hi no hikari muzubi mo aezu shitatareri
from “Haiku Dai-Saijiki” (“Comprehensive Haiku Saijiki”), Kadokawa Shoten, Tokyo, 2006
Fay’s Note: “shitataru” (‘trickle’, or ‘drip’) is a summer kigo. It does not mean raindrop dripping. It means ‘pure water trickling on the mountain side.’ Ancient people felt refreshing when they saw it or heard its sound.
