Meaning
The kanji 嚇 (kaku) primarily means intimidate, threaten, bluster, and coerce. It describes the act of using words, shouts, or a menacing demeanor to instill fear or force someone into submission. This kanji is a compelling example of a phono-semantic compound (形声文字, keisei moji), where one part suggests the meaning and the other hints at the sound.
Its visual composition offers clear insights. The left-hand radical, 口 (kuchi), means 'mouth.' This clearly signals the kanji's connection to vocalization, speech, or sounds. The right-hand component, 赫 (kaku), is also a kanji in its own right, meaning 'radiant,' 'brilliant,' 'awe-inspiring,' or 'intensely red.' While 赫 provides the on'yomi sound 'kaku,' it contributes a significant semantic layer.
Imagine a face turning intensely red with anger, eyes glaring, and a mouth wide open, shouting aggressively. This 'radiant' or 'intensely vivid' aspect, combined with the 'mouth,' powerfully suggests a vocal action. It's not just loud, but terrifying, awe-inspiring, or menacing in its intensity.
Therefore, 嚇 can be understood as using one's mouth in an 'awe-inspiring' or 'intense' way to threaten or intimidate. It's not a simple shout, but one charged with malice or aggressive intent. Classified as JLPT N1, this kanji indicates an advanced level of usage in Japanese. With 18 strokes, it has a relatively high count, reflecting its complex structure. Though not taught in elementary school, its components are common. Its radical, 口 (kuchi), the 'mouth' radical, further emphasizes its link to speech and vocal actions.
Readings
On'yomi (音読み) — Chinese-derived readings
The primary on'yomi reading for 嚇 is カク (kaku). This reading commonly appears in various compound words, especially those found in more formal, academic, or journalistic contexts. These words often relate to threats, intimidation, and expressions of strong anger or a menacing attitude.
- 威嚇 (ikaku) — intimidation; threat; menace. This is one of the most common compounds, referring to actions meant to frighten or coerce, such as a lion's roar (ライオンの威嚇).
- 恐嚇 (kyoukaku) — blackmail; extortion; menace. This term carries a stronger connotation of illegal or malicious threats, often involving money or information (e.g., threatening to reveal a secret unless paid: 秘密を漏らすと恐嚇する).
- 嚇怒 (kakudo) — furious anger; raging indignation. This compound describes a state of intense, intimidating anger, often expressed vocally (e.g., a king's furious decree: 王の嚇怒の御触れ).
- 恫嚇 (doukaku) — intimidation; threat; coercion. Similar to 威嚇, but often implying a more overt and deliberate attempt to instill fear (e.g., a dictator's oppressive policies: 独裁者の恫嚇政策).
Kun'yomi (訓読み) — Native Japanese readings
The kun'yomi readings for 嚇 are おど.す (odo.su) and おど.かす (odo.kasu). These readings directly tie to verbs meaning "to threaten," "to intimidate," or "to scare." It's important to note that in modern Japanese, 脅 (kyou) is far more commonly used for these verbs (e.g., 脅す, 脅かす) instead of 嚇.
- 嚇す (odosu) — to threaten; to intimidate. This verb refers to the act of making threats or using menacing words/actions to frighten someone. Though 脅す is the standard, 嚇す, with its component 赫, clearly conveys a blustering, more intense form of threatening.
- 嚇かす (odokasu) — to scare; to startle; to frighten. This verb focuses more on the act of causing fear or startling someone, often with a sudden action or loud sound. Like おどす, 脅かす is the more common verb in practice.
- 嚇し文句 (odoshi monku) — threatening words; blustering remarks. This compound directly uses the kun'yomi to describe actual threatening or blustering remarks.

Memory Tip
Remember 嚇 by visualizing its components: the 口 (mouth) radical on the left and 赫 (radiant, awe-inspiring, red) on the right. Picture a character in an anime or drama whose face turns 赫 (intensely red) with anger. Their 口 (mouth) is wide open, letting out a terrifying, awe-inspiring shout. This outburst is meant to intimidate or threaten. The sheer intensity of their vocal rage seems to radiate, signifying extreme anger and menace. Think of it as a 'mouth radiating menace.' This vivid image helps connect 嚇's visual form with its meaning of blustering and threatening.
