Meaning
The kanji 監 (KAN) primarily means supervise, observe, oversee, inspect, or superintend. It describes the act of carefully watching over something or someone, often implying authority or responsibility to ensure proper conduct or quality. You'll frequently encounter this kanji in official, legal, and managerial contexts.
Understanding its etymological roots helps explain its visual form. The character 監 is composed of 臣 (shinjin - minister, vassal, or originally an eye looking down) placed above 皿 (sara - dish, vessel). In its ancient form, the 臣 component depicted an eye gazing downwards, symbolizing observation or scrutiny. When combined with 皿, which represents a basin or vessel, the image suggests someone looking intently into a basin of water. This could be to reflect upon something or to observe details within it. This visual combination reinforces the core meaning of careful, authoritative observation and inspection. Over time, this concept evolved into supervising and overseeing.
With 13 strokes, 監 is a kanji of moderate complexity. It is classified as a Jōyō kanji, specifically designated for Grade 8, meaning Japanese students typically learn it in secondary education. This reflects its advanced usage and importance in general literacy.
Readings
On'yomi (音読み) — Chinese-derived readings
The primary On'yomi for 監 is カン (KAN). This reading is by far the most common and appears in nearly all compound words containing 監. It conveys the essence of supervision, observation, and management, reflecting its Chinese origin.
- 監督 (kantoku) — This compound is widely used to mean 'supervision,' 'director,' or 'manager.' For example, a film director is 映画監督 (eiga kantoku), and a sports coach or manager is 監督。
- 監視 (kanshi) — Signifies 'surveillance,' 'monitoring,' or 'watch.' It implies keeping a close eye on something or someone, often for security or control purposes, such as 監視カメラ (kanshi kamera - surveillance camera).
- 監査 (kansa) — Refers to an 'audit' or 'inspection,' especially in financial or organizational contexts. An external audit is 外部監査 (gaibu kansa).
- 監修 (kanshuu) — Means 'supervision' or 'editorship,' often in the context of academic or creative works where an expert oversees the content. For instance, 医学監修 (igaku kanshuu) refers to medical supervision (for a publication).
Kun'yomi (訓読み) — Native Japanese readings
The main Kun'yomi for 監 is かんが（みる） (kanga(miru)), primarily found in the verb form 監みる. This reading is less common than the On'yomi and carries the nuanced meaning of "examining," "considering in light of," or "reflecting upon." While it shares some semantic overlap with 鑑みる (which also means to consider in light of), 監みる specifically emphasizes observing or scrutinizing a situation or past example.
- 監みる (kangamiru) — To examine, to consider, to take into account, to reflect upon. This verb is often used in formal or legal contexts, for instance, when making a decision based on previous cases or precedents. For example, 前例に監みる (zenrei ni kangamiru) means "to consider in light of precedent."

Memory Tip
To remember 監, visualize its components: 臣 (shinjin - an eye looking down or a minister) atop 皿 (sara - a dish or basin). Imagine a strict minister (臣) looking intently down into a dish (皿) of water, perhaps to check its purity or observe reflections within it. This image of careful, authoritative observation directly reinforces the meanings of "supervise," "observe," or "inspect." The minister is ensuring everything is in order, much like a supervisor oversees a project.
