Hanafuda is a deck, not a game. Koi-Koi, Hachi-Hachi, Oicho-Kabu and Go-Stop explained, plus why the 48 cards are arranged the way they are.
Most people outside Japan meet hanafuda through Koi-Koi, often in a video game. It is a reasonable introduction and it leaves a false impression, because hanafuda is not a game. It is a deck, the way a pack of 52 cards is a deck, and it plays many games with quite different characters.
Forty eight cards, twelve suits of four, one suit per month of the year. Each month has a plant.
Within each month the four cards are not equal. Most months hold two plain cards, one ribbon card and one animal or object card. Five months instead contain a bright, the highest class of card: the crane in January, the curtain in March, the moon in August, the rain man in November and the phoenix in December.
Crucially, no card has a number on it. Values exist in the players' heads and change from game to game. That is not decoration, it is history.
Portuguese traders brought numbered playing cards to Japan in the sixteenth century, and they were adopted enthusiastically for gambling. The authorities banned them, repeatedly, across the Edo period. Each ban was followed by a new design that avoided the letter of the prohibition, and the cycle ran for two centuries.
Hanafuda is where that cycle settled. Pictures, no numbers, values known only to players. A deck that is difficult to legislate against because it does not look like what was banned. Nintendo was founded in Kyoto in 1889 to manufacture exactly these cards, and still makes them.
The deck's design is a record of an argument with the law that lasted two hundred years.
Cards are matched by month: play a card from your hand to capture a table card of the same month, then flip from the deck and match again. Captured cards build scoring combinations called yaku, such as three brights, the boar deer butterfly set, or a run of ribbons.
The decision that gives the game its name comes after you complete a yaku. You may stop and bank the points, or call koi-koi, meaning come on, and keep playing for more, with the risk that your opponent completes their own yaku and takes the round instead. It is a pressing your luck game wrapped around a matching game, which is why it stays interesting long after the matching becomes automatic. Our full rules are in Hanafuda Koi-Koi rules and strategy.
The name means eighty eight, the target score. Hachi-Hachi is the older and more elaborate game, played by three with a scoring system built on card point values, twelve per bright, ten for animals, five for ribbons and one for plain cards, plus a large set of yaku and side payments between players.
Where Koi-Koi is a duel with one big decision, Hachi-Hachi is a longer negotiation with continuous ones. It was the serious hanafuda game for generations and remains the one traditional players point to when Koi-Koi is described as the national game.

Players aim for a hand totalling nine, counting only the last digit of the sum, so nineteen scores nine and twenty scores zero. It is closer to baccarat than to Koi-Koi, fast and heavily associated with gambling. Its vocabulary gave Japanese the word yakuza, from the losing hand eight nine three.
Korea adopted the deck as hwatu, fire cards, and its game Go-Stop is played by more people than any Japanese hanafuda game. The core matching is recognisable to a Koi-Koi player, but the scoring is more intricate and the social conventions, including penalties that shift points between players, give it a different texture. Anyone who learns Koi-Koi can pick up the basics of Go-Stop in an afternoon and will then spend a long time learning the scoring.
The deck has three qualities that keep it alive. The cards are beautiful, which matters more than game designers admit. The matching core is learnable in five minutes, so a new player is playing rather than studying. And the scoring layer is deep enough that experienced players are making real decisions in a game a child can join.
That combination of shallow entry and deep interior is the same pattern found in the other Japanese classics. Go has four rules and a lifetime of study, as covered in Go vs chess. Karuta is matching cards at speed and becomes a competitive sport, described in competitive karuta explained. Riichi Mahjong layers scoring on tile matching, in Riichi Mahjong rules.
The free ebook The Mind Games of Japan, included with MyRin on iOS and Android, covers Hanafuda alongside Go, Shogi, Mahjong and Karuta with complete rules and their history: see what is inside the ebook.
A Japanese deck of 48 cards divided into twelve suits of four, one suit per month, each represented by a flower or plant. The cards carry pictures rather than numbers, and different games assign them different values.
Because of gambling prohibitions in the Edo period. Western style numbered cards were banned repeatedly, and the flower deck emerged as a picture based alternative whose values live in the knowledge of the players rather than printed on the card.
Koi-Koi for two players is the best known in Japan. Hachi-Hachi is the traditional three player game. Oicho-Kabu is a fast counting game using the deck like a numbered one. Go-Stop is the Korean relative and the most played of all by number of players.
Yes. Nintendo was founded in 1889 in Kyoto to make hanafuda, decades before it made video games, and it still produces the cards today.
