Meaning
Welcome! Today, we're taking a closer look at the kanji 没 (ぼつ). This character carries a powerful sense of finality and disappearance. Fundamentally, 没 means 'to sink,' 'to submerge,' or 'to disappear.'
You can imagine something vanishing beneath the surface—be it water, earth, or even the flow of time. Beyond physical submergence, its meaning extends to concepts like 'to die,' 'to be lacking,' 'to be rejected,' or 'to be confiscated.'
This N1 level kanji has 7 strokes. You'll encounter it in more advanced texts and nuanced expressions. While it is part of the Joyo (common use) kanji list, it doesn't have a specific school grade assigned like simpler kanji, primarily due to its higher complexity and abstract applications.
Its visual components offer insight into its origin. The left side is the 'water' radical (氵), clearly pointing to liquidity and submergence. The right side, 乂 (which sometimes appears as 殳 in other kanji but is stylized here), is thought to represent something being covered, crossed out, or going under. Picture the water radical (氵) actively overwhelming or covering the element on the right.
This visual perfectly encapsulates the feeling of something being 'lost to the water' or 'covered and made to disappear.' This applies whether something is physically sinking, a project is rejected, or a family line falls into ruin. Grasping this connection to water and being 'covered' or 'gone' is key to understanding its varied meanings.
Readings
On'yomi (音読み) — Chinese-derived readings
The On'yomi readings are the primary way 没 is used in Japanese, especially in compound words. You'll most often find it with the reading ボツ (botsu), and occasionally モツ (motsu).
ボツ (botsu)
This is the most common and widely used On'yomi for 没. It appears in a broad range of words related to sinking, disappearing, failing, or being absorbed. When you hear ボツ, you should generally think of something being 'lost,' 'rejected,' 'submerged,' or 'deeply involved.'
- 没落 (botsuraku) — downfall, ruin, collapse. This term describes a family, a nation, or a business falling into decline, like a once-powerful 貴族 (aristocratic) family experiencing 没落.
- 没収 (bosshū) — confiscation, forfeiture. This is often used in legal or official contexts when property or items are taken away, such as a criminal's 資産 (assets) being 没収される.
- 没頭 (bottō) — absorption, immersion, devotion. Here, the meaning shifts to being 'submerged' or 'deeply lost' in an activity or study. For instance, a student might 研究に没頭する (immerse themselves in research).
モツ (motsu)
While a valid On'yomi, モツ is considerably rarer in everyday modern Japanese compared to ボツ. You might encounter it in specific, often more technical or archaic terms. It also carries the core meaning of sinking or disappearing, but its usage is far more limited.
- 没薬 (motsuyaku) — myrrh. This botanical term refers to the resin from a specific tree, primarily used in medicine or perfumery. It's a prime example of a word where モツ is used, though it's not one you'd hear frequently in casual conversation.
- Even if a dictionary lists モツ, the actual compound might use ボツ due to sound changes. For instance, in 埋没 (maibotsu), 没 is read as ボツ. Developing a feel for these nuances comes with exposure, but for general understanding, prioritize ボツ.
Kun'yomi (訓読み) — Native Japanese readings
Interestingly, 没 is one of those kanji that functions primarily through its On'yomi readings. It doesn't have a commonly recognized standalone Kun'yomi, unlike simpler kanji such as '食べる (taberu)' or '飲む (nomu).' While its meaning is closely tied to verbs like 'sink (沈む)' or 'drown (溺れる),' these are represented by distinct kanji with their own readings. You won't typically see 没 by itself being read as しずむ or おぼれる.
Its connotation of 'lacking' or 'not' is always expressed within compounds, never as a direct verb or adjective reading for the kanji itself.
Common Words & Compounds
To deepen our understanding of 没, we'll examine how it combines with other kanji to form powerful and expressive words. These examples are grouped by theme to illustrate the nuances of its meaning.
Thematic Group: Disappearance & Sinking
没落 (botsuraku) — downfall, ruin, collapse. This often describes the decline of a social class, a family, or an empire, such as the 没落 of a once-proud dynasty.
沈没 (chinbotsu) — sinking, foundering. This term is almost exclusively used for ships or other vessels going down in water, like the 豪華客船 (luxury liner) that 沈没した (sank).
埋没 (maibotsu) — burial, being buried, submergence. This implies being covered by earth or hidden from view. It can also be used figuratively, for example, for a 才能 (talent) that remains 埋没したまま (buried and unrecognized).
日没 (nichibotsu) — sunset. The sun 'disappears' below the horizon, marking the end of the day. For example, 日没までには帰ろう (Let's return by sunset).

没頭 (bottō) — absorption, immersion, devotion. To be so engrossed in something that you 'lose yourself' in it. A scientist might 実験に没頭する (be absorbed in an experiment).
没我 (botsuga) — self-abnegation, selflessness, absorption to the point of losing oneself. This is a deeper form of immersion where one's ego disappears, often associated with spiritual or artistic pursuits, like a musician playing with 没我の境地 (a state of selfless absorption).

Memory Tip
To remember 没, let's focus on its visual components. The left side is the 'water' radical (氵), which unmistakably signifies water. The right side, 乂, can be interpreted in a couple of helpful ways. Imagine it as a person whose legs are crossed, indicating they've gone 'under' or are 'gone.' Alternatively, you can see it as a giant 'X' mark, symbolizing something being crossed out, rejected, or having disappeared.
So, picture a person (乂) falling into the water (氵) and completely disappearing. Or, visualize a task that was marked with an 'X' (乂) and then figuratively thrown into the water (氵), causing it to disappear or be rejected. Either way, the image of something being covered by water and ceasing to exist is key!
