The collaboration, officially titled Chiikawa Starry SKYTREE and the Secret Island, spans the tower’s two primary observation levels. Visitors to the 450-meter-high Tembo Galleria will encounter original character visuals and themed decor, while the 350-meter Tembo Deck will host special screenings via the SKYTREE ROUND THEATER, turning the tower's expansive windows into a panoramic display. The exterior of the 634-meter structure will also receive a custom lighting treatment inspired by the series' cast.

Beyond the visuals, the event includes a dedicated cafe menu and exclusive merchandise. Access to the themed menu at the Tembo Deck Floor 340 cafe requires a specific observation deck admission ticket bundled with a meal voucher. Prospective visitors should consult the official event website for purchase instructions, as the organizers have implemented strict prohibitions against ticket resales to manage access. This event marks a significant push by TOBU TOWER SKYTREE to draw international travelers to the landmark during the film's release window.
