Serigaya Park in Tokyo has been replacing its manhole covers with Pokéfuta, or Pokémon designs, to boost local tourism. The Pokéfuta aren’t new; they’ve been around since 2018 but not in Tokyo and not in a place like Serigaya Park. And they’ve opted for Gen 1 Pokémon, likely because they’re more recognisable to people:
In contrast to other prefectures’ Pokéfuta, which feature the same species in multiple scenes, each of the Tokyo Pokéfuta’s characters are unique to their cover, though they all hail from the first-generation Kanto Pokédex (which is fitting since “Kanto” is also the real-life name for the eastern region of Japan that includes Tokyo). These are also the first Pokéfuta where humans can be seen, though it’s unclear if they’re Pokémon Trainers or just regular folks who came to hang out in the park and were lucky enough to encounter them randomly.
