The Pokémon: Let's Go! games take place in the Kanto region.
Pokémon: Let's Go, Pikachu! and Pokémon: Let's Go, Eevee! revisit the setting of the original Pokémon Red, Green, Blue, and Yellow games. Kanto includes familiar locations such as Pallet Town, Viridian City, Pewter City, Cerulean City, and Indigo Plateau.
The games are modernized versions of Pokémon Yellow, with Pikachu or Eevee serving as the player's prominent partner. Their journeys follow the classic Kanto adventure: collecting eight Gym Badges, battling Team Rocket, and challenging the Elite Four.
A common mix-up is confusing Kanto with Johto, the neighboring region introduced in Pokémon Gold and Silver. Although the Let's Go games connect to the wider Pokémon world, their main adventure is set entirely in Kanto.
