The image of four frogs and a rabbit which are sumo-wrestling.
A frog is defeating a rabbit . I guess, another frog roles as a referee.
The other two frogs are sighting and laughing.
This original image is called "Choju-giga" meaning "Animal Caricatures" which is credited as the oldest work of "manga" in Japan.
