Number Romaji Hiragana/Katakana
0 zero (rei) ゼロ (れい)
1 ichi いち
2 ni に
3 san さん
4 yon (shi) よん (し)
5 go ご
6 roku ろく
7 nana (shichi) なな (しち)
8 hachi はち
9 kyuu (ku) きゅう (く)
10 juu じゅう
Number Romaji Hiragana/Katakana Numbers 11-20 is very easy!
11 juuichi じゅういち It is just a pattern from the first set of
12 juuni じゅうに cardinal numbers 1-10.
13 juusan じゅうさん 11 is a combination of 10 and 1
juu and ichi, that makes it juuichi
14 juuyon じゅうよん
15 juugo じゅうご 12 is a combination of 10 and 2
juu and ni, that makes it juuni
16 juuroku じゅうろく
17 juunana じゅうなな 20 is like 2 number 10
or mathematically speaking
18 juuhachi じゅうはち 2 x 10 = 20
19 juukyuu じゅうきゅう ni x juu = nijuu
20 nijuu にじゅう
Number Romaji Hiragana/Katakana Just like how number 20 is formed,
the same pattern goes with the rest of the
10 juu じゅう tens.
20 nijuu にじゅう
30 is like 3 number 10
30 sanjuu さんじゅう or mathematically speaking
40 yonjuu よんじゅう 3 x 10 = 30
san x juu = sanjuu
50 gojuu ごじゅう
40 = 4 x 10
60 rokujuu ろくじゅう
yon x juu = yonjuu
70 nanajuu ななじゅう
So when we say 48
80 hachijuu はちじゅう the pattern is yon x juu + hachi = yonjuuhachi
90 kyuujuu きゅうじゅう
100 or hyaku is another set of numbers
100 hyaku ひゃく denoting hundreds
Number Romaji Hiragana/Katakana As you can see at the left side, there
are letters indicated in red text.
100 hyaku ひゃく
200 nihyaku にひゃく Although hundreds also follow the
format like
300 sanbyaku さんびゃく 200 = 2 x 100
ni x hyaku = nihyaku
400 yonhyaku よんひゃく
500 gohyaku ごひゃく However, numbers 300, 600 and 800
are spelled and pronounced differently
600 roppyaku ろっぴゃく unlike the rest of the hundreds.
700 nanahyaku ななひゃく
Learners are advised to just simply
800 happyaku はっぴゃく memorize the special numbers rather
than analyzing it.
900 kyuuhyaku きゅうひゃく
1,000 sen せん
How to properly form 3 digit patterns
Example:
106 = 100 + 6
hyaku + roku = hyakuroku
220 = (2 x 100) + (2 x 10)
nihyaku + nijuu = nihyakunijuu
338 = (3 x 100) + (3 x 10) + 8
sanbyaku + sanjuu + hachi = sanbyakusanjuuhachi
874 = (8 x 100) + (7 x 10) + 4
happyaku + nanajuu + yon = happyakunanajuuyon
Number Romaji Hiragana/Katakana Special numbers are also present in the
thousands group.
1,000 sen せん
2,000 nisen にせん 3,000 is pronounced as sanzen
and 8,000 as hassen.
3,000 sanzen さんぜん
10,000 is completely pronounced as
4,000 yonsen よんせん
ichiman, unlike in 100 which hyaku and
5,000 gosen ごせん 1,000 which is sen only.
6,000 rokusen ろくせん
7,000 nanasen ななせん
8,000 hassen はっせん
9,000 kyuusen きゅうせん
10,000 ichiman せん
Number Romaji Hiragana/Katakana Here are examples of larger numbers.
11,001 ichimanissenichi いちまんいっせんいち When 1,000 appears in higher units,
20,000 niman にまん you read it [issen (ichi + sen)]
100,000 juuman じゅうまん For example:
1 million hyakuman ひゃくまん 21,000 is [ ni man issen]
10,000 is [issen man]
10 million issenman いっせんまん 100 million is [ichi oku], not just [oku]
100 million ichioku いちおく 1 trillion is [icchoo (ichi + choo)], not
just [choo]
1 billion juuoku じゅうおく
10 billion hyakuoku ひゃくおく However, discussion on patterns for
larger numbers are discussed in
100 billion issenoku いっせんおく Nihongo 2.
1 trillion icchoo いっちょう
10 trillion jucchoo じゅっちょう
Techniques on higher numbers
• To easily say numbers involving several digits, say in millions, billions,
and trillions.
• Here is a technique to easily remember them.
• Larger numbers beginning 5 digits and up can be grouped in this
manner:
Example: (5 digits) - man
• Example: 11,001 ichimanissenichi
• Step 1: Group the digits by four.
1 | 1001
• Step 2: Count the number in each group based on the basic 1 to 1,000
counting.
The first group (starting from the right) is the sen (thousands),
the second group is the man.
Example: (5 digits) - man
• So we say,
man sen
1 | 1001
ichi man | issen ichi
11,001 = ichimanissenichi
Example: (5 digits) - man
• Another example: 20,000
man sen
2 | 0000
ni man | -
20,000 = niman
Example: (6 digits) - man
• Another example: 100,000
man sen
10 | 0000
juu man | -
100,000 = juuman
Example: (7 digits) - man
• Another example: 1,000,000
man sen
100 | 0000
hyaku man | -
1,000,000 = hyakuman
Example: (8 digits) - man
• Another example: 10,000,000
man sen
1000 | 0000
issen man | -
10,000,000 = issenman
Example: (9 digits) - oku
• Another example: 100,000,000
oku man sen
1 | 0000 | 0000
ichi oku | - |-
10,000,000 = ichioku
Example: (9 digits) - oku
• Another example: 123,000,000
oku man sen
1 | 2300 | 0000
ichi oku | - nisen sanbyaku man | -
123,000,000 = ichiokunisenbyakuman
Example: (9 digits) - oku
• Another example: 123,045,876
oku man sen
1 | 2304 | 5876
ichi oku | - nisen sanbyaku yon man | - go sen happyaku nanajuuroku
123,045,876 =
ichiokunisensanbyakuyonmangosenhappyakunanajuuroku
