Frogs are a common subject in Japanese irezumi. These frogs are often seen holding leaves, instruments, food, or other household items. They are also often dressed as samurai; katana and all.
These frogs are largely based off of woodblock prints painted by Kawanabe Kyôsai. Kyôsai painted a number of frogs, but his most famous piece is called “Fashionable Battle of Frogs (Fûryû kaeru ôgassen no zu)”.
These frogs are mainly done in a traditional Japanese style, though they can also be done as more American traditional, or neo traditional.
They are usually done with full colour, with a similar colour palette to the paintings.
Some of these frogs even have their own irezumi. Usually flower designs that are simple for the artist to make small.
