NIJISANJI’s "3SKM" Collaborates with Yokohama Cosmo World! Exclusive Goods with New Visuals and a Stamp Rally Featuring Yusei Kitami, Kaisei, and Ness Sakaki

The first-ever collaboration campaign between the NIJISANJI VTuber unit "3SKM" and the urban multi-level amusement park "Yokohama Cosmo World" will be held starting Saturday, May 2, 2026.

In this campaign, the three members—Yusei Kitami, Kaisei, and Ness Sakaki—will appear throughout the park in various ways. Two patterns of visuals, "~Daytime ver~" and "~Night ver~," have been newly illustrated for this project. The event will feature a wide range of interactive content, including special displays across the park, a kitchen car with an original menu, and a stamp rally. Furthermore, a tie-up project with "YOKOHAMA AIR CABIN" and limited-edition prizes at "namco" amusement facilities nationwide have also been confirmed.
