Oil Painting Of Geisha with Sensu in Nagoya Japan by Jeffrey Dale Starr

Traditionally, Geisha began their training at a very young age. Some girls were bonded to geisha houses (okiya) as children. These girls were referred to as hangyoku and were as young as nine years old. This was not a common practice in reputable districts and disappeared in the 1950s with the outlawing of child labor. Daughters of geisha were often brought up as geisha themselves, usually as the successor (atotori, meaning "heiress") or daughter-role (musume-bun) to the okiya.

A maiko is essentially an apprentice and is therefore bonded under a contract to her okiya. The okiya supplies her with food, board, tuition fees, kimonos, obis, and other tools of her trade. Her training is very expensive and her debt must be repaid to the okiya with the earnings she makes. This repayment may continue after the maiko becomes a full-fledged geisha and only when her debts are settled is she permitted to move out to live and work independently.

A maiko will start her formal training on the job as a minarai, which literally means "learning by watching". Before she can do this she must find an onee-san ("older sister": an older geisha acting as her mentor). It is the onee-san's responsibility to bring her to the ozashiki, to sit and observe as the onee-san is at work. This is a way in which she will gain insights of the job, and seek out potential clients.

Although minarai attend ozashiki (banquets in which guests are attended by geisha), they do not participate at an advanced level. Their kimono, more elaborate than a maiko's, are intended to do the talking for them. Minarai can be hired for parties but are usually uninvited (yet welcomed) guests at parties that their onee-san attends. They only charge a third of the usual fee. Minarai generally work with a particular tea house (minarai-jaya) learning from the okaa-san (literally "mother," the proprietress of the house). From her, they would learn techniques such as conversation and gaming, which would not be taught to them in school. This stage lasts only about a month or so.

After a short period of time the final of training begins, and the students are called maiko. Maiko (literally "dance girl") are apprentice geisha, and this stage can last for years. Maiko learns from their senior geisha mentor and follows them around to all their engagements. The onee-san and imouto-san (senior/junior, literally "older sister/younger sister") relationship is important. Since the onee-san teaches her maiko everything about working in the hanamachi, her teaching is vital. There are 5 different hairstyles that the maiko wear, that mark the different stages of her apprenticeship. She will teach her proper ways of serving tea, playing shamisen, dancing, casual conversation and more. The onee-san will even help pick the maiko's new professional name with kanji or symbols related to her name.

The production of these folding fans rapidly grew in Kyoto which was long the center of Japanese politics and culture. The fans became popular at the court and among the nobility, and gorgeous decorations evolved with the use of elegantly painted designs and paper sprinkled with gold and silver foil. In the 14th century artisans of Kyoto made folding fans to match the styles of the courtly performing arts of Noh (masked drama) and Buyo (Japanese classical dance) and later the tea ceremony. In the 13th century folding fans were used not only in Japan but were also exported to China. Later the fashion migrated to Europe; even the fancy courtiers of the Bourbon dynasty of France highly prized the colorful Kyo Sensu.

Even today, the Kyo Sensu, which grew up in the rich cultural environment of Kyoto, is still used in daily life, and the artisans apply their creativity to devise new designs. The attraction of the folding fan owes its allure not merely to the superb craftsmanship and decorative skills involving the hand-working of selected materials, but it is a practical device with beauty of both form and function.

Imagawa Ujichika built the original castle at Nagoya around 1525. Oda Nobuhide took it from Imagawa Ujitoyo in 1532, but later abandoned it.

In 1610, Tokugawa Ieyasu ordered the various daimyo to help with the building of a new castle on the site. This new castle was to become the new capital of the existing Owari Province. The source for many of the building materials for the new castle was from the smaller Kiyosu Castle, including Kiyosu castle's tenshu, which was located in the existing provincial capital of Kiyosu. Nagoya castle's reconstruction was completed in 1612.

During the Edo period, Nagoya Castle was the center of one of the most important castle towns in Japan—Nagoya-juku—and it included the most important stops along the Minoji, which linked the Tokaido with the Nakasendo.

Until the Meiji Era, the castle was the home of the Owari Tokugawa clan of the Tokugawa family. It was destroyed by fire during World War II, but the donjon has been rebuilt.

During World War II, the castle was used as the district army headquarters and as a POW camp. During the bombing of Japan, the castle was burnt down in a USAF air raid on May 14, 1945. Due to the destruction caused by the air raid, most of the castle's artifacts were destroyed. Many of the paintings inside, however, survived and have been preserved.

The reconstruction of the donjon was completed in 1959. Today the donjon is a modern concrete building with air-conditioning and elevators. In addition, there are plans to reconstruct the Hommaru Palace, which also was lost to fire during the war. Many of the paintings from this palace also were rescued and replicas of these paintings will be placed in their appropriate locations within the restored palace.

Until the restoration of the Hommaru Palace is completed, many of the objects formerly in the Hommaru as well as replicas of sliding shoji doors and the reconstructed Noh stage can be seen in the Tokugawa Art Museum in Nagoya.
