If the player of the 5-5-5-5 now begins with (say) a pair of 6's, this can be beaten by 4-4 or 3-3 (the highest pair), but not by 8-8. The reversed order stays in effect until the end of the hand, unless another 4 of a kind is played, in which case there is a counter-revolution and the original order is restored.

You’ll see I first wrote the Japanese numbers in kanji but included how to read them in hiragana and romaji (English characters) as well.

The Japanese number system can be quite complex, especially when you first start learning.

While basic counting in Japanese is easy, there are several ways to count… even just to 10. And counting objects can become confusing because of a dreaded thing called “counters”.

But I’m here to help guide you through it! I’ll share all my best tips for counting in Japanese and tricks for getting around some of the difficult parts.

Japanese Numbers 1-10: How to Count to Ten in Japanese

The Japanese number system has two sets of numbers: the Sino-Japanese numbers and the Native Japanese numbers.

The most common Japanese numbers are the Sino-Japanese numbers. But you will often come across 1 – 10 in Native Japanese numbers.

10じゅう (juu)とう (tou)

Native Japanese Numbers

Let’s check out the Native Japanese row first. You’ll only see this system used up to 10, so that makes it easier.

The other cool bonus of this counting system: no counters!

I’ll cover counters in a moment, but this set of numbers is considered the universal counter. You can use it to count everything except money, time, and people. So, if you forget the right counter, use these numbers!

The tip to remembering these numbers is that they all end in つ (tsu) except for 10, which is とう (tou).

This also makes it easier when reading the kanji for these numbers. You can always tell which counting system is being used by whether the kanji is followed by つ or not (except 10).

Sino-Japanese Numbers

Now, let’s look at the Sino-Japanese numbers. These are the Japanese numbers you’ll use most often, and they combine with counters for counting objects.

Once you memorize these 10, counting to 100 is easy!

But take note: three numbers have two different readings: 4, 7, and 9.

The numbers 4 and 9 are considered unlucky in Japanese because し (shi) and く (ku) sound the same as the words for death (死, shi) and agony (苦, ku). So, Japanese people avoid using those readings whenever possible.

Even though 7 is a lucky number, it’s reading しち (shichi) also has し so it's more common to say なな (nana).

As for zero, the Japanese word is 零 (rei), but it's more common to say it like in English. ゼロ (zero) is most often used, or まる (maru) which means “circle” and is like saying “oh” in English instead of zero.

Japanese Numbers 1-100: How to Count to 100 in Japanese

Counting to 100 in Japanese is super easy once you learn the first 10, and it only uses one system! In Japanese, once you get past 10, you count as if you’re adding. Here’s how that looks:

11 is 十一 (juuichi): 10 + 1 12 is 十二 (juuni): 10 + 2

and so on up to 19.

Once you get to twenty, it’s the same concept, but you start by counting the 10s:

20 is 二十 (nijuu): 2 10’s 21 is 二十一 (nijuuichi): 2 10's + 1

and so on, up to 99.

100 gets a new word: 百 (hyaku).

Numbers in Japanese, 1 – 100: A Helpful Chart

A note about Japanese numbers: While counting Japanese numbers is straightforward, sometimes the readings change when used for things like dates and age.

For instance, 20 is called はたち (hatachi) when someone turns 20 years old because that is the age when one is considered to become an adult. Its other irregularity is はつか (hatsuka), which is the 20th day of the month.

Kanji Numbers in Japanese: 1 – 1 Trillion!

Japanese kanji make it easier to read numbers, as the Hiragana can get pretty long as you start getting to bigger numbers.

Plus, you don’t have to memorize too many of them, because of how the numbers are stacked to make bigger ones.

KanjiKana + Romaji
1いち (ichi)
2に (ni)
3さん (san)
4よん (yon)
5ご (go)
6ろく (roku)
7なな (nana)
8はち (hachi)
9きゅう (kyuu)
10じゅう (juu)
100ひゃく (hyaku)
1,000せん (sen)
10,000まん (man)
100,000十万じゅうまん (juuman)
1,000,000百万ひゃくまん (hyakuman)
10,000,000千万せんまん (senman)
100,000,000一億いちおく (ichioku)
1,000,000,000十億じゅうおく (juuoku)
1,000,000,000,000一兆いっちょう (icchou)

So, as you can see, the numbers continue to stack themselves all the way up past a trillion!

The biggest difference is that the big numbers are divided by units of 4 (or 10,000) rather than 3 (1,000). So once you get past 10,000, it can be a bit confusing to think of one million as “one hundred ten-thousands” at first.

How To Say Poker In Japanese

One note, though: Romanized numbers (1, 2, 3) are often used instead of kanji nowadays.

When those large numbers come up, they are written the same as in English. But, it's still important to learn the kanji because they *do still pop up, especially when paired with other kanji.

The Japanese Number System: The Most Common Japanese Counters

So we talked about them a bit earlier, but… What are Japanese counters?

Counters specify what kind of object you’re counting in Japanese. Japanese has many, many forms of counters for everything, from long objects to machinery.

It’s considered one of the most confusing points of learning Japanese. But, there are some tips to help you learn your way around it.

As I said earlier, if you don’t know the counter for an item, you can use the 一つ、二つ (hitotsu, futatsu) system to count your objects up to ten. This will save you a lot of trouble if you memorize the Native Japanese numbers!

The other thing to take note of is that some numbers conjugate differently with certain counters. The ones to look out for are 1, 3, 6, and 8.

Number 1 changes about half the time, while 3, 6, and 8 change most of the time.

三 (3) changes the first letter of any counter from the “h” column of the kana chart to “b” or “p,” like in 三分 (sanpun, “three minutes”).

六 (6) changes the “h” kana to “pp,” like 六匹 (roppiki, “six animals”).

八 (8) changes “h” counters the same as 6, usually. This is not quite a rule, but common enough to help you when you're getting started.

Sometimes, the less common readings of 4, 7, and 9 are used with certain counters, like 七時 (shichiji, “7 o’clock”).

Now that that’s out of the way, here are the most common counters you should know:

Japanese Counters for People

When counting people in Japanese, you use the counter ~人 (nin) for 3 or more people.

For one person, you say ひとり (hitori), and for two people you say ふたり (futari). Any number after that is the Sino-Japanese number system followed by ~人, such as 三人 (sannin, “three people”).

Japanese Counters for Long Objects

For long, thin objects, like pens, chopsticks, or bottles, the counter is ~本 (hon).

An example would be 四本のペン (yon hon no pen, “four pens”).

Although 本 means “book” in Japanese, it isn’t the counter for books (that’s ~冊, satsu, which is the counter for bound objects, like manga).

~本 is also the counter for things like roads, rivers, and train tracks – anything that travels that is very long and thin. It’s also used for long-distance telephone calls and travel routes.

Japanese Counters for Small Objects

Used for small objects, connect ~個 (ko) to the number to count it. And it’s also used for round objects, like apples: リンゴ二個 (ringo niko, ‘two apples”).

Japanese Counters for Animals

How To Say Poker In Japanese Characters

When counting small animals, you use ~匹 (hiki), like dogs and cats.

For larger animals, like horses or elephants, you use ~頭 (tou).

For example, 三匹の犬 (sanbiki no inu, “three dogs” – also note the change from h to b in hiki) and 三頭の馬 (santou no uma, “three horses”).

Japanese Counters for Mechanical Objects

Yes, even cars, your washer and dryer, and your video game console for playing games in Japanese have their own counter. Bicycles fall under this category, too.

You use ~台 (dai) for these objects, like 二台の車 (nidai no kuruma, “two cars”).

Japanese Counters for Units of Time

To express time in Japanese, you’ve guessed it, you use counters! You express seconds with ~秒 (byou), minutes with ~分 (fun or pun), hours with ~時 (ji), and length of time with ~時間 (jikan).

For months, you use ~月 (getsu), and for years you use ~年 (nen).

Other Common Japanese Counters

Other counters you’ll stumble across often are ~枚 (mai), ~回 (kai), and ~階 (kai or gai).

~枚 is used to count flat objects, like paper. ~回 is used to express the number of times, like the number of times in a week you workout. ~階 is used to count the number of floors in a building.

Japanese Grammar for Numbers

In Japanese, numbers can come before or after the item being counted.

But they typically come after the item + particle, such as はがきを五枚買います (Hagaki wo gomai kaimasu, “I will buy 5 postcards”). はがき (item counted) を (particle) 五枚 (number + counter) 買います (verb).

If you put the number before the item, then it needs の (no) to connect them.

Reversing the last sentence, 五枚のはがきを買います (Gomai no hagaki wo kaimasu) means the same thing but puts the emphasis on the quantity. It’s usually said this way in response to a question (like “How many did you buy?”).

A Final Note on Japanese Counters

Don’t feel too discouraged about counters in Japanese. They may seem strange or foreign, but we use them all the time in English too.

In English, we count lettuce, cabbage and garlic in heads, thin/fine objects like hairs and threads in strands, and pants in pairs. Some counters are unique to one noun, such as a skein of yarn.

If anything, Japanese is more logical than English when it comes to counters because there’s a counter for every noun instead of only a few select ones.

Japanese Ordinal Numbers

Japanese ordinal numbers express order or sequence, like first, second, and third.

In Japanese, you add 第~ (dai) before the number.

So first is 第一 (dai ichi)、第二 (dai ni), and so on.

For numbers with counters that you’re giving in a sequence, you add ~目 (me). So “for the first time” is 一回目 (ikkai me). “Third person” is 三人目 (sannin me).

Japanese Days of the Month

After counters, this is another difficult aspect of Japanese.

The days of the month are quite inconsistent, especially the first 10 days, plus the 14th, 20th, and 24th.

The first 10 days are more like the Native Japanese counting system, but… not quite. It’s best to just memorize them.

The days of the month in Japanese are:

1st – ついたち (tsuitachi) 2nd – ふつか (futsuka) 3rd – みっか (mikka) 4th – よっか (yokka) 5th – いつか (itsuka) 6th – むいか (muika) 7th – なのか (nanoka) 8th – ようか (youka) 9th – ここのか (kokonoka) 10th – とおか (tooka) 14th – じゅうよっか (juuyokka) 20th – はつか (hatsuka) 24th – にじゅうよっか (nijuuyokka)

The rest of the month follows the regular number stacking system + 日 (nichi), like 二十三日 (nijusan nichi, “23rd of the month”).

How to Say “Number” in Japanese + Some Math Words

To say “number” in Japanese, you can say 数 (kazu) to express a number as quantity, or 数字 (suuji) as in figures or cardinal numbers. “To count” is 数える (kazoeru).

If you need to express yourself in mathematical terms, here are some words you can use:

Plus: プラス (purasu) or 足す (tasu) Minus: マイナス (mainasu) Equals: は (wa) Multiply: 掛ける (kakeru) Divide: 割る (waru) Half: 半分 (hanbun) Point: 点 (ten)

Japanese Phone Numbers

Saying Japanese phone numbers out loud is pretty straightforward. You always read the numbers as single digits, then you say “の” (no) wherever the dash is.

So the number 123-456-7890 would be いち に さん の よん ご ろく の なな はち きゅう まる(ichi ni san no yon go roku no nana hachi kyuu maru).

Japanese Number Superstitions

Translator

The last thing you need to know for Japanese numbers? Superstitions! I already mentioned how 4 and 9 are considered to be unlucky numbers. Because they sound the same as “death” and “suffering,” you’ll notice throughout Japan that those numbers are missing. There may not be a 4th floor of a building, or room number 49.

Japanese Lucky Numbers

The number 7 is considered an extremely lucky number and this is deep-rooted in the culture. From national holidays like 七夕 (Tanabata, Evening of the 7th, on July 7th), to the celebration of life 7 days after birth, it pops up often.

The number 8 is also lucky because it’s said to bring prosperity. The kanji, 八, widens at the bottom to bring in more luck and success.

Introduction

Dai Fugō (大富豪 - 'very rich man'), which was formerly more often known as Dai Hinmin (大貧民 - 'very poor man') is a Japanese card game of the 'climbing' group. As in all these games, the aim is to get rid of all one's cards before the other players by playing them singly or in combination. It seems likely that the game was introduced from China in the 1970's. It became popular throughout Japan in the 1980's and 1990's, and during this time numerous additional rules and variations were introduced. It seems likely that some early version of Dai Hinmin was the direct ancestor of President, which became popular in the West a few years later. The basic game will be described first, followed by a selection of variants.

On this page, the 'o' with accent ('ō') is used to indicate a long 'o' sound in Japanese.

Players and Cards

Dai Fugō is usually played by from 3 to 6 players. A standard 52 card pack is used, to which one joker is normally added, so that there are 53 cards in all. The rank of the cards from high to low is:
Joker-2-A-K-Q-J-10-9-8-7-6-5-4-3.

Deal

Deal and play are clockwise. Any player may deal the first hand. After the first hand, the loser of each hand deals the next. All the cards are dealt out one at a time as equally as possible to the players. Some players will have one card more than others - this does not matter.

Play

In the first deal of a new session the first player is decided at random. As in many Japanese games, this is usually done by a game of Janken (similar to rock-paper-scissors). Each player chooses 'rock', 'paper' or 'scissors' and all choices are shown simultaneously by hand signals. If all three options are chosen at least once, or if everyone chooses the same option, it is a tie and the process is repeated. If just two of the three options are chosen, all players who picked the losing option (scissors beat paper, rock beats scissors, paper beats rock) are eliminated, and the process is repeated with only the survivors taking part. When there is only one survivor, this player starts the game.

The first player may play any card or valid combination, placing the card(s) face up in the centre of the table. The possible plays are:

Any single card.
Single cards rank as described above from 3 (low) to joker (high). A single card can only be beaten by a higher single card.
A pair.
Two cards of the same rank. A higher pair beats a lower pair: the lowest is 3-3 and the highest is 2-2.
Three of a kind (triplet).
Three cards of the same rank. A higher triplet beats a lower triplet: the highest is 2-2-2 and the lowest is 3-3-3.
Four of a kind.
Four cards of the same rank. In the basic game they rank in the same order as single cards, but note that many people now play that four of a kind causes a revolution - see variations.
A sequence
Three or more consecutive cards of the same suit, such as 4-5-6 or 9-10-J-Q. A sequence can only be beaten by a higher sequence containing the same number of cards. The highest 3-card sequence is K-A-2 and the lowest is 3-4-5. (A-2-3 and 2-3-4 are not valid sequences, since the 2 and 3 are not adjacent in this game.)

The joker may be used as a substitute for any card in a pair, triplet, four of a kind or sequence. A combination containing a joker is equal in rank to the equivalent combination made from natural cards. So for example the pairs 8-8 and 8-joker are equal: neither beats the other, and a sequence 9-10-Joker is equal in rank to 9-10-J.

After the first player has played a card or combination, each player in turn has the choice of passing (playing no cards) or playing a higher card or combination of the same type as the previous play. This continues as many times around the table as necessary until someone plays a card or combination which no one else is able or willing to beat. When all the other players has passed, the player of the unbeaten card or combination sets aside all the played cards face down, and begins again by leading any card or valid combination.

Here is an example with four players:

Player APlayer BPlayer CPlayer D
4-4pass7-78-8
passpassK-Kpass
passA-Jokerpasspass
pass

B's play is unbeaten, so she clears away the played cards and begins again with any card or valid combination. To beat B's A-Joker pair, a pair of twos would have been needed. Note that throughout this process only pairs could be played. For example at his first turn, player D would not be allowed to play three 8's or a single 2.

Please note that:

  • You do not have to beat the previous play just because you can - often it is better to pass and save your good cards for later.
  • Passing does not prevent you from playing at your next turn.

In the example, player B passed twice, although she could have played the A-Joker at her first or second turn, she decided to play only after C had used his Kings.

The objective is to get rid of all your cards. When a player runs out of cards, the play continues among the other players until only one player has cards left.

When a player plays his last card or cards, the other players as usual have the opportunity to beat this play. If no one beats it, since the player of the unbeaten card(s) has no more to play, the turn to begin again passes to the next player to the left who still has cards.

Result

If there are five or more players, the player who runs out of cards first is the Dai Fugō (very rich man), the second is the Fugō (rich man) the last player left with cards is the Dai Hinmin (very poor man) and the second last is the Hinmin (poor man). With three or four players, the winner, who runs out of cards first, is the Fugō and the loser, who is left with cards at the end, is the Hinmin.

As with many Japanese card games it is common to play without score or payment. The aim is simply to be as rich as possible as often as possible. If you prefer to formalise the result, the Dai Fugō should score +2 points, and the Fugō +1.

Exchange of cards

In the second and subsequent hands of a session there is an exchange of cards after the deal and before play begins. The Dai Hinmin must give his highest ranking two cards to the Dai Fugō and the Hinmin must give his highest card to the Fugō. In exchange, the Dai Fugō gives any two unwanted cards to the Dai Hinmin and the Fugō gives any one unwanted card to the Hinmin.

After the exchange, the loser of the previous hand (the Dai Hinmin, or the Hinmin if there are only three or four players) begins the play of the new hand with any card or valid combination.

Variations

More than six players
It is possible for as many as 8 players to take part. In Japan it is normal still to use a single deck of 53 cards, though in some Western adaptations, a larger number of players may use a double deck.
Revolution (kakumei)
Many people adopt the rule that any play of four of a kind (such as 9-9-9-9 or 5-5-5-Joker) causes a revolution, which reverses the ranking of the cards from the next time that the table is cleared. The joker remains the highest single card but the other cards rank from high to low 3-4-5-6-7-8-9-10-J-Q-K-A-2, so twos are now the lowest cards. If a second four of a kind is played, this causes a counter-revolution, which restores the original order. So if someone plays 5-5-5-5 to the empty table, another player can beat this with (for example) 7-7-7-7, and the card ranking order remains as it was, the revolution having been cancelled. But if everyone passes the 5-5-5-5 play, the cards are cleared and the revolution takes effect. If the player of the 5-5-5-5 now begins with (say) a pair of 6's, this can be beaten by 4-4 or 3-3 (the highest pair), but not by 8-8. The reversed order stays in effect until the end of the hand, unless another 4 of a kind is played, in which case there is a counter-revolution and the original order is restored. When the play ends, for the new deal the cards always revert to their original order.
Some people play that a revolution is also caused if anyone plays a five-card or longer sequence. Other variants are sometimes encountered, such as that a revolution is caused by a set of three 3's, or by a 4-card sequence. Some only allow a revolution with a genuine four of a kind, but not with three equal cards plus a joker.
Jokers
Rarely, this game is played without jokers, or with two jokers, in which case a pair of jokers is the highest pair. In an early form of the game, described to me in 1979, there were two jokers but no sequences were allowed. In the game with jokers, if the Dai Hinmin or the Hinmin was dealt both jokers there was a different kind of revolution, in which the roles of the players were reversed: the Dai Fugō became Dai Hinmin, Fugō became Hinmin and so on.
No twos in sequences
Some play that a 2 cannot be used to make a sequence K-A-2. In this version a sequence headed by an ace is unbeatable.
Miyako-Ochi
In this variant, if the Dai Fugō of the previous hand fails to win again and maintain his position, he automatically becomes Dai Hinmin. (Miyako can refer to Kyoto or any large and beautiful city, and ochiru is to fall, so the phrase Miyako-Ochi means exile from the city where the very rich man formerly lived.)
Suit lock rule (Shibari)
In this variant, if two consecutive plays are in the same suit, then subsequent players can only beat this with another play in the same suit. For example the 3 is played, this is beaten by a 4 which in turn is beaten by a 8. Subsequent players can only play clubs (or the joker), not other suits. This restriction applies until the table is cleared. A similar restriction applies if a sequence is beaten by a higher sequence in the same suit; this can then only be beaten by another sequence in that suit.
The suits are also locked if a pair is beaten by a higher pair in the same two suits - for example if 5-5 is beaten by 7-7, subsequent players can only beat this with a pair consisting of a spade and a diamond. A similar rules applies to triplets - the suits are locked if a triplet is beaten by a higher triplet using the same three suits.
Some also play with Kata-Shibari (partial suit lock). If a pair is beaten by a higher pair with one suit in common, then subsequent players can only beat this with a pair that includes the same suit. For example if 3-3 is beaten by 6-6, then this can only be beaten by a higher pair that includes a spade. If the next play is a spade-club pair, then that establishes a full lock and only spade-club pairs are allowed until the table is cleared. When triplets are played there can be a partial lock involving one or two suits.
Some play that suits are only locked if there are three consecutive plays in the same suit.
Cannot go out with highest card
Some play that you cannot go out by playing a 2 or a set of 2's as your last card(s). It's also illegal to go out by playing the highest sequence (K-A-2) or a single joker. If there has been a revolution (and no counter-revolution) then you cannot go out by playing a 3 or a set of 3's or a top sequence such as 3-4-5 or a single joker. When playing this variant, the penalty for going out with such an illegal play is that you automatically become the Dai Hinmin. Of course the penalty is rarely needed, since players avoid being left with cards that are illegal to play under this rule.
Some play that the penalty only applies to a player who goes out by playing a single joker.
Three of spades rule
Some play that when the joker is played as a single card, it can be beaten by the 3 of spades (but by no other card). The 3 can then in turn be beaten by any higher card. But if the 3 is played before the joker, the joker can beat it.
Eights rule (hachi-giri)
Some play that any 8 or combination containing an 8 causes the table to be cleared immediately. The person who played the 8 begins again by playing any card or valid combination.
When the hachi-giri rule is played, some also play that it is illegal to go out with a play that includes an eight.
Jack
A rarely played variation is that if a Jack is played, the ranking order of cards is immediately reversed, but this reversal lasts only until the cards are cleared. For example a 5 is beaten by a 9, which is beaten by a Jack. This reverses the ranking, so the Jack cannot be beaten by a Q, K, a or 2. It might, however be beaten by a 7, which in turn could be beaten by a 6 and then a 3. Then the cards would be cleared and ranking returns to normal.
Discard for tens
One correspondent reports a rule whereby anyone playing one or more tens is allowed to discard one further card from their hand for each ten played. These discards are placed face down in the pile of used cards.
Cannot play after passing
Another rarely played variant is that a player who passes is not allowed to play again until after the cards have been cleared.
Switching seats
Some people play that before each new deal the players change seats according to their result. The Dai Fugō sits to the right of the Dai Hinmin, then the Fugō and so on in order of their result, with the Hinmin to the Dai Hinmin's left.
According to some players, probably a minority, the positions are the reverse of this, with the the Dai Fugō to the left of the Dai Hinmin, followed by the Fugō and the other players in order: in this version Dai Fugō begins the play.
Card exchange variants
Some play that the loser must always exchange two cards with the winner, even if there are only 3 or 4 players, and with 4 players the second player exchanges one card with the third player.
Some play that if you are the Dai Hinmin and have the joker in your hand, you don't have to give it to the Dai Fugō
A few people play that the winners are allowed to ask for particular cards from the losers, and the losers must give these cards rather than their highest ranking cards, if they have them.
Scoring variants
Another possibility is that the Hinmin pays 1 point to the Fugō and the Dai Hinmin pays 2 points to the Dai Fugō.
