Hotel Keihan x The Promised Neverland

Hotel Keihan x The Promised Neverland was a collaboration between The Promised Neverland and Hotel Keihan which was held at six different locations in Japan and ran from June 1 to August 29, 2021. The collaboration featured six concept rooms nationwide with life-sized characters, animated setting pictures, original merchandise, voices from Emma, Norman, and Ray, and a mini exhibition. Due to the events popularity, original goods from the collaboration continued to be sold until March 31, 2022.

The rooms were divided into two themes, based on season one and season two of the anime series. Each room contained life-size character cutouts looming next to the bed, and annotated drawings of the characters displayed on the walls and around the room. The beds had cushions and covers inspired by the series. Guests were also given a goody-bag filled with original goods themed to the series such as a tote bag, slippers, a tumbler and key chain. The lobby also contains lots of character cutouts and a mini art exhibition featuring annotated drawings and concept art for the anime. The lobby also sold original merchandise for The Promised Neverland.
