What this is
Sleep inside the Demon World Hotel — a fully themed immersive room at Shinjuku Prince Hotel where Iruma and his friends appear in hotelier uniforms to welcome you as part of a collaboration with the anime *Welcome to Demon School! Iruma-kun*. The room features hidden characters that only reveal themselves under black light, Dolby Atmos-compatible speakers, lighting effects, and a 75-inch smart TV that immerses you in the series' world. Every overnight guest receives an exclusive novelty set including three character acrylic stands, a logo clear pouch, and an original key card — plus a newly recorded voice message from Iruma Suzuki performed by voice actor Ayumu Murase.
Who should go
Fans of the anime who want more than merchandise — this is for people who want to actually sleep inside the show's world. Works well for couples or solo travellers willing to pay a premium for the single-occupancy experience.
Good to know
Bookings are best made through Rakuten Travel, which typically offers the lowest rates for Japanese hotels and accepts foreign credit cards. Shinjuku Prince Hotel is a well-known mid-to-upper-range city hotel with a straightforward check-in process — front desk staff generally have basic English capability. The immersive room is a standard hotel room transformed with themed décor, lighting, and AV equipment, so expect hotel-room scale rather than a theme-park installation. The novelty set — acrylic stands, clear pouch, and key card — is handed out at check-in and is exclusive to this plan; it cannot be purchased separately. If you want the exclusive voice message experience, bring your own headphones for the best Dolby Atmos audio quality through the in-room speakers.
