What this is
Grand Blue Dreaming POP UP SHOP & Beer Festa 2026 is a themed pop-up event celebrating the broadcast of Season 3 of the TV anime Grand Blue Dreaming, held at Tobu Department Store Ikebukuro from July 8–20, 2026. Grand Blue Dreaming is a beloved comedy manga and anime series centered on diving club life, friendship, and — above all — drinking, making beer and sake a natural fit for this event. The pop-up shop sells exclusive merchandise including acrylic stands, bottle opener can badges, instant photo-style cards, cheers towels, and T-shirts, while the 8F Beer Festa runs alongside it offering collaboration alcoholic and non-alcoholic drinks. A special outdoor deck photo spot recreates the world of the series, and customers who purchase collaboration drinks receive a 'Drinking Declaration Form' as part of the venue-linked 'PaB-Style Bar Hopping' project. Exclusive 'Grand Blue sake' is also available for purchase, tying directly into the series' iconic drinking culture.
Who should go
This event is ideal for fans of Grand Blue Dreaming who want to celebrate Season 3 with themed merchandise and drinks in a fun, social atmosphere. The beer and sake collaboration angle makes it especially appealing to adult anime fans who enjoy the series' drinking-comedy premise. The outdoor photo spot and collectible goods will appeal to figure collectors and casual fans alike, and the non-alcoholic drink options mean non-drinkers aren't left out. Arrive early on weekends and public holidays, as numbered tickets may be distributed during busy periods — weekday mornings are your best bet for a relaxed visit.
Good to know
Entry to the pop-up shop is free, but numbered tickets may be issued on busy days — arriving at opening time (10:00 AM) is the safest approach, especially on weekends, public holidays, and the final weekend of July 18–20. The Beer Festa on the same floor runs later hours until 10:00 PM, making it a great option for an evening visit when the merchandise area is less crowded. Tobu Department Store Ikebukuro is directly connected to Ikebukuro Station, so access is extremely convenient regardless of which train line you use. Payment at department store event halls typically accepts major credit cards including foreign-issued Visa and Mastercard, though small drink purchases at the Beer Festa counter may prefer cash — carry some yen to be safe. Merchandise from this event is also available via the Fuuuu Online Shop if items sell out in person.
