Meaning
Today, we're exploring the N1 kanji 侵. This character conveys a sense of forceful or unwelcome entry. The kanji 侵 fundamentally means to invade, encroach, trespass, or violate. It implies crossing a boundary—whether physical, legal, or personal—often without permission or with hostile intent. This could manifest as a gradual, subtle encroachment or a direct, aggressive invasion.
To understand its meaning more deeply, we will examine its visual structure and origin. The kanji 侵 is a phono-semantic compound, combining a radical that suggests its general meaning with a component that hints at its sound. On the left, we find the radical 亻, the "person" radical, commonly seen in kanji related to people or human actions.
The right side features 寖, a variant of 浸. This component provides the phonetic hint "shin" and originally depicted a person sleeping deeply or water soaking in slowly. Combining the "person" radical with this sense of "deeply into" or "gradual soaking" powerfully evokes the image of an entity slowly yet surely moving into an unwelcome space. This represents encroachment or invasion. Imagine someone subtly creeping into an area, or water gradually permeating a surface. This gradual, often unwelcome, penetration or violation is central to the kanji's meaning.
Comprising 9 strokes, 侵 is an N1 level kanji. This means it is considered advanced and typically encountered by learners aiming for fluency in Japanese, as it is not part of the common Jōyō Kanji taught in elementary or junior high school.
Readings
Like many Japanese kanji, 侵 has two primary types of readings: On'yomi (Chinese-derived) and Kun'yomi (native Japanese).
On'yomi (音読み) — Chinese-derived readings
The primary On'yomi for 侵 is シン (shin). This reading is almost exclusively used within compound words, often paired with other kanji of Chinese origin. You'll frequently encounter it in formal, academic, or news contexts, particularly when discussing national security, legal violations, or bodily harm.
- 侵略 (shinryaku) — invasion; aggression. This is a key term, particularly in historical or geopolitical discussions.
- 侵入 (shinnyuu) — intrusion; trespass; unlawful entry. Often used for physical entry into a prohibited area.
- 侵害 (shingai) — infringement; violation; encroachment. Commonly used for rights or intellectual property.
Kun'yomi (訓読み) — Native Japanese readings
The main Kun'yomi for 侵 is おか.す (oka.su). This reading appears when the kanji stands alone, typically as part of a conjugated verb. The verb 侵す (okasu) directly means "to invade," "to encroach upon," "to trespass," or "to violate," conveying a direct and active sense.
- 侵す (okasu) — to invade; to encroach; to trespass; to violate. (The base verb form).
- 領空を侵す (ryoukuu wo okasu) — to violate territorial airspace.
- プライバシーを侵す (puraibashii wo okasu) — to violate someone's privacy.
Common Words & Compounds
The kanji 侵 forms many important compound words. These are vital for understanding nuanced Japanese, especially in formal or serious contexts. Here, we'll explore some of them, categorized by their usage.
General Invasion & Attack: These terms relate to military actions or direct, forceful entry.
- 侵攻 (shinkou) — invasion; incursion; attack. Often used for military movements.
- 侵略者 (shinryakusha) — aggressor; invader. Refers to a person or entity that carries out an invasion.
- 侵入者 (shinnyuusha) — intruder; trespasser. A person who enters without permission.
Legal & Rights-Related Violations: These compounds focus on infringing upon laws, rights, or established boundaries.
- 侵害 (shingai) — infringement; violation; encroachment. As previously mentioned, it is frequently used for rights, patents, or copyright.
- 侵犯 (shimpan) — violation; infringement; transgression. Similar to 侵害, but often implies a more formal or legal transgression, such as a "boundary violation."
- 不法侵入 (fuhou shinnyuu) — unlawful entry; illegal trespass. A very specific legal term.
- 権利侵害 (kenri shingai) — violation of rights.
Gradual or Subtle Encroachment: These words describe a slower, often less direct, form of intrusion or damage.

Memory Tip
To remember 侵, consider its components: the "person" radical 亻 on the left, and 寖 on the right. Imagine a person (亻) who is creeping in deep or "soaking in" (寖) where they don't belong. This imagery of someone subtly or forcefully entering—or "deeply penetrating"—a space perfectly captures the essence of "invade," "encroach," or "violate." Picture a spy slowly infiltrating enemy lines, or a border guard spotting someone trying to "creep in." The character itself visually suggests someone taking careful, deliberate steps into forbidden territory. This story of stealthy, unwelcome movement helps solidify the kanji's meaning of intrusion and violation.
