Meaning
触 means touch, contact, and physical sensation. It covers not just the literal act of touching something with your hand, but also emotional and metaphorical contact — being moved by someone's words, brushing up against a law, catching a disease through exposure.
触 is a compound ideograph (会意文字) built from 角 (horn) and 蜀 (a silkworm-like creature). Picture an insect probing its surroundings with horn-like antennae — reaching out, making contact, sensing everything it grazes. That image anchors the meaning well.
触 is a Jōyō kanji (常用漢字), grade 8, with 13 strokes. Its radical is 角 (つの, "horn"). Usage spans a wide range in everyday Japanese: 触る (to touch with your hand), 心に触れる (to be emotionally moved), 触媒 (catalyst, in chemistry), and 接触感染 (contact infection, in medicine).
Readings
On'yomi (音読み) — Chinese-derived readings
触 has one on'yomi: ショク (shoku). Derived from Middle Chinese, it appears mainly in compound words (熟語) — particularly in formal, scientific, and medical writing.
- 接触 (sesshoku) — contact, touch; used for physical contact, social interaction, and epidemiological exposure alike
- 感触 (kanshoku) — feel, tactile sensation; describes a surface's texture or the emotional impression something leaves
- 触媒 (shokubai) — catalyst; a chemistry term where 触 implies one substance making contact to drive a reaction
- 触覚 (shokkaku) — the sense of touch; one of the five senses (五感), referring specifically to tactile perception
- 触発 (shokuhatsu) — triggering, stimulation; one thing "touching" another to set off a chain reaction or emotional response
Kun'yomi (訓読み) — Native Japanese readings
触 has two kun'yomi: さわ(る) and ふ(れる). Both translate as "to touch," but they are not interchangeable.
さわる (sawaru) means touching something with the hand or fingers — direct, casual, often incidental. It can carry a slightly negative nuance: touching something you shouldn't, or engaging with something only on the surface.
- 触る (sawaru) — to touch, to feel with the hands
- 手触り (tezawari) — feel to the touch, the texture perceived with the hand
- 肌触り (hadazawari) — feel of something against the skin
ふれる (fureru) implies lighter, more delicate contact. Figuratively it means "to mention" something briefly, "to come across" something, or "to be exposed to" it. Emotional contact — being moved by a poem, stumbling onto a new idea — fits ふれる naturally. さわる does not work in those situations.
- 触れる (fureru) — to touch lightly, to come into contact with, to mention briefly
- 触れ合い (fureai) — warm interaction, connection between people
- 心に触れる (kokoro ni fureru) — to touch one's heart, to be emotionally moved

Memory Tip
触 is built from 角 (horn) and 蜀 (a silkworm-like creature). Think of a caterpillar using its tiny antennae to probe the world — reaching out, making contact, sensing everything it grazes. That image does the heavy lifting.
The two kun'yomi map to two kinds of contact. さわる is the caterpillar pressing its whole body against a leaf — direct, deliberate, hands-on. ふれる is just the tip of one antenna grazing the surface — barely touching, yet enough to sense something. Light contact, a brief mention, an emotional brush. Keep that gap between the two readings in mind.
