It's spelled "geisha," at least in English. And I don't know.

The Geisha is a courtesean of sorts, It is a very ritualized exsistence. They are entertainers that know the rituals of serving tea, playing instruments. A Geisha House was basicaly a brothel.+5

Geisha - (Gei) meaning "art" and (sha) meaning "person". Geisha were considered to be living breathing walking art. At a very young age, most girls moved into an Okiya (Geisha house) where they would be called "Maiko" while they studied and went to school to become Geisha. They become very disciplined and learn very intricate ways of doing everything from dancing to serving tea. Geisha do not engage in paid sex with clients. Their purpose is to entertain their customer, be it by dancing, reciting verse, playing musical instruments, or engaging in light conversation. Geisha engagements may include flirting with men and playful innuendos; however, clients know that nothing more can be expected. In a social style that is common in Japan, men are amused by the illusion of that which is never to be. Geisha's are often confused with Oiran, who also wore eloborate kimono and painted their faces, but Oiran sold their bodies as prostitutes. Geisha did not. In fact, Maiko sold their virginity to the highest bidder in order to become a Geisha. After, she merely entertained. Geisha are expected to be single women; those who choose to marry must retire from the profession. It was traditional in the past for established geisha to take a danna, or patron. A danna was typically a wealthy man, sometimes married, who had the means to support the very large expenses related to a geisha's traditional training and other costs. This sometimes occurs today as well, but very rarely. A geisha and her danna may or may not be in love, but intimacy is never viewed as a reward for the danna's financial support. The traditional conventions and values within such a relationship are very intricate and not well understood, even by many Japanese.
