There's an all-new festival in Yokohama that's been attracting kids and adults since 2014 and there's nothing else you can see there but a bunch of Pikachus roaming around the city.
The festival called 'Odoru? Pikachu Tairyou Hassei-chu!' (Will they dance? Pikachu Outbreak!) is a week-long event featuring up to 1,000 Pikachus marching, dancing, and greeting all those who've made time to see them.
