Archaic term for the full moon, particularly the harvest moon. In modern Japanese, 満月 is the standard word. 望の月 may still appear in classical poetry, historical texts, or traditional contexts like 十五夜.
The full moon shone beautifully in the night sky.
望 (mochi) is an old reading of 望 meaning 'full moon', and 月 (tsuki) means 'moon'. The exact historical derivation is uncertain, but the term is associated with the lunar calendar and traditional moon-viewing customs.
