The Nintendo Museum opened today in the company’s hometown of Kyoto, and it is already limiting some gift shop items to one per person in an attempt to discourage visitors from flipping exclusive merch online.

The two-story museum highlights the company’s history dating back to 1889, when Nintendo started making hanafuda playing cards. It also features interactive exhibits letting visitors play Nintendo games in unusual ways, including using oversized NES controllers and Wii Remotes that need two people to operate.

The Nintendo Museum announced through its official X account that several items will be limited to one per customer, including miniature controller keychain collections, neck straps, magnet collections, certain hanafuda card sets, and the controller-shaped cushions.

Nintendo already limits attendance to its new museum. Tickets can only be reserved online through a random selection process and have already all been claimed through the end of 2024.
