In the Kaiji manga, the “Minefield Mahjong” arc uses a variation of Japanese Mahjong. It can be read without knowing the general rules (as I did), but I guess they make some of the scenes more understandable and/or impactful. Maybe I’ll give it a reread after checking this out.

There are entire manga/anime centered around Mahjong, like Saki and the multitude of spin-offs. And there's many more than just those.

If you have a Nintendo Switch, Clubhouse 51 games includes a pretty decent Riichi Mahjong mode that'll explain all the rules too.

The kaiji author is a massive riichi fanatic if I recall correctly.

Yes, he is! (Which explains other of his mangas, Akagi):

> He has been playing mahjong since junior high school days, and admitted that though he has rarely lost a game when he was in school, his current level of ability is average. According to him, he has "tournament luck" and has even won mahjong tournaments between mahjong manga artists. He has also participated in professional mahjong matches. He played about two games against Akagi and Kaiji's voice actor Masato Hagiwara, who is known as one of the best mahjong players in the entertainment industry, and made Hagiwara say "I don't think I can beat him."

If you want to read manga for mahjong I'd say go straight for Akagi and Ten, by the same author. Akagi has a great anime adaptation that covers the first third. Both are excellent mangas in their own right, with or without understanding mahjong.

Tereré is also a milder alternative: https://en.wikipedia.org/wiki/Terer%C3%A9

I love terere - note you will get less caffeine and antioxidants from cold brewing.

> They have made a sugar free version now as well, but that not as cool as making your own

That version (Club Mate Zero) is hard to get in supermarkets as well, at least where I’m living in Germany. I usually order it online.

Club Mate has a different taste than traditionally brewed yerba mate. It’s carbonated as well.

Look for “mate cocido”. La Tranquera is the brand I use.
