Stroke Order

Meanings

  • 1) A star-shaped symbol or glyph used in typography and ratings (as an icon for quality or emphasis).
  • 2) A famous or celebrated person when used metaphorically (as in calling someone a ‘star’).
  • 3) Component in compound words referring to constellations, meteor phenomena, and astrology.
  • 4) Technical astronomical sense distinguishing types of stars (used in scientific terms).

Origin

The concept of stars existed in Japan long before writing; after Chinese characters were introduced (early centuries CE) the character 星 (hoshi) was adopted to label visible stars, and it appears in classical poetry, calendrical texts, navigation and later in Edo-period astronomy and popular astrology.

Composition

  • 日 (sun/day) on top and 生 (life/birth) below combine visually in the character to suggest a shining or ‘born’ luminous body, giving the meaning associated with a star.

Usage

Used in everyday speech to talk about the night sky and celestial observations (common and casual), in newspapers and scientific contexts (formal) when referring to astronomical objects, and widely in compound words and names; it also appears in ratings and brand names and can be a surname or given name element, and is read in compounds with the on-yomi sei in technical or Sino-Japanese terms.
💡 Tips
Visualize a little sun (hi) ‘born’ in the sky — that image (sun above life) helps recall 星 (hoshi) means star.

Variations

  • 恒星 (kousei) — fixed star, stellar (astronomical term)
  • 衛星 (eisei) — satellite (literally ‘guard star’)
  • 太陽 (taiyou) — sun (the star at the center of our system)
  • 月 (tsuki) — moon (often treated as a contrasting celestial body)
  • 星形 (hoshigata) — star-shaped

    • 夏 (natsu) – summer
    • の (no) – of

    The noun 「屋上」 means rooftop; the particle で marks the location where the action takes place, so 屋上で = on the rooftop.
