.ころび寝や庵は茶の子の十三夜
korobi ne ya io wa cha no ko no jû san yo
restless sleep--
tea cakes in the hut
for Ninth Month moon
Issa tosses and turns, thinking about the tasty cakes he'll have for the celebration of the full moon of Ninth Month, 13th day.
In the old calendar, there were two harvest moons: the 15th day of Eighth Month (this is the more important meigetsu) and the 13th day of Ninth Month.
