in the outcasts' town
a Buddhist banner...
the frosty month
eta mura [no] okoo nobori ya o-shimtsuki
by Issa, 1820
The "frosty month" is a euphemism for Eleventh Month in the
traditional Japanese calendar.This haiku refers to the outcasts (eta).
In Issa's time, they performed "unclean" jobs such as disposing of
dead animals, working with leather, and executing criminals.
