Hoken Seido tarot series is a collection of 10 tarot cards inspired by the feudal system in Japan. In Japanese history, Hoken Seido (feudalism) was the arrangement between lords and vassals where the former gave favor by way of land, titles, or prestigious offices in exchange for military service (giri) from the latter.

Geishas were actually amongst the most respected women in Japanese society. As young girls geishas are actually called maikoas. Before becoming a geisha, a maikoa learns how to converse with men, perform traditional dances to perfection, and sing and play stringed instruments.

Geishas were of great use to daimyos. Sometimes, geishas were sent to spy on or assassinate other territorial landlords. Although, any daimyo could easily sense that a geisha was sent to kill him; he had no defense against her. This was attributed to the fact that she was so respectable. The only way he could prevent himself from being killed was to have someone kill her before she could him.
