I really doubt this list is complete, though I did my best to include as much as I could. If I find more stuff I’ll add it, and feel free to leave a comment if you can think of anything yourself!
Appearances in Nintendo Games
Game Boy Camera Japanese version has this picture in the B Album
Pikmin 2 had you collecting real-life items, including a hanafuda deck https://www.pikminwiki.com/Talisman_of_Life
Hanafuda is available to play in both Clubhouse Games …games (as well as Clubhouse Games Express: Strategy Pack and the Japan only like, reduced version of clubhouse games called Daredemo Asobi Taizen). In the DS versions, it is called Koi-Koi, as that is the actual name of the game, and hanafuda is the name of the cards.
This card shows up in Quite Puzzled microgame from the Japanese version of WarioWare: Touched! (It was replaced by a western playing card in the international versions)
One of 9-Volt’s microgames in WarioWare Gold is based on hanafuda https://www.mariowiki.com/Hanafuda
These hanggliders in Mario Kart Tour are based on a real deck Nintendo produced, see below

The entire 2014 book is based around hanafuda with many of Nintendo’s old toys drawn in hanafuda art, I highly recommend checking out the post at http://blog.beforemario.com/2014/05/a-closer-look-at-nintendos-2014-company.html to see all the photos! Here’s a sample
My Nintendo Europe offered postcards based on the Napoleon Mario deck (they also sold the deck itself at the same time) https://my.nintendo.com/rewards/70604724dabc9845
Nintendo themed Hanafuda Decks
You can find a list of hanafuda decks that Nintendo has produced here:
Of course, the best ones are the video game themed ones
We have the Mario Napoleon set
Better images at https://www.mariowiki.com/Mario_Hanafuda that link also pointed out these two promo images that have teeny little hanafuda cards, what a treat

More resources for the exceptionally interested
For more general information about hanafuda and where it’s showed up in video games over the years (and where I got a lot of info from) https://nintendo.fandom.com/wiki/Hanafuda
Both NoA and NoE have PDFs of how to play Koi-koi currently up on their websites:
https://www.nintendo.com/consumer/downloads/hanafuda_en.pdf – NoA
https://cdn02.nintendo-europe.com/media/downloads/other_1/my_nintendo_store_3/MyNintendoStore_Manual_Hanafuda_MarioCards_UKV.pdf – NoE
Play Nintendo Japan got a short webcomic about hanafuda
It has this cute art of Mario and Toad playing!
If you’re interested in Nintendo’s history with card games in general I recommend this post!
If you enjoy this stuff, I personally loved reading the Wikipedia article about karuta, which explains the many kinds of Japanese card games and where they came from : D https://en.m.wikipedia.org/wiki/Karuta
There’s a bunch of not Nintendo hanafuda video games floating around too, I’m not that concerned with them, but you can find lists here https://nintendo.fandom.com/wiki/Hanafuda or here https://www.giantbomb.com/hanafuda-card-games/3015-7399/games/ if you’re interested though. I support that decision.
Bonus non-Nintendo hanafuda sighting (this is my list I make the exceptions): The Hatsune Miku Project Diva games that have Close, Open, Demons and the Dead – In the music video, there are hanafuda cards scattered on the ground
Thanks for witnessing!
