The short answer
Hanafuda (花札, "flower cards") is a Japanese deck of 48 cards — twelve months, four cards each — that you read entirely by their pictures. Koi-Koi is the beloved two-player game: match cards by month to capture them, build scoring sets called yaku, then make the game's one delicious decision — bank your points, or shout こいこい ("come on, come on!") and gamble for more. Start with Nintendo's Daitoryo for the real thing, the Mario deck for pure joy, or a Hanafuda Hawaii deck for beauty on a budget.
Come in, come in — leave your shoes by the door. (I have been waiting to show you this one.)
Hanafuda has a reputation for being impenetrable, mysterious, only-for-the-initiated. I am here to tell you that reputation is nonsense, and a little bit on purpose — the cards were designed to look secret. But between us? You will be playing a real round within fifteen minutes, and falling down the rabbit hole within fifteen days. I have set the whole table for you: what the cards are, how こいこい actually unfolds at speed, the yaku worth chasing, the hot opinions that will make you sound like you've played for years — and which deck to actually buy. Sit. ❀
What even is hanafuda? (a tiny, scandalous history)
Hanafuda — 花札, literally "flower cards" — is a deck of 48 small, stiff cards split into twelve suits, one per month, each named for a seasonal flower. No numbers. No letters. You read every card by its painting, which is exactly the point.
Here's the deliciously petty origin story: Japan banned card games again and again across the 17th and 18th centuries, mostly to stamp out gambling. So designers got cheeky — they hid the gambling decks inside innocent little flower pictures the authorities couldn't pin down. Cat and mouse, for a hundred years. And the maker who eventually won that game? A tiny Kyoto company founded in 1889 to print hanafuda by hand. You may have heard of it. Nintendo. Yes — that Nintendo started as a flower-card company, and still prints these today.
Mario got his start, in a very real sense, dealing cards in the back room.
How you actually play こいこい
Koi-Koi is a two-player duel over a shared field of face-up cards. The whole engine: match by month to capture. Two cards of the same month? Yours.
Deal 8 to each player, 8 face-up to the field, stack the rest face-down. On your turn you do this twice — once from your hand, once from the deck:
Play one card. If it matches a field card's month, scoop both into your pile. If nothing matches, you must leave your card on the field (this hurts — you're feeding your opponent). Then flip the top of the draw pile and do the same. Two captures a turn, if you're lucky.
The magic is the moment a capture completes a yaku — a named scoring set. The game stops and looks at you. Bank it now (勝負 / shōbu, "I win this round"), or whisper こいこい and keep playing for something bigger. The name means "come on, come on" — the dare you make to yourself.
The twelve months, as a garden (not a spreadsheet)
Here is your whole year at a glance — twelve little gardens, each with its flower and its special cards. The five Brights glow gold; learn their faces first, because nearly every big hand runs straight through them.
How to actually win: the strategy nobody tells beginners
Here is where most guides leave you, and where the real game begins. Two truths to tattoo on your heart:
One: stop chasing the legendary hands. Gokō (五光), all five Brights, is gorgeous — and it shows up in fewer than 2% of rounds. Inoshikachō (the boar-deer-butterfly) lands maybe 8% of the time. The players who actually win grind the humble stuff: five animals (tane), ten chaff (kasu), the ribbon sets. Small, steady, doubled-when-it-counts.
Two: koi-koi is a knife that cuts both ways. When you call it and your opponent completes any yaku before you score again — they win the round, their score doubles, and you get nothing. So the call isn't about greed. It's about board state: call koi-koi only when the field still has cards that build YOUR hand and starve theirs.
Goko is the dream you frame on the wall. Tane-and-kasu is the rent you pay every month.
Down the rabbit hole: the deck you buy is only the beginning
A confession about why I love this little game so much: hanafuda is a collector's world wearing a card game's clothes. The moment you have one deck, you want the Nintendo Museum exclusive Phoenix set. Then you're framing decks on your wall, buying stencil-coloured artisan packs, hunting the cobalt-blue Korean cousin — hwatu, 화투 — that plays the same twelve months in a bolder palette.
And then there's the part that undoes me every time: people make these. Partners hand-painting custom decks as anniversary gifts. Pokémon decks, Avatar decks, decks designed so the Brights literally shimmer so newcomers can spot them. This is a community that turns a 48-card deck into a love letter. Come for koi-koi; stay for the people. ❀

4 photos · swipe Nintendo Hanafuda Cards — Daitoryo
If you want the deck a Japanese player would actually own, this is it. "Daitoryo" means "President," and the box famously carries a portrait of Napoleon — a quirk Nintendo has kept for over a century. The cards are thick, sturdy, and unillustrated in the classic style, so you learn the real images rather than a stylized version. Available with red or black backs at the same price.
- The genuine, time-honored design players grow up with
- Nintendo's hallmark card stock — stiff, snappy, durable
- Forces you to learn the true card art, which transfers to any deck
- Traditional faces are austere; no scoring hints printed on the cards
- Often sold via specialty importers, so prices vary
2 photos · swipe Hanafuda Cards — Mario™ (Red)
Nintendo reimagines all 48 cards with Mario, Luigi, Peach, Yoshi and friends woven into each month — and somehow it stays true to the traditional structure, so it plays exactly like a real hanafuda deck. It ships with a hard plastic storage case and an instruction sheet, which makes it a lovely first deck for a household with children. Street prices typically run around $30 through importers; I have left the figure unset because the official store does not publish a fixed price and third-party listings vary widely. A black version exists too.
- Genuinely playable — faithful to the 48-card / 12-month structure
- Includes a hard case and printed instructions
- The most welcoming deck for newcomers and kids
- Pricing is inconsistent across importers; verify before buying
- Character art makes a few months harder to read as 'flowers' at first
4 photos · swipe Hanafuda Nā Pua Hawaiʻi
Hawaii has played hanafuda for over a century, and this modern deck honors that with artwork of indigenous and canoe plants, birds, and moʻolelo of the islands. It is inexpensive, in stock, and quietly gorgeous — the kind of deck that starts conversations. A wonderful choice if you want something distinctive without artisan pricing.
- Striking original Hawaiian-island artwork
- Among the most affordable real decks available
- Reliably in stock and ships from a small, dedicated maker
- Reimagined art means the imagery differs from the classic Japanese cards
- Not the deck to learn from if you want strict traditional fidelity
4 photos · swipe Hanafuda Pilina
Pilina pairs the 48-card hanafuda structure with images of indigenous and invasive species of the Hawaiian Islands — native beside non-native — turning each round into a quiet lesson as well as a game. Beautifully produced, well stocked, and full of meaning. A lovely step up from Nā Pua if a deck with a message appeals to you.
- Full 48-card playable deck with a genuine ecological theme
- Modern, polished production
- Deeply in stock
- Slightly pricier than the maker's other decks
- Themed art, like all reimaginings, departs from the traditional images
4 photos · swipe Hanafuda Hawaii Style (Extra Large)
These 48 cards are roughly twice the size of standard hanafuda and — the truly kind touch — print the points, suit, and yaku right on each card's face. For an absolute beginner that is enormously reassuring; you can play a full round without once glancing at a chart. Note that it can sell out, so check availability before you set your heart on it.
- Points and yaku printed on every card — the gentlest possible on-ramp
- Oversized cards are easy to handle and read aloud
- The lowest price of any deck here
- Often out of stock
- Large size and on-card hints are training wheels you will eventually outgrow

Questions, answered
Is hanafuda hard to learn?
No. You only need to recognize four card ranks — Brights, Animals, Ribbons, and Chaff — and one rule: match cards by month to capture them. Most people are playing a real round of Koi-Koi within fifteen minutes. The depth comes later, from the koi-koi gamble, not from the basics.
How many cards are in a hanafuda deck?
Exactly 48: twelve months (suits), four cards in each. Unlike a Western deck there are no numbers or letters — you identify every card by its picture.
What does "koi-koi" actually mean?
It means roughly "come on, come on" — the call you make when you have a winning set but choose to keep playing for a bigger one. It is a dare to yourself, and the risk is real: if your opponent finishes first after you call it, their score doubles and you get nothing.
How many players do you need for Koi-Koi?
Two. Koi-Koi is specifically a two-player hanafuda game. For more players, the same cards are used for other games such as Hachi-Hachi, but for your first sessions, find one partner and play Koi-Koi.
What is a yaku?
A yaku is a named scoring combination of captured cards — for example, the three Brights (Sankō), or the Boar-Deer-Butterfly trio (Inoshikachō). You score every yaku you complete, and their points add together. Forming one is what gives you the right to stop the round or shout koi-koi.
Which is the best hanafuda deck for a complete beginner?
If price is no object and you want the real cultural object, the Nintendo Daitoryo. If you want the easiest possible start, the Hanafuda Hawaii Style deck prints the points and yaku right on the cards. And the Mario deck is the most joyful gift — fully playable, with a case and instructions included.
Does the Nintendo Mario hanafuda deck play like a real deck?
Yes. Nintendo kept the traditional 48-card, twelve-month structure intact and simply illustrated each card with Mario-universe characters, so it plays identically to a classic deck. It also ships with a storage case and an instruction sheet.
Are the point values the same in every ruleset?
Mostly, but not perfectly. The values here follow the common standard (Gokō 10, Shikō 8, Ame-Shikō 7, Sankō 5, and so on), which matches Nintendo's own rule sheets. A few house rules differ by a point — most often scoring Sankō at 6 — and many groups apply a doubling when a round totals 7 or more. Agree on the rules before you deal.
What's the difference between hanafuda and Korean hwatu (화투)?
They're cousins. Hwatu uses the same twelve-month, 48-card structure but with a bolder, glossier plastic finish and is hugely popular in Korea (especially the game Go-Stop). If you love the koi-koi rhythm, a hwatu deck is a gorgeous, slightly punchier way to play the same garden.
Should I really chase Gokō (the five Brights)?
Almost never on purpose. It appears in under 2% of rounds. Treat it as a happy accident — keep capturing Brights when they're cheap, but build your actual score from animals, chaff, and ribbon sets. Greatness in koi-koi is mostly good bookkeeping.
Yumi's verdict
Begin where your heart is. If you want the genuine article — the deck a Japanese player grew up with — buy the Nintendo Daitoryo and learn the true card faces; everything you learn on it transfers everywhere. If this is a gift, or there are children at the table, the Mario deck is pure delight and plays exactly like the real thing. And if you simply want to start tonight, with the gentlest possible welcome, a Hanafuda Hawaii deck — Nā Pua for beauty, or the Extra-Large Style deck with the yaku printed right on the cards — will have you playing your first round of Koi-Koi before the tea has cooled. There is no wrong door. Come in.
