良 — Good, Excellent, Virtuous

Meaning

The kanji 良 (ryō, yoi, ii) broadly means 'good' in Japanese. It covers various positive attributes like 'excellent,' 'virtuous,' 'skilled,' 'fine,' and 'pleasing.' You'll find this character describing quality, character, and suitability across many situations, indicating something inherently positive.

Many believe 良 originated from an ancient pictograph. Earlier forms showed a person (possibly with a 人-like component) wearing something beautiful or auspicious, or perhaps facing a direction that implied uprightness. Another theory suggests it depicted someone of good standing, identifiable by a special head covering. While the modern form has simplified, its core radical is 艮 (こん, ねづくり), which itself can mean 'stop' or 'good.' This radical helps convey stability and inherent value. This underlying sense of positive quality has remained consistent through the character's evolution.

Even in its modern form, 良 suggests balance and uprightness, even if it's no longer a clear pictograph. The strokes at the top can be seen as an enclosure or a crown, while the lower part forms a solid base. Together, they create a well-founded, positive image, aligning with the idea of 'goodness' or 'correctness.'

With 7 strokes, 良 is a foundational kanji taught in the 4th grade of Japanese elementary school. For JLPT learners, it's an N2 level kanji, commonly appearing in intermediate vocabulary.

Readings

On'yomi (音読み) — Chinese-derived readings

The primary On'yomi (Chinese-derived reading) for 良 is リョウ (RYŌ). You'll hear this reading in compound words, especially nouns, where 良 means 'good,' 'excellent,' or 'satisfactory.' It's highly prevalent in formal, academic, and compound words describing quality, condition, or moral attributes. When 良 appears at the beginning or middle of a compound word, リョウ is almost always the correct reading.

• 良好りょうこう (ryōkō) — good, favorable, satisfactory (e.g., a good condition)

• 優良ゆうりょう (yūryō) — superior, excellent, good quality (e.g., an excellent company)

• 善良ぜんりょう (zenryō) — good, virtuous, benevolent (e.g., a virtuous person)

• 良心りょうしん (ryōshin) — conscience (e.g., having a good heart)

• 改良かいりょう (kairyō) — improvement, reform

Kun'yomi (訓読み) — Native Japanese readings

For native Japanese readings (Kun'yomi), 良 primarily takes the adjective forms よい (yo.i) and いい (ii). Both mean 'good,' 'nice,' 'fine,' or 'pleasant.' 良いよい is the dictionary form, serving as the base for conjugations like 良くないよくない ('not good') and 良かったよかった ('was good'). In contrast, 良いいい is the more common colloquial form for present tense affirmative sentences, often seen as a contraction of 良いよい. These readings are indispensable for expressing positive qualities in daily Japanese.

• 良いよい (yoi) — good, fine, excellent (dictionary form, used for formal statements and conjugations)

• 良いいい (ii) — good, fine, excellent (colloquial form, commonly used in everyday speech)

• 良かれよかれ (yokare) — for good (an archaic or literary expression, often seen in the fixed phrase 良かれよかれと思おもって - thinking it was for the best)

• 良くよく (yoku) — well, often (adverbial form of 良いよい)

Example Sentences

Memory Tip

To remember 良, imagine a person who is 'good' and 'upright.' You can see the top part as a head with a positive aura or halo, symbolizing goodness. The bottom part, 艮 (ねづくり), is itself a radical meaning 'good' or 'upright,' further cementing the primary meaning. Another way to visualize it is a person standing with a sturdy, balanced stance, representing stability and inherent positive quality. This balanced shape reinforces the idea of something fundamentally good and correct. Here's a quick story: 'A good person always stands upright and balanced.'
