The Fourth Month of the Lunar Calendar (Unohana-zuki)
Painted by Utagawa Toyokuni III Around 1848-1854 (Kaei period) Tokyo Shiryō Collection 07661-C2

As the title "the month of unohana" suggests, this work depicts the scenery of the city of Edo around April. A man is outside a tenemen cutting up a bonito that was bought by all the residents and he will distribute it to them.

This is a work that depicts the scenery in the fourth month of the lunar calendar and draws natural objects which adds poetic charm to this season other than bonito. It is the paper attached inside out to the bottom of the screen towards the left edge.
There is writing on the paper saying "The eighth day of Chihayaburu uduki (the fourth month of the lunar calendar) is a good day and kamisagemushi (maggots) will be punished'. This refers to the popular belief that you could protect against flies by preparing black ink from amacha (sweet tea) brought to houses on the day of Kanbutsu-e ceremony and putting up the paper written with this senryu poem using the ink so that flies will be deterred. In this senryu, kamisagemushi means maggots.
Kanbutsue, also known as the Flower Festival, is a Buddhist festival celebrating the birthday of the Buddha on the eighth day of the fourth month of the lunar calendar. On this day it is custom to receive amacha, so children are said to have waken up early and headed to the temples and prepared ink using this amacha.
