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.
Monmon is a Japanese term for tattoo, and a monmon cat is a cat with tattoos. They were designed by Horitomo, a Japanese tattoo artist well known for his hand work (tebori) and his monmon designs. He published a book entitled Monmon Cats and has inspired other tattoo artists around the world.
Monmon cats are usually done in traditional Japanese style, and usually have their own Japanese tattoos. They can also be done realistically, in black and grey, and have other tattoos such as American traditional, flowers, and skulls.
