dew-covered lodging; place wet with dew
Archaic poetic expression for a temporary shelter or resting place exposed to the night dew, often evoking a sense of transience or rustic simplicity.
露の宿 was used in old waka and haiku to express a fleeting traveler's lodging.
Compound of 露 (tsuyu, 'dew') + の (no, possessive particle) + 宿 (yado, 'lodging'). The exact historical origin is uncertain, but it appears in classical poetry as a metaphor for impermanence.
