Numbers
The numbers in Japanese both are written in kanji or arabic numerals. Kanji are the traditional Japanese way to write them, however it is very common to use arabic numbers. Some Japanese numbers have more than one way of saying them.
Number  Japanese  Romaji  0  ゼロ/零 (れい)  zero/rei  1  一 (いち)  ichi  2  二 (に)  ni  3  三 (さん)  san  4  四 (し/よん)  shi/yon  5  五 (ご)  go  6  六 (ろく)  roku  7  七 (なな/しち)  nana/shichi  8  八 (はち)  hachi  9  九 (きゅう/く)  kyuu/ku  10  十 (じゅう)  juu 
Which pronunciation of the number you are using, depends on what you are talking about. When you are counting for 9 you use kyuu. When you count to 10 you can use both words for 7 and 4, but after ten you use yon and nana to count.
After 10
In Japanese there numbers past ten do not use different words. Instead they follow the pattern ten + one, ten + two. To say 11, you take 10 (juu) + 1 (ichi) after it. The pattern continues.
Number  Japanese  Romaji  11  十一 (じゅういち)  juu ichi  14  十四 (じゅうよん)  juu yon  18  十八 (じゅうはち)  juu hachi  16  十六 (じゅうろく)  juu roku 
When you get to 20 you add 2 (ni) in front of 10 (juu). In English this is equal to saying two ten. This pattern is the same for 30, 40 and so on.
Number  Japanese  Romaji  20  二十 (にじゅう)  ni juu  30  三十 (さんじゅう)  san juu  40  四十 (よんじゅう)  yon juu  50  五十 (ごじゅう)  go juu 
To say numbers between 2129 you follow the same pattern and add the number after juu like you did number 1119.
Number  Japanese  Romaji  21  二十一 (にじゅういち)  ni juu ichi  27  二十七 (にじゅうなな)  ni juu nana  23  二十三 (にじゅうさん)  ni juu san  29  二十九 (にじゅうきゅう)  ni juu kyuu 
This pattern continues all the way up to 99.
Number  Japanese  Romaji  35  三十五 (さんじゅうご)  san juu go  24  二十四 (にじゅうよん)  ni juu yon  66  六十六 (ろくじゅうろく)  roku juu roku  89  二十九 (はちじゅうきゅう)  hachi juu kyuu 
100+
The word for hundred is hyaku. The same pattern applies to all numbers 100199.
Number  Japanese  Romaji  101  百一 (ひゃくいち)  hyaku ichi  167  百六十七 (ひゃくろくじゅうなな)  hyaku rokujuu nana  115  百十五 (ひゃくじゅうご)  hyaku juu go  182  百八十二 (ひゃくはちじゅうに)  hyaku hachijuu ni 
When you get to 200, you need to add two in front of hundred.
Number  Japanese  Romaji  208  二百八 (にひゃくはち)  nihyaku hachi  290  二百九十 (にひゃくきゅうじゅう)  nihyaku kyuu juu  241  二百四十一 (にひゃくよんじゅういち)  nihyaku yonjuu ichi 
This pattern continues the same for most numbers but there are some differences in pronunciation. The numbers below don't follow the usual pattern so you have to memorize them.
300 becomes sanbyaku (さんびゃく)
600 becomes roppyaku (ろっぴゃく)
800 becomes happyaku (はっぴゃく)
1000+
When you get to 1000 you use the word sen which means thousand. You follow same pattern as before.
Number  Japanese  Romaji  1200  千二百 (せんにひゃく)  sen nihyaku  1602  千六百二 (せんろっぴゃくに)  sen roppyaku ni  1460  千四百六十 (せんよんひゃくろくじゅう)  sen yonhyaku rokujuu 
There are only two odd rules with numbers in the 1000's.
3000 becomes sanzen (さんぜん)
8000 becomes hassen (はっせん)
When saying 10,000 you use the counter man which is ten thousand. However the is something different. For 10,000 you must say ichi before man. This pattern continues.
Number  Japanese  Romaji  17000  一万七千 (いちまんななせん)  ichiman nanasen  28500  二万八千五百 (にまんはっせんごひゃく)  niman hassen gohyaku 
We will learn to count higher in future lessons. Don't worry so much if you can't remember all these numbers, we will review numbers a lot in our lessons.
