Disney's been dealing with Nintendo since Walt was alive.
Nintendo started off as a playing card company in 1889. In the 1960s, they cut a deal with Disney to produce
licensed card decks and board games with the Disney characters and the results boosted Nintendo's sales significantly.
When Nintendo got into video games and made the Game and Watches, the only outside licenses that ever got produced were Mickey and Snoopy.
There have been numerous Japanese developers making Disney games like Capcom, Square, and Sega and indeed, even Nintendo got into the act on occasion (image example's technically a Rare game, but this was back when Nintendo owned them). There's been quite a few Nintendo-exclusives over the years and even the original Epic Mickey's Japanese localization was published by Nintendo themselves, supposedly even involving some camera tweaks.
On the other hand, there was that terrible Nintendo related thing Disney themselves made back in the 90s.
