The mon (family crest) of Tomoe Gozen the beautiful and brave, the most famous of all of the female samurai. Tomoe was the wife of Minamoto Yoshinaka or Kiso and she fought alongside her husband in every one of his battles. Even in his last battle when his samurai had been reduced to only five Tomoe was still among them. Only speculation and rumor have any say on how she met her end but what we do know is that this Japanese woman was as brave and as skilled as any man.
The design in this set of dice often refered to as a Tomoe design was used by many clans, many samurai, and even groups of wako (Japanese pirates) used this design. This design is also one of the symbols that represents Hachiman one of the Japanese gods of war.
Almost all mon can be found to be used by many different samurai throughout the centuries.
Another great family to have this as their mon was the Tanaka for example.
