You’ve probably seen them in a Nintendo history documentary or maybe an anime. Those tiny, thick, plastic-coated cards that look more like dominoes than a deck of Hoyle. They’re beautiful. They’re also, honestly, a bit intimidating if you’re used to Kings, Queens, and Aces. Hanafuda—which literally translates to "flower cards"—is less about math and more about pattern recognition and seasonal vibes.
Most people think learning how to play hanafuda requires memorizing a massive encyclopedia of Japanese botany. It doesn't. You just need to know how to match a Pine to a Pine and a Cherry Blossom to a Cherry Blossom.

Forget what you know about poker or bridge. There are no suits like hearts or diamonds here. Instead, the deck is split into 12 months, with four cards representing each month. It’s a game of "fishing." You play a card from your hand, match it with one on the table, and haul them both into your "point pile." Simple? Sorta. The complexity comes in the scoring, which is where most beginners get stuck.
The Deck: 48 Cards of Controlled Chaos
The first thing you’ll notice is that the cards are small. Like, really small. If you bought a deck from Nintendo (who, fun fact, started as a Hanafuda company in 1889), they’ll be stiff and have a satisfying "thwack" when you slap them down.
There are 48 cards. Each month has a specific flower or plant. January is Pine. February is Plum Blossom. March is Cherry Blossom. You don’t need to be a botanist to play, but you do need to recognize the art style. For example, November (Willow) looks like a rainy, abstract mess compared to the clean lines of August (Susuki Grass).
Instead of numbers, cards fall into four "point" categories. There are the Lights (the big scorers, usually featuring a sun or a crane), the Tane (animals or objects like a bridge or a butterfly), the Tanzaku (colored poetry ribbons), and the Kasu (the "junk" or "dregs" that only give you points if you collect a ton of them).
Understanding the hierarchy is everything. You might be tempted to go for the pretty ribbons, but if your opponent is quietly hoarding the Brights, you’re in trouble.
Starting a Game of Koi-Koi
While "Hanafuda" refers to the deck, the most popular game played with it is Koi-Koi. It’s usually a two-player showdown.
To start, you deal eight cards to your opponent, eight to the "field" (face up in the middle), and eight to yourself. The remaining cards stay in a draw pile. If you’re playing by the traditional rules, the dealer is called the "Oya" (parent) and the other player is the "Ko" (child).
On your turn, you do two things. First, you take a card from your hand and see if it matches any month currently on the field. If it does, you put your card on top of it and set both aside in your personal scoring area. If it doesn’t match, your card just sits on the field, lonely and waiting. Second, you flip the top card of the deck. Again, if it matches something on the field, you take the pair. If not, it stays out there.
This "hand-match, deck-match" flow is the heartbeat of the game. It’s fast. You’ll find yourself groaning when the deck flip gives your opponent the exact card they needed to finish a high-scoring set.
The "Koi-Koi" Gamble: Why the Game is Addictive
Here is where the strategy gets spicy. In many card games, the round ends the second someone hits a winning hand. Not here.
When you complete a "Yaku" (a scoring combination), you have a choice. You can yell "Stop!" to end the round and take your points. Or, you can shout "Koi-Koi!"

"Koi-Koi" basically means "Come on" or "Let’s keep going." You’re betting that you can build an even bigger hand before your opponent finishes any combination. If you call Koi-Koi and then your opponent completes a tiny, 1-point ribbon set and calls "Stop," you get nothing. Zero. Zilch. You’ve been "robbed."
It’s a game of pure greed and calculated risk. I’ve seen players lose entire matches because they tried to go for a "Five Brights" hand when they should have just taken the "Three Brights" and run.
Common Winning Hands (Yaku) to Memorize First
Don't try to learn all the Yaku at once. Focus on these three, as they are the easiest to spot:
- Ino-Shika-Cho: The Boar, the Deer, and the Butterfly. It’s worth 5 points and is probably the most famous hand in the game.
- Sanko (Three Brights): Any three of the "Light" cards (except the Willow Man, usually). This is your bread and butter for a quick win.
- Tane (Animals): Collect five animal or "feature" cards. Each extra animal after five adds another point.
What Most Beginners Get Wrong
People often treat Hanafuda like it’s a game of luck. Sure, the deck flip is random, but the "fishing" is tactical.
The biggest mistake? Ignoring the "Kasu" (Junk cards). If you collect 10 of these plain flower cards, you get 1 point. Every junk card after that is another point. It sounds pathetic, but a "Junk" win is the ultimate defensive move. It stops your opponent from finishing a 10-point masterpiece. It’s the equivalent of a "bunt" in baseball. Not flashy, but it wins games.
Another thing: the Willow month. The November cards are weird. One of them is a "Bright" card featuring a man with an umbrella (Ono no Michikaze). In some regional rules, this card is a "wild card" or has specific quirks. Most beginners see the messy lines of the Willow cards and get confused. Just remember: Willow matches Willow.
Setting Up Your First Match
If you’re looking to actually learn how to play hanafuda today, don't just read the rules—do a "dry run."
Lay out the cards by month. There are 12 rows of 4. Look at the January Pines, the February Plums, and the March Cherries. Notice that each month usually has two "junk" cards and two "special" cards (either a ribbon, an animal, or a bright).

Once you can distinguish July (Bush Clover) from October (Maple), the game speeds up significantly.
The scoring can feel math-heavy at first because many people play over 6 or 12 "months" (rounds). You keep a running tally. If you win a round after calling Koi-Koi, your points for that round are often doubled. This leads to massive swings in the leaderboard. One minute you’re winning, the next you’re 20 points in the hole because you got greedy.
Actionable Steps for Mastery
To move from a confused beginner to someone who can actually hold their own in a match, follow this progression:
- Download an App First: Seriously. Playing digitally handles the "legal moves" for you. It will highlight which cards match, allowing you to focus on the patterns rather than the mechanics. The "Hanafuda Koi-Koi" apps by developers like bitsmith or even the Nintendo Switch "51 Worldwide Games" version are excellent for this.
- Focus on the "Blue" and "Red" Ribbons: There are three purple/blue ribbons and three red ribbons with writing on them. If you get all three of either set, that’s 5 points. It’s an easy target for beginners because the ribbons literally stand out against the flowers.
- Watch the Field, Not Just Your Hand: If you see a "Bright" card on the field (like the Full Moon or the Crane), and you have a matching month card in your hand, take it immediately. Don’t wait. Your opponent is looking at that same Moon card.
- Learn the "Monthly" Rule: Some house rules give you extra points if you match the cards belonging to the current real-world month. It’s a nice bit of flavor that adds a tiny bit of extra strategy to card valuation.
Hanafuda is a slow burn. It’s a game of aesthetics and nerves. Once you stop seeing "pretty flowers" and start seeing "strategic point-capture opportunities," you’re hooked.
Grab a deck—preferably a heavy, "stiff" plastic one—find a friend, and start fishing. Just remember: if you're feeling lucky, shout "Koi-Koi," but don't blame the cards when it backfires.
