Ono no Komachi Praying for Rain

In this image, a woman who is meant to represent poet Ono no Komachi is about to set a toy ship in the water.
Behind her, an attendant holds up an umbrella to protect her from the rain. The poem above is a play on two names for Japan:

There is indeed reason to have bright sunlight here in
the Land of the Rising Sun,
Yet why is it also called “Under Heaven (Rain)?”

(Translation by Kenji Toda)
(The Japanese words for heaven and rain are homonyms.)
