Ok, first of all, a warning. The following may result in a sensory overload of your kawaii senses. Now with that out of the way, Yokohama Minatomirai is host to an annual Summer event called Pikachu Outbreak! The event runs between August 9 through to the 17th. Over 1000 Pikachus take over several landmarks from museums, restaurants and the Cosmo Clock 21Ferris wheel, to name a few. Even the Yokohama Red Brick Warehouse was temporarily turned yellow as 50 electric mice ran rampant.
The upcoming Pokemon movie, Pokémon the Movie: Diancie and the Cocoon of Destruction, enjoyed the cross promotion with Rica Matsumoto, a voice actress, being present as well as Konno Asami, an ex-idol who’s now a TV presenter. Here’s a beyond cute Vine video showing the Pikachu shenanigans!
