Meaning
The kanji 嗣 (シ) primarily means heir, successor, and to inherit or succeed. It emphasizes continuation, especially regarding lineage, family headship, or an official position. Unlike more general terms for succession, 嗣 often implies a formal, legitimate, and often hereditary transfer of status or property. It also conveys a sense of duty and the preservation of a family line or tradition.
Its etymological roots offer a fascinating insight. The character 嗣 is a compound of two elements: 司 (つかさ), on the left, meaning 'to manage,' 'to oversee,' or 'an officer,' and 冊 (さつ), on the right, meaning 'a volume,' 'a book,' or 'bamboo slips tied together for writing.' Historically, 冊 represented official documents, registers, or ancestral records. Based on this, 嗣 can be understood as 'one who manages the official records or affairs (司) related to succession or lineage (冊).' It can also mean 'a person who inherits responsibilities or a position as recorded in official registers.' Thus, the visual combination connects the idea of administration or leadership (司) with the official documentation and continuity of lineage (冊). This leads to the comprehensive meaning of a legitimate successor or heir who formally takes over a position or heritage.
The kanji 嗣 has 13 strokes. It is an advanced kanji, corresponding to the JLPT N1 level, and is therefore not assigned a specific grade level within the Japanese school system (Kyoiku Kanji).
Readings
On'yomi (音読み) — Chinese-derived readings
The sole commonly used on'yomi for 嗣 is シ (shi). This reading appears in most compound words containing 嗣, underscoring its formal, academic, or historical usage.
シ (shi): This reading is central to terms of succession, specifically regarding family lineage, imperial succession, or formal appointments. It often appears with other kanji to specify the type of heir or the act of succeeding.
継嗣 (keishi) — heir, successor. This common compound refers to a person who succeeds another in a position or inheritance. The 継 (kei) emphasizes 'continuation' or 'succession' of the line.
後嗣 (kōshi) — successor, heir. This term often refers to the person who comes 'after' (後) to assume a position, especially in a family or lineage.
皇嗣 (kōshi) — Imperial heir. This specific term refers to the successor to the imperial throne. Currently, it refers to Prince Akishino, the brother of the reigning emperor, who is known as 皇嗣殿下 (Kōshi Denka). This highlights the highest form of national succession.
Kun'yomi (訓読み) — Native Japanese readings
The kanji 嗣 has no commonly used stand-alone kun'yomi (native Japanese reading). Although some dictionaries might list obscure or historical kun'yomi such as つぐ (tsugu), its meaning is almost exclusively conveyed through its on'yomi in compounds. When expressing the concept of 'to succeed' or 'to inherit' in native Japanese words, other kanji like 継 (つぐ) are typically used.

Memory Tip
To remember 嗣, visualize its two components: 司 (manage, officer, administer) and 冊 (book, scroll, register). Imagine an officer (司) meticulously updating the official register (冊) or family tree book. This officer carefully records the name of the new heir or successor. The combination visually tells the story of someone officially taking over a position, ensuring the continuation of a lineage as documented in official records. So, "The officer (司) uses the official book (冊) to determine and record the heir (嗣)."
