The physical product is a Switch 2 game case that contains a download code for the Expansion Pass rather than a game card; pre-orders are available now through the local Nintendo Store.
According to the official Korean announcement, customers should expect a boxed package containing only a digital redemption code.
The statement clarified that the product does not include a physical cartridge and instructed buyers to redeem the provided code on the Nintendo eShop on their Nintendo Switch 2 consoles.
The announcement also reiterated that players must own the base Pokémon Pokopia software to access and play the additional Expansion Pass content.
The Expansion Pass program for Pokémon Pokopia began earlier this month with the release of the first content drop, Bubbly Basin, which launched alongside the free Version 2.0.0 game update.
Nintendo and The Pokémon Company have scheduled a second DLC installment for later in 2026, with a third part planned for 2027.
When Pokémon Pokopia originally launched earlier this year, Nintendo offered a Game-Key Card release option at retail.
The new Korean package follows that approach by providing a physical retail option for customers who prefer boxed purchases while still delivering the Expansion Pass as downloadable content via the Nintendo eShop.
Nintendo Korea's announcement does not indicate whether the code-in-a-box Expansion Pass will be distributed in other regions.
For now, the September 10 release and accompanying pre-orders apply to the Korean market only.
This release underscores a growing retail trend of boxed packages that serve as physical vessels for digital content on Nintendo Switch 2.
For owners of Pokémon Pokopia, the new retail Expansion Pass provides an alternative for buying DLC through standard retail channels while continuing to rely on Nintendo's digital infrastructure for redemption and delivery.
