Japanese Numbers at a Glance

🔢 Two Number Systems

Native Japanese numbers (いち, に, さん) and Sino-Japanese numbers (一, 二, 三) serve different purposes in daily conversation.

📝 Essential for Daily Life

Counting is fundamental to Japanese. You need number kanji for prices, dates, times, phone numbers, and addresses.

Two Counting Systems Explained

Japanese has two distinct number systems, and knowing when to use each is essential for fluency.

Sino-Japanese Numbers (音読み)

Borrowed from Chinese, used for:

  • •Telling time (いちじ = 1 o'clock)
  • •Counting money (ひゃくえん = 100 yen)
  • •Phone numbers and addresses
  • •Math and arithmetic
  • •Dates and years (にせんにじゅうご = 2025)
  • •Most counter words attach to Sino-Japanese numbers

いち (1), に (2), さん (3), し/よん (4), ご (5), ろく (6), しち/なな (7), はち (8), きゅう/く (9), じゅう (10)

Native Japanese Numbers (訓読み)

Traditional Japanese counting, used for:

  • •Counting objects without a counter (up to 10)
  • •Ages of young children
  • •How many people in casual speech
  • •Traditional Japanese counting
  • •Some counter expressions (一つ, 二つ…)
  • •Only goes up to 10; after that, use Sino-Japanese

ひとつ (1), ふたつ (2), みっつ (3), よっつ (4), いつつ (5), むっつ (6), ななつ (7), やっつ (8), ここのつ (9), とお (10)

Japanese Counter Words (助数詞)

In Japanese, counting objects requires special "counter" words that attach to numbers. The counter changes depending on the type of object.

個
〜こ (ko)
Small round objects

りんご三個 (3 apples), たまご六個 (6 eggs)

本
〜ほん/ぼん/ぽん (hon)
Long thin objects

えんぴつ二本 (2 pencils), びん三本 (3 bottles)

枚
〜まい (mai)
Flat thin objects

かみ一枚 (1 sheet of paper), シャツ五枚 (5 shirts)

冊
〜さつ (satsu)
Bound books

ほん三冊 (3 books), ざっし二冊 (2 magazines)

匹
〜ひき (hiki)
Small animals

いぬ二匹 (2 dogs), ねこ四匹 (4 cats)

台
〜だい (dai)
Machines, vehicles

くるま一台 (1 car), パソコン三台 (3 computers)

杯
〜はい/ばい/ぱい (hai)
Cups, glasses, bowls

みず一杯 (1 glass of water), コーヒー二杯 (2 coffees)

人
〜にん/り (nin/ri)
People

ひとり (1 person), ふたり (2 people), さんにん (3 people)

How to Read Large Numbers in Japanese

Japanese groups numbers in units of 10,000 (万, まん) rather than 1,000 like English. This can be confusing at first!

15十五じゅうご (juu-go)10 + 5
24二十四にじゅうし (ni-juu-shi)2×10 + 4
100百ひゃく (hyaku)One hundred
365三百六十五さんびゃくろくじゅうご3×100 + 6×10 + 5
1,000千せん (sen)One thousand
2,025二千二十五にせんにじゅうご2×1000 + 2×10 + 5
10,000一万いちまん (ichi-man)Japanese groups by 10,000 (万), not 1,000
100,000十万じゅうまん (juu-man)10 × 10,000 (not "one hundred thousand")

Tips for Memorizing Number Kanji

✏️

Write Them Repeatedly

Number kanji have simple stroke patterns. Write each one 10 times to build muscle memory. 一 is one horizontal stroke, 二 is two, 三 is three. Very logical!

🛒

Practice with Real Prices

Japanese prices are great practice. A convenience store receipt like "¥1,480" becomes 千四百八十円. Reading prices trains your brain to parse large numbers fast.

📅

Learn Dates Early

Japanese dates use number kanji directly: 二〇二五年一月二十日 (January 20th, 2025). Learning the date format gives you instant daily practice.

🎮

Use Spaced Repetition

Our free quiz app uses spaced repetition to show you number kanji at exactly the right time for maximum retention. Spend 5 minutes a day reviewing.

🔄

Master Both Readings

Don't just learn いち, に, さん. Study ひとつ, ふたつ, みっつ too. Native Japanese numbers are used in casual speech and essential for true fluency.

🧮

Practice Mental Math in Japanese

Try doing simple arithmetic (5+3, 12×2) using Japanese readings in your head. This builds automatic number recognition that feels natural.
