Mastering Japanese Kanji: When to Use Onyomi vs Kunyomi for Fluent Reading

Mastering Japanese Kanji is one of the most rewarding steps in achieving fluency in Japanese, but it can be challenging due to Kanji's multiple readings: Onyomi and Kunyomi. In this guide, you’ll learn the fundamentals of when to use each reading, making Japanese reading less of a mystery.

Unlocking Kanji Secrets: When to Use Onyomi vs Kunyomi

Onyomi and Kunyomi are the two main ways of reading Kanji characters. Onyomi is based on the original Chinese pronunciation and is commonly used in Kanji compounds, while Kunyomi is the Japanese reading, often applied when Kanji appear alone or with Hiragana characters. These distinctions are crucial for understanding Japanese grammar and building vocabulary.

How to Decide: Onyomi vs Kunyomi for Every Kanji

Deciding which reading to use can be simplified with a few general guidelines.

1. Kanji Compound Words (Onyomi likely)

In Kanji compounds, where two or more Kanji form a single word, Onyomi is often used. For example, in 大学 (Daigaku, "university"), both Kanji 大 (big) and 学 (study) use Onyomi.

2. Okurigana (Kunyomi likely)

When Kanji are followed by Hiragana to complete the reading, as in Japanese adjectives or verbs, Kunyomi is usually applied. For example, 楽しい (Tanoshi, "fun") combines the Kanji 楽 (fun, comfort) with Hiragana しい.

3. Single Kanji Character (Kunyomi likely)

When a Kanji appears alone, especially in everyday contexts, Kunyomi is generally used. For instance, 山 (Yama, "mountain") uses the Kunyomi reading.

Names of Japanese People and Places (Kunyomi likely)

In personal names and place names, Kunyomi is typically used, as with the name 山田 (Yamada, "Mr. Yamada"), where 山 is read as "Yama."
