"Famous Heroes of the Kabuki Stage Played by Frogs," Utagawa Kuniyoshi, c. 1875.
Utagawa was sometimes dissatisfied and disaffected with the shogunate in Japan, which led him to create some stunning works of caricature, which can be seen here. Here we have an assortment of scenes from various kabuki plays, all apparently dealing with dramatic deeds by samurai...only with frogs.
These were the days of the Tenpō Reforms, which cracked down on entertainment and banned luxury goods. Kabuki actors were required to wear hats outside lest they be too conspicuous, and the content of ukiyo-e art and popular literature was regulated.
The censorship had the unintended consequence of forcing Utagawa to be very creative and sneaky with his material. Caricature such as this was a veiled criticism of the shogunate, and while it technically evaded the censors, the public ate it up, along with other caricatures he did.
So we can add Utagawa to the Caricature Hall of Fame, with Goya and Daumier!
Interestingly, this print is commonly dated to c. 1875, but Utagawa died in 1861, so I assume this was a design he put together that was printed posthumously.
