The Pokémon Company and Niantic have kicked off another second anniversary event for Pokémon GO in Japan. This event gives players in the region an opportunity to catch rare regional-exclusive Pokémon, such as Tauros in Los Angeles, Kangaskhan in Sydney, Corsola in Hawaii and Mr. Mime in London. For a chance at winning a prize pack, all you have to do is follow the official Japanese Twitter account for Pokémon GO and select one of the four Pokémon you want to catch by September 9, 2018. Winners will receive tickets to visit the actual locations for a chance to catch the rare Pokémon. To learn more about this event, click here.
