Nintendo was a century-old family business making some of the best playing cards in Japan; when the old CEO was about to pass the baton to his descendent, the latter took a trip to the world headquarters of Bicycle, the biggest playing-card manufacturer in the world, and was shocked to see it was like two floors of a generic office building, and decided immediately to pivot the company into a bigger pond.
You can still buy Nintendo made playing cards. Their hanafuda cards are pretty decent, can be gotten on Amazon, and feel good to play with. Occasionally if you look on ebay you can still find JAL/Nintendo trump decks.
If you've got a Japanese coworker who likes traveling from Japan to your area, or a remailer service you trust, Nintendo sells a mahjong set on their spare parts store in Japan.
