PokéPark Wii: Pikachu's Adventure comes to Wii U eShop in Japan
Wii games available for download on the Wii U eShop can be played from the Wii U's Home Menu, without Wii Mode (unlike Wii games on game discs). PokéPark Wii: Pikachu's Adventure was originally released for Wii in Japan on December 5, 2009.
PokéPark Wii was released on the Wii U eShop in Japan alongside Resident Evil 4: Wii Edition and Resident Evil: The Umbrella Chronicles, meaning that all Wii games released on the Wii U eShop that were released in North America or Europe have now been released in Japan (except Metroid Prime: Trilogy, which was never released in Japanese as a compilation, only as individual games).
PokéPark Wii was released on the Wii U eShop in Europe and Australia on July 16, 2015 and in North America on May 19, 2016.
