The Pokémon Company has teamed up with SoftBank on a massive Pikachu-themed campaign for the spring for Pokémon fans in Japan. Participating SoftBank locations are now hosting a bunch of events throughout the season featuring various Pokémon prizes, as well as giving visitors an opportunity to take a picture with Pikachu. Those with a SoftBank plan can receive a Pikachu study book; while new subscribers can receive decorative stickers featuring designs based on Pikachu and a Poké Ball.
