northern wind in early autumn
A rare, poetic term for a north wind that blows when wild geese begin to migrate south in early autumn. Mostly encountered in classical literature or seasonal haiku vocabulary.
When the kariwatashi blows, autumn deepens further.
Compound of 雁 (kari, 'wild goose') and 渡し (watashi, 'crossing' or 'sending across'), referring to the wind that accompanies the geese's southward migration in early autumn. The exact historical origin is uncertain, but it is a traditional seasonal word (kigo) in Japanese poetry.
