in Yokohama, with the character appearing on the wheel after dark. Cosmo Clock 21 is located inside Yokohama Cosmo World.
| Event | Dates | Location and timing |
|---|---|---|
| Aha Ferris wheel display | November 5–10, 2026 | Cosmo Clock 21, Yokohama Cosmo World; one-minute presentations at :00, :15, :30 and :45 between 6:30 p.m. and the final 8:45 p.m. presentation |
| Special exhibition | November 11–15, 2026 | Hammerhead Park; opening hours were not specified in the supplied details |
Visitors should plan around the one-minute showtimes, rather than expect a continuous Aha display throughout the evening. The last presentation begins at 8:45 p.m.; the announced schedule ends at 8:46 p.m. The display may also be canceled without notice because of weather or other circumstances.
A second event begins with Version 4.7
After the Ferris wheel display ends, the collaboration shifts to Hammerhead Park. The planned exhibition includes panels of characters from the Two-Phase Paradise arc and the Clear Sky Route Fluffy Ship, alongside a visual board depicting Aha. It opens November 11, the scheduled release date for Version 4.7 and the conclusion of that story arc.
That timing gives the Yokohama events a clear connection to the update: the Ferris wheel introduces Aha ahead of their playable debut, while the exhibition begins as the new version arrives. Players following the update itself also have a separately announced giveaway to look out for: a choice of one limited five-star character from a group of three, including Acheron
Other parts of the Yokohama campaign include Light Cone-themed photo spots and an original-card giveaway around the city. The available details do not specify their locations, participation requirements or whether they share the Ferris wheel and exhibition dates; visitors should check the collaboration’s event information before making a trip for those activities.
