Stroke Order

Meanings

  • late-night hours, typically around midnight to just before dawn, used in schedules, media, and casual reference
  • a sense of quiet or stillness associated with the deepest part of the night, sometimes implying privacy or introspection

Etymology

深 shin + 夜 ya form a straightforward on’yomi compound; the combined pronunciation shin’ya reflects a common pattern where two kanji read with on readings fuse into a single, stable term for the late-night period.

Composition

  • 深 = deep, profound;
  • 夜 = night;
  • their combination conveys the notion of the night being deep or advanced into the darkest part of the night, i.e., the late-night period

Usage

Used in both formal and informal contexts to denote the late-night time window, including schedules, broadcast descriptions, and discussions of nocturnal work or activities; commonly attached to time expressions or compound forms like 深夜帯, and appears in written and spoken Japanese without requiring explanatory context.
💡 Tips
Mnemonic: picture the 深 as a deep, dark ocean and 夜 as night; together they cue the idea of the night that is deepest, the late hours when the world slows down, with shin’ya marking the boundary between day and pre-dawn.
