On'yomi vs Kun'yomi: A Beginner Guide with JLPT N5 Examples
Understand on'yomi and kun'yomi through common N5 words, practical reading patterns, and examples from a Japanese teacher.
Why can one kanji have several readings? The short answer is that Japanese kept native Japanese words and also adopted pronunciations connected to Chinese. These became the two reading families learners call kun'yomi and on'yomi.
You do not need to guess perfectly or memorize a long reading chart. The useful skill is recognizing common word patterns and learning each reading inside vocabulary.
What is kun'yomi?
Kun'yomi is a native Japanese reading attached to a kanji meaning. A single kanji used as a word often takes a kun reading: 山（やま, mountain） and 人（ひと, person）. Verbs and adjectives with hiragana endings also commonly use kun readings: 食べる（たべる）, 見る（みる）, and 大きい（おおきい）.
What is on'yomi?
On'yomi is a reading associated with pronunciations brought from Chinese at different periods. Kanji compounds often use on readings: 学生（がくせい）, 時間（じかん）, and 日本人（にほんじん）.
The practical beginner pattern
One kanji standing alone or followed by hiragana: kun'yomi is common.
Two or more kanji joined together: on'yomi is common.
This is a helpful starting pattern, not a rule without exceptions. Words such as 手紙（てがみ） use kun readings in a compound, while 本（ほん） is a single kanji word using an on reading.

Why memorizing every reading first does not work
A kanji dictionary can show many readings, but only a few may be useful at N5. If you memorize an isolated list, you still will not know which pronunciation belongs in a sentence.
Instead, learn a small set of words. For 生, a beginner might first learn 学生（がくせい）, 先生（せんせい）, and 生まれる（うまれる）. The vocabulary gives each reading a job.
A four-step way to learn readings
1. Meaning: recognize the main idea of the kanji.
2. One common word: learn the kanji inside a word you can use.
3. One contrasting reading: add a second word only after the first feels familiar.
4. Sentence: read both words in short, natural sentences.
Example: 山
Start with 山（やま）: 山に登ります。 Then add 富士山（ふじさん）: 富士山を見ました。 Later, 火山（かざん） introduces another sound change without forcing you to memorize every possibility on day one.
Practice readings and writing together
The workbook places meaning, on and kun readings, stroke order, four vocabulary words, and an example sentence together. This keeps the character, sound, and usage connected.
Writing a character in a fixed order also makes its parts easier to recognise — see Japanese kanji stroke order: 7 rules for beginners.

Frequently asked questions
Do compounds always use on'yomi?
No. It is a useful pattern, but Japanese has many mixed and native-reading compounds. Learn the pronunciation with the whole word.
Which reading should I write on a flashcard?
Write one useful word on the front or back instead of listing every reading. Add another word when you meet it in your lessons.
