Another popular and traditional theme in Japanese tattoos are Geisha. These women were not the prostitutes or hookers but rather women of culture and refinement that were seen to carry the traditions of the culture. They were often extremely beautiful and talented women they could sing, play traditional instruments, dance and entertain. There of course are tons of traditional woodcuts that feature the "floating world" where the Samurai and Geisha would meet. Many of these woodcuts and themes have been done in tattoo designs. If you are looking for a strong female image then you could always get a design of a samurai's wife who were traditionally trained in martial arts and expected to defend their home if needed.
