Pokémon Sleep and the villa-sharing service NOT A HOTEL announced a collaboration on September 1, 2026 that turns the game's sleep premise into a physical stay. The campaign, called 'Stayable Poké Ball,' will place a Poké Ball-themed hotel named Poké Ball-Themed Hotel somewhere in Hokkaido. Only winners of a lottery campaign can book the stay; the hotel will not be open to the general public during the campaign period. Application methods and full details, including the interior, are scheduled for release on September 15, 2026. The announcement video shows a bed-equipped house shaped like a Poké Ball set in a forest, with a rear door and a large window. The collaboration is one of several 'Pokémon × sleep' initiatives unveiled at the Pokémon 30th anniversary sleep announcement event held in Tokyo the same day. Pokémon Sleep, released in July 2023 for iOS and Android, surpassed 30 million cumulative downloads worldwide as of April 26, 2026. NOT A HOTEL, founded in 2020, sells shared ownership of villas designed by architects and creators.
The collaboration was unveiled at the 'Pokémon 30th Anniversary, Sleep Announcement Event' held in Tokyo on September 1, where Pokémon COO Taketo Utsunomiya introduced the company's health care initiatives. The event also presented results from the National Sleep Prefecture Grand Prix 2026, which ranked Miyazaki Prefecture first overall based on sleep data from about 43,000 Pokémon Sleep users.
NOT A HOTEL, the company behind the stay, launched in 2020 and sells shared ownership of villas designed by architects and creators. Its portfolio includes the BIG-designed NOT A HOTEL SETOUCHI, which opened on Saziki Island in Hiroshima Prefecture in April 2026, and the upcoming NOT A HOTEL TOKYO THE NIGO HOUSE directed by NIGO. The campaign's catchphrase, 'This Poké Ball, you can really stay in it,' accompanies footage of a Poké Ball-shaped house with a bed, a rear door, and a large window set in a forest. The hotel's exact location is given only as 'somewhere in Hokkaido,' and the interior design has not yet been shown.
