Death is one of the most culturally loaded concepts in Japanese. The word for four (四, し) is avoided because it sounds like death (死, し). Hospitals skip room numbers containing 4. Wedding gifts never come in sets of four.
Yet death kanji appear everywhere — in news, literature, anime, and daily conversation. This article covers 10 essential kanji spanning death, life, and the afterlife, giving you the vocabulary to understand these concepts as Japanese speakers do.

| 生 | セイ (sei)・ショウ (shō) | い(きる) (ikiru)・う(まれる) (umareru)・なま (nama) | life, to live, to be born, raw | 生活 (せいかつ, life/living), 生まれる (うまれる, to be born), 先生 (せんせい, teacher) | 東京で生まれた — I was born in Tokyo |

死 (Death) vs. 亡くなる (Passing Away) — Levels of Directness
Japanese has a strong hierarchy of directness when talking about death, much like English distinguishes "died" from "passed away":
| Expression | Formality | Nuance |
|---|---|---|
| 死ぬ (しぬ) | Direct | blunt, factual — used for animals, news reports, fiction |
| 亡くなる (なくなる) | Polite | respectful — the standard way to say someone passed away |
| 他界する (たかいする) | Formal | literary — "departed to another world" |
| 逝去する (せいきょする) | Very formal | honorific — used in obituaries and official announcements |
In everyday conversation, 亡くなる is almost always preferred over 死ぬ when talking about a person's death. Using 死ぬ directly about someone who recently died can sound insensitive.
Note: 死ぬ is the only Japanese verb ending in ～ぬ that is commonly used in modern Japanese. Its て-form is 死んで (しんで), following the same pattern as 飛ぶ → 飛んで.
The Number Four Taboo (四 = 死)
The on'yomi of four (四, し) is identical to death (死, し). This homophone has profound cultural effects:
- Hospitals often skip room 4, 42 (死に = "to death"), and 43 (死産 = stillbirth)
- Hotels may skip the 4th floor entirely
- Gift-giving: sets of 4 items are avoided (give 3 or 5 instead)
- Phone numbers: 4444 is considered extremely unlucky
- Counting: people say よん instead of し to avoid the death association
This is why 四 has two readings — し and よん — and why よん dominates in daily counting.
お盆 (Obon) — When the Dead Return
The most important cultural context for death kanji is お盆 (おぼん, the Bon Festival), held in mid-August. Japanese tradition holds that the spirits of deceased ancestors return to visit the living during this period.
Key vocabulary:
| Word | Reading | Meaning |
|---|---|---|
| お盆 | おぼん | Bon Festival (mid-August) |
| お墓参り | おはかまいり | visiting graves |
| 迎え火 | むかえび | welcome fire (to guide spirits home) |
| 送り火 | おくりび | send-off fire (to guide spirits back) |
| 盆踊り | ぼんおどり | Bon dance |
| ご先祖様 | ごせんぞさま | ancestors (honorific) |
During Obon, families clean graves (墓), light fires to welcome spirits (霊), and perform traditional dances. It is one of Japan's three major holiday periods, alongside New Year and Golden Week.
生 — The Most Versatile Kanji
生 is often cited as the kanji with the most readings in Japanese — over 10 distinct readings depending on context:
| Reading | Example | Meaning |
|---|---|---|
| せい | 生活 (せいかつ) | life, living |
| しょう | 一生 (いっしょう) | one's whole life |
| い(きる) | 生きる (いきる) | to live |
| う(まれる) | 生まれる (うまれる) | to be born |
| なま | 生ビール (なまビール) | draft beer |
| は(える) | 生える (はえる) | to grow (plants, hair) |
| き | 生地 (きじ) | fabric, dough |
| お(う) | 生い立ち (おいたち) | upbringing |
The pairing of 死 and 生 forms one of the most fundamental conceptual pairs in Japanese: 生死 (せいし, life and death).
Practice
Q1. What is the polite way to say someone has died in Japanese?
Show answer
亡くなる (なくなる). This is the standard respectful expression. 死ぬ is considered too direct and blunt when referring to a person's death in conversation.
Q2. Why do Japanese hospitals often skip room number 42?
Show answer
Because 42 can be read as し・に (4-2), which sounds like 死に (しに, "to death"). Similarly, 43 (し・さん) can sound like 死産 (しざん, stillbirth). The homophone between 四 (し, four) and 死 (し, death) drives this superstition.
Q3. What is お盆, and which death-related kanji are relevant to it?
Show answer
お盆 (Obon) is the mid-August festival when spirits of the deceased are believed to return to visit the living. Key kanji: 墓 (はか, grave) — families visit graves; 霊 (れい, spirit) — ancestors' spirits return; 魂 (たましい, soul) — the spiritual essence being honored.
Q4. How many common readings does 生 have? Name three with example words.
Show answer
生 has over 10 readings. Three common ones: せい in 生活 (life/living), い(きる) in 生きる (to live), なま in 生ビール (draft beer). It is one of the most versatile kanji in the Japanese language.
Q5. What does 必死 mean, and why is the literal meaning interesting?
Show answer
必死 (ひっし) means "desperate" or "frantic." The literal meaning is 必 (certainly) + 死 (death) — "certain death." The idea is that you're trying so hard it's as if your life depends on it. Originally a shogi (Japanese chess) term meaning a position where checkmate is inevitable.
Summary
- 死 (し) is the core kanji for death; 亡くなる is the polite way to express someone's passing
- The homophone 四 (し) = 死 (し) makes four an unlucky number, affecting hospitals, hotels, and gift-giving
- 生 is one of the most versatile kanji in Japanese with 10+ readings spanning life, birth, growth, and rawness
- 命 (いのち) represents life as precious and irreplaceable, while 運命 (うんめい) means fate
- 魂 and 霊 connect to Japan's rich spiritual traditions, especially visible during お盆 (Obon)
- The pair 生死 (せいし, life and death) is one of the most fundamental conceptual oppositions in Japanese
