100 (one hundred) in Japanese is 百, read ひゃく (hyaku). Unlike English “one hundred,” the ordinary Japanese number does not add the word for “one” before hundred. You will use hyaku in prices, quantities, scores, and larger numbers. Adding the right unit or counter tells the listener what the hundred refers to.
Quick answer:
100 = 百 = ひゃく (hyaku). “One hundred yen” is 百円 (ひゃくえん, hyaku en), and “one hundred people” is 百人 (ひゃくにん, hyaku nin).
How Do You Say 100 in Japanese?
Say ひゃく (hyaku). The kanji is 百, and the familiar digit form is 100. Both can represent the same number in Japanese writing. The usual spoken form remains hyaku regardless of which representation you see.
Use: The number one hundred, alone when the unit is understood or before a suitable counter.
Do not build the ordinary number as ichi hyaku. Japanese simply uses hyaku for this amount. The word ichi is the number one, but it is not required before 百 in the normal counting expression for one hundred.
If the conversation already concerns a particular unit, the number may be enough as a short answer. In a full sentence, add the unit for clarity. Hyaku en names money, hyaku nin counts people, and hyakuten refers to one hundred points.
Writing and Using One Hundred
1. 百 — Kanji
百 represents hundred. It appears in larger numbers such as 二百, two hundred, and 百五十, one hundred and fifty. Learning the place value helps you read the whole number rather than treating each character as an unrelated vocabulary item.
Keep 百 separate from 千, thousand, and 万, ten thousand. A missing or mistaken place-value character changes the amount substantially. When learning a written number, practice saying its value aloud and checking that you have the intended unit.
2. ひゃく — Hiragana
The hiragana is ひゃく. Notice the small ゃ. The combination ひゃ is read hya, so the word is not a sequence of three separate full-sized sounds hi-ya-ku.
There is no small っ in hyaku. The number six hundred, roppyaku, and eight hundred, happyaku, have different consonant patterns, but the base hundred form does not contain that pause. Learn the kana of each form rather than copying a sound change everywhere.
3. 100 — Arabic Numerals
Digits are common in everyday Japanese text. You may see 100円, 100人, and 100ページ. These are read with the Japanese number and the following unit, not necessarily as separate English-style digits “one-zero-zero.”
If someone is reading a code or a string of digits, individual digit readings may be relevant. That is a different task from naming the numerical value one hundred. For a price or a quantity, start with the ordinary value reading hyaku.
4. 百円, 百人, and 百点 — Useful Units
百円 is ひゃくえん (hyaku en), one hundred yen. 百人 is ひゃくにん (hyaku nin), one hundred people. 百点 is ひゃくてん (hyakuten), one hundred points, such as a score in a suitable grading system.
These examples show why a unit matters. A bare “one hundred” can refer to many different quantities, while the unit makes the interpretation explicit. Japanese counters do not add an English plural -s after the number.

How to Pronounce Hyaku
Practice ひゃく as hya-ku. The first part moves smoothly from the initial consonant through a short y-like glide into the vowel. Do not turn it into a full separate “hee-yah” sequence. The final ku is short.
For English speakers, the initial sound can be unfamiliar because Japanese ひ is not always identical to a simple English h. Use the audio as your guide and aim for a compact, flowing first part. The romanization hyaku is a useful reminder, but it is not an exact English pronunciation spelling.
Practice the word inside a phrase such as ひゃくえんです, “It is one hundred yen.” The final vowel of ku may sound light in natural speech, but avoid adding a heavy English stress that stretches the number unnaturally.
Building Numbers After One Hundred
Japanese builds the following values from hundred, tens, and ones. You do not add a word corresponding to English “and.” For 125, say ひゃくにじゅうご (hyaku nijū go): hundred, twenty, five.
- 101 — 百一 — ひゃくいち (hyaku ichi)
- 105 — 百五 — ひゃくご (hyaku go)
- 110 — 百十 — ひゃくじゅう (hyaku jū)
- 120 — 百二十 — ひゃくにじゅう (hyaku nijū)
- 125 — 百二十五 — ひゃくにじゅうご (hyaku nijū go)
- 150 — 百五十 — ひゃくごじゅう (hyaku gojū)
- 199 — 百九十九 — ひゃくきゅうじゅうきゅう (hyaku kyūjū kyū)
For the hundreds, two hundred is にひゃく, three hundred is さんびゃく, and four hundred is よんひゃく. The hundred part changes its sound in some combinations. In particular, three hundred has byaku, while six hundred and eight hundred use forms ending in ppyaku.
Learn these as established number readings rather than inventing a pronunciation from English arithmetic. The written place-value structure remains clear even when the spoken consonant changes.
Choosing the Right Counter
Japanese uses counters for many kinds of objects. 枚 (まい) is useful for flat items such as sheets, while 冊 (さつ) counts books and other bound volumes. 人 (にん) counts people in the expression 百人.
The noun and number phrase can appear in different sentence positions. Hyaku nin no gakusei means “one hundred students,” while Gakusei ga hyaku nin imasu means “There are one hundred students.” Both contain the same number and counter, arranged in a different structure.
Some counters introduce additional pronunciation changes after certain numbers. Start with a few useful combinations and learn them as a whole. Hyaku en, hyaku nin, hyaku mai, and hyaku satsu are a practical set for prices, people, flat items, and books.
Example Sentences
Each example includes the ordinary written sentence and a kana reading. The audio follows the kana to make the intended number pronunciation clear.
This pencil is one hundred yen.
Use: 円 gives the currency unit. The phrase hyaku en names the amount.
There are one hundred students.
Use: 人 counts people, and います describes their presence.
This book has one hundred pages.
Use: ページ counts pages. The same number hyaku appears before the unit.
Common Mistakes
Do not add ichi to the ordinary number one hundred. Use hyaku, not ichi hyaku. Keep the ゃ small in ひゃく, and avoid inserting an extra full syllable between h and ya.
Do not read every written 100 as three separate digits when the context is a normal quantity. Also avoid adding an equivalent of “and” inside 125 or 150. Finally, include a suitable unit when the amount would otherwise be ambiguous, and learn the counter that matches the thing being counted.
