Meaning
宗 covers two broad territories in modern Japanese. The first is organized religion — sects, denominations, and systems of belief that have shaped Japanese society for over a millennium. The second is more abstract: the essential point, founding origin, or central purpose of something. Both meanings share a common thread: whatever lies at the core of a tradition.
Two components build the character. 宀 (ukanmuri, the roof radical) arches over 示 (an altar or sacred symbol). Together they picture a sacred altar sheltered beneath a roof — the ancestral shrine at the center of traditional household life. Families gathered there to honor the dead and maintain their sense of lineage. From that image, the kanji extended outward to mean religion, sect, the head of a lineage, and the foundational essence of any tradition.
宗 has 8 strokes and appears on the Jōyō (常用) kanji list as a secondary-education character, typically introduced at the junior-high level. On the JLPT scale it sits at N1, among the most advanced characters. It turns up regularly in newspapers, religious texts, cultural commentary, and formal documents.
Readings
On'yomi (音読み) — Chinese-derived readings
宗 has two on'yomi readings: シュウ (shū) and ソウ (sō). Each clusters around a distinct area of meaning.
シュウ (shū) is the more common of the two. It dominates in words related to religious sects, denominations, doctrines, and conversion.
- 宗教 (shūkyō) — religion, faith; the broadest term for any organized system of belief and worship
- 宗派 (shūha) — religious sect or denomination, such as different schools of Buddhism
- 宗旨 (shūshi) — religious doctrine or creed; also used metaphorically for someone's personal principles
- 改宗 (kaishū) — religious conversion, switching from one faith to another
- 禅宗 (Zenshū) — Zen Buddhism, one of the most influential Buddhist schools in Japan
ソウ (sō) is less common but important. It appears in words about the head of a lineage or grand master of a traditional art — the founding authority at the top of a practice.
- 宗家 (sōke) — the head family or founding house of a martial art, tea ceremony school, or other traditional practice
- 宗主 (sōshu) — suzerain, paramount leader; historically used for a dominant state in a tributary relationship
- 宗匠 (sōshō) — grand master or head teacher in traditional arts such as tea ceremony, haiku, or flower arranging
Kun'yomi (訓読み) — Native Japanese readings
The kun'yomi reading is むね (mune), meaning the essential point, purport, or fundamental intent of something. Relatively rare in modern spoken Japanese, it appears in formal writing, classical texts, and legal or official documents.
- 宗 (mune) — the essential point, the gist; used in formal and literary contexts
Note: 旨 (also read むね) overlaps in meaning and is somewhat more common in everyday modern usage. Knowing both pays off when reading older texts or formal Japanese.

Memory Tip
Break the kanji into its two parts: the roof (宀) on top and the altar (示) below. Picture a traditional Japanese room tucked under the eaves — quiet, dimly lit, with incense burning before a wooden altar holding photographs of ancestors. This room is the spiritual center of the home, the place where a family's origin is kept alive. That image is 宗: a roof over an altar, the sacred core of a lineage.
