4 new Pokémon Utility Hole Covers, or PokéLids (Pokéfuta ポケふた) were unveiled for Yokohama just ahead of the
2023 Pokémon World Championships. The new manholes feature Pikachu and are based on images of various landscapes in the prefecture. They will be installed at: Rinko Park, Yokohama Marine Tower, Nippon Maru Memorial Park and Aka-Renga Park.
Each PokéLids is an original design and each is unique with the aim of promoting the appeal of Pokémon and each region they are installed in throughout Japan.
The PokéLids that are installed will gradually become PokéStops for the location-based game Pokémon GO for smartphones.
