Numbers are necessary in everyday life as you need them to express time, record dates, interpret recipe amounts, count objects, and the list goes on. Japanese numerical systems have unique features and they are very different from those in English.

For example, Japanese has a variety of counter words depending on different factors. Further, large numbers are counted by units of four digits while the Western system counts by that of three digits, and the differences only continue for numbers in the Japanese language.

1. Counting in Japanese: Numbers 0-9

These are the basic Japanese numbers for 0 to 10. You absolutely need to know these numbers in learning Japanese so that you can use them to build bigger numbers.

The standard way of reading 0 to 10 is also used in combination with counter words when you count anything, including actions and events. The Arabic numerals (0, 1, 2, 3…) are also commonly used in Japanese, but they often appear in horizontal texts, while the numbers in Kanji are mostly used in vertical texts, especially in formal writings and in particular situations.

As it’s written in the chart, there are some numbers which can be read two ways:

• 0 can be ぜろ(Zero) or れい (Rei). Nowadays, “Zero” is more common to read, and the Kanji 零 is rarely used.
• 4 can either be し(Shi) or よん (Yon).
• 7 can either be しち(Shichi) or なな (Nana).
• 9 can be either く(Ku) or きゅう (Kyū).

In most circumstances, both are acceptable. In general, よん (Yon), なな (Nana), and きゅう(Kyū) sound more casual and common.し(Shi), しち (Shichi), and く(Ku) sound more formal.

2. Counting in Japanese: Numbers 10-99

You can count from 1 to 99 with just ten numbers (0-10). Japanese numbers are simple and easier to use than English in this respect because there’s no exception or particular separate words such as “twenty” or “thirty.” In Japanese, these are expressed “two ten” and “three ten.” 21 is “two ten one.”

The Arabic numerals are commonly used and Kanji is also used in some circumstances. However, Hiragana isn’t used to express numbers. Like the cases of idiomatic words or a combination of Kanji (熟語 じゅくご Jukugo), Hiragana can become long to express and hard to decipher.

For more on Japanese numbers, YouTube has some great content. Please visit our JapanesePod101 YouTube channel and watch Learn Japanese Numbers 1 to 20 to learn Japanese basic numbers. You can listen to hear how they’re actually pronounced.

3. Counting in Japanese: Numbers up to 1000

From 100 to 1000, the pattern is basically simple and the same. In Japanese, as you can see in the chart, you can simply put the numbers 1 to 9 and add 100 to express 100 to 900 in Japanese. There are some exceptions for reading, such as 300, 600, and 800.

• 100 is hyaku, but 300 is read san (3) Byaku (100)
• 600 is roppyaku instead of “roku hyaku,”
• 800 is happyaku instead of hachi hyaku.
• 3000 is san (3) zen (100)
• 8000 is hassen instead of hachi sen

4. Counting in Japanese: More than 10,000

For the large numbers, Japanese numerals are divided into units of four (as in the four zeros in ten thousand). As you can see in the chart, 万 (man) is 10^4, 億 (oku) is 10^8, and 兆 (chō) is 10^12. One million is expressed as one hundred ten-thousands or 百万 (hyaku-man) in Japanese.

Note that you don’t need to put a 1 for 百 (hyaku) meaning 100 or 千 (sen) meaning 1000. But for units past 1000, you need to put a 1 in front. For example:

• 万 ichi-man ( 10^4 )
• 億 ichi-oku ( 10^8 )
• 兆 ichhō ( 10^12 )

You also read numbers in Japanese in the same pattern as mentioned before. You can count by simply chaining the numbers. However, there’s also an exception for the large numbers: 10^12 is 兆 ichhō instead of ichi-chō.

For the large numbers, the Arabic numerals are used in combination with Kanji, such as in 5万 (go-man), 4千万 (Yon-sen-man), 100億 (hyaku-oku), 3兆 (san-chō), etc.

5. Decimal Fraction / Fraction Numbers in Japanese

1- Decimal Fractions

0 before the decimal point is read rei and 0 after the point can be either rei or zero. The decimal point is called ten which literally means “point.”

2- Fraction Numbers

For fraction numbers in Japanese, the number after / is read first. / is expressed as 分の (bun no).

6. How to Say Prices in Japanese

The Japanese currency is Yen and it’s read en. Expressing prices is very simple: you just use the numbers and en. The Arabic numerals are usually used for prices.

7. Shopping Using Numbers in Japanese

The phrase いくら (ikura) which means “How much” is often used in shopping.

The word “Price” is 値段 ねだん (nedan) in Japanese.

Examples for Shopping:

• A: このりんごの値段はいくらですか。
  A: Kono ringo no nedan wa ikura desu ka.
  A: How much is the price for this apple?
