The Pokémon GO Fest 2022 Sapporo takes place from August 5th, 2022 to August 7th, 2022 in Nakajima Park, Sapporo, Japan. Tickets cost 3,000 yen (tax included) and there is an additional 1,200 yen add-on. As most players will be unable attend this event in-person due to Japan limiting the number of tourists that can visit the country, Niantic will also be holding a Global Challenge and Ultra Unlock.
