Meaning
宮 covers four core meanings: palace, shrine, imperial residence, and royal court. Each points to the same idea — a grand, protected space set apart from ordinary life. In Shinto contexts, it designates high-ranking shrines. In anatomy, it appears in the word for uterus (子宮), reflecting the idea of an inner chamber that shelters life. In classical literature and historical texts, it refers to the living quarters of nobility or the emperor himself.
Break 宮 apart and the meaning becomes visible: two components, each doing real work. The top element is 宀 (ukanmuri), the "roof" radical, which appears in many kanji associated with buildings and sheltered spaces — such as 家 (house), 室 (room), and 宿 (lodging). The lower element is 呂, which depicts two connected rooms or chambers placed side by side. Together, 宮 visually encodes the concept of a roofed structure containing multiple interconnected rooms — the defining architectural feature of a palace or grand shrine complex. Ordinary homes have a single room; palaces are distinguished by their many halls and chambers. The kanji elegantly captures this distinction in its very shape.
With 10 strokes, 宮 is taught in grade 3 of Japanese elementary school. It is a Jōyō kanji with the radical 宀 (roof). Both 宮崎 (Miyazaki) and 宮城 (Miyagi) carry this kanji — places with old ties to shrines or royal ground. It threads through vocabulary on the imperial family, Shinto religion, and classical history.
Readings
On'yomi (音読み) — Chinese-derived readings
宮 has three on'yomi readings. Which one applies depends on the specific compound — frequency and context are your best guides at the N1 level.
キュウ (kyuu) is the most common on'yomi, covering royal palaces, imperial courts, and a few anatomical or abstract terms:
- 宮殿 (kyuuden) — palace; a grand royal building with many halls
- 宮廷 (kyuutei) — royal court; the imperial court and its attendant culture and ceremonies
- 子宮 (shikyuu) — uterus; the womb (medical term)
- 迷宮 (meikyuu) — labyrinth, maze; also used figuratively for an unsolvable mystery
- 離宮 (rikyuu) — detached palace; an imperial villa separate from the main palace
- 王宮 (oukyuu) — royal palace of a king (non-imperial)
グウ (guu) belongs to the most prestigious Shinto shrines and to imperial family titles. It carries a ceremonial weight absent from everyday speech:
- 神宮 (jinguu) — grand imperial shrine; e.g., Ise Jingū, the most sacred Shinto shrine
- 宮司 (guuji) — chief priest of a Shinto shrine
- 東宮 (touguu) — Crown Prince; the Eastern Palace (classical designation)
クウ (kuu) survives in just one common term:
- 宮内庁 (kunaichou) — Imperial Household Agency; the government body that manages all affairs of the imperial family
Kun'yomi (訓読み) — Native Japanese readings
みや (miya) is the native Japanese reading — and one of the richest in cultural meaning. It refers to a high-ranking Shinto shrine, a respectfully-addressed member of the imperial family, or a sacred imperial residence. Place names and proper nouns across Japan are saturated with it. Learn this reading and a large slice of Japanese geography starts to make sense.
- 宮参り (miyamairi) — a newborn's first shrine visit, traditionally performed about one month after birth
- お宮 (omiya) — honorific and affectionate term for a Shinto shrine
- 宮さま (miyasama) — an extremely respectful form of address for imperial family members

Memory Tip
Picture 宮 as a bird's-eye view of a grand shrine or palace. The top component 宀 is the sweeping, protective roof — wide and curved, exactly like the roofs you see on shrine gates and castle towers. Below it, 呂 shows two separate rooms or chambers placed side by side, like the many interconnected halls of an imperial complex. Put them together: a roof sheltering many rooms = a palace or grand shrine. For みや (miya), use place names: 宮崎 (Miyazaki) and 宮城 (Miyagi) both carry this kanji, each with old ties to shrines or royal ground. Any place name ending in -miya has 宮 in it. And 子宮 (uterus) sticks easily: the womb is literally the child's palace — a protected inner chamber, the same concept at 宮's core.
