用 — Use, Task, Business

Meaning

The kanji 用 (yō) is a versatile character found everywhere in Japan, from snack labels to subway signs. It primarily means 'use,' 'service,' or 'business/task.' At the JLPT N4 level, this character is fundamental because it forms the core of many daily expressions. Whether you are running an errand or describing the utility of a tool, 用 is the essential character to know.

Originally, this kanji was an ideograph depicting a wooden bucket or a specialized tool. Some scholars suggest it represented a fence used for divination, but the modern focus remains on practical utility. Structurally, it consists of 5 strokes and acts as its own radical, though some dictionaries group it under the 冂 (box) radical. It is taught in the 2nd grade of Japanese elementary school, highlighting its importance in basic literacy.

Readings

Mastering the readings of 用 allows you to distinguish between formal verbs and common noun compounds.

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

The most frequent reading is ヨウ (yō). It appears in most kanji compounds (jukugo) and often implies a formal or abstract sense of 'utilization' or 'task.' Ensure you hold the long 'o' sound for proper pronunciation.

• 用事ようじ (yōji) — Errand, business, things to do
• 用意ようい (yōi) — Preparation, arrangements
• 利用りよう (riyō) — Use, utilization (especially of facilities or systems)

Kun'yomi (訓読み) — Native Japanese readings

The native Japanese reading is もち.いる (mochi.iru). While the verb 使つかう (tsukau) is common for general 'using,' 用もちいる is more formal. It is frequently found in written Japanese, academic texts, or when discussing the adoption of a specific method.

• 用もちいる (mochiiru) — To use, to adopt (a method), to employ
• 用もちい方かた (mochiikata) — Usage, way of using

Memory Tip

Think of 用 as a traditional Japanese tool box. The outer box (strokes 1, 2, and 5) holds everything together, while the internal grid (strokes 3 and 4) organizes the tools inside. A well-organized box makes the tools 'useful' for any task. Alternatively, imagine a fence with a gate; once you open the gate, you can enter to do your 'business' or 'errands.'
