Ireisu to host large-scale collaboration at LaLaport TOKYO-BAY

The 2.5D idol group Ireisu, managed by VOISING, will hold a large-scale collaboration campaign at Mitsui Shopping Park LaLaport TOKYO-BAY and LaTerrace TOKYO-BAY from September 14 to September 23, 2026.

The event features immersive decorations in the food court and throughout the facility, along with digital signage playing summer tour promotional videos and special BGM broadcasts including exclusive announcements. Fans can participate by writing messages on a special “support board,” which will be delivered to the dressing room entrance during the group’s Chiba performances at LaLa arena TOKYO-BAY on September 21 and 22.

Additionally, customers who spend 1,500 yen or more at participating stores can receive limited-edition clear bookmarks featuring summer tour visuals on a first-come, first-served basis.
