What this is
Themed around the mobile RPG 100 Sleeping Princes & the Kingdom of Dreams, this pop-up collaboration cafe transforms eeo Cafe in Ikebukuro into an immersive dining experience featuring character-inspired food and drinks. Reservations are required per time slot under a complete turnover system, and exclusive merchandise can be ordered via eeo Store for in-store pickup. Running for just under two weeks in August 2026, it's the kind of limited-run fan event that sells out fast.
Who should go
Fans of the 100 Sleeping Princes mobile game are the clear target here — casual visitors unfamiliar with the IP will find little to draw them in. Works well for solo fans or small groups who've pre-booked a time slot.
Good to know
Seat reservations and merchandise pre-orders are handled through eeo Store (eeo-store.jp) — foreign credit cards are generally accepted on the site but confirm at checkout. The cafe operates on a strict time-slot turnover system, so latecomers risk losing their booking. Menu items are subject to change or unavailability due to supply conditions, so don't bank on a specific dish being available. eeo Cafe is a specialist collaboration cafe venue in Ikebukuro, a neighbourhood well-known for anime and gaming culture, making it easy to combine with other fan-oriented shops nearby. Bring cash as a backup, as smaller themed cafes sometimes have card reader issues.
