The Pokémon Company has announced a special Chansey distribution event for Pokémon Let’s Go Pikachu and Let’s Go Eevee via Pokémon Centers in Japan. From November 16, 2018, players who visit an actual Pokémon Center location during their birth month will be able to receive a secret code to unlock Chansey in either version of the game. There’s currently no word on how long this distribution will last, but stay tuned for any updates.
