Omotesenke (表千家) is one of the schools of Japanese tea ceremony. Along with Urasenke and Mushakōjisenke, it is one of the three lines of the Sen family descending from Sen no Rikyū, which together are known as the san-Senke or "three Sen houses/families" (三千家). The name "Omotesenke", literally meaning "front Sen house/family," came into being as a natural occurrence, because of the location of the homestead of this line of the family in relation to that of the line of the family at what originally was the rear (ura) of the Sen estate. The name "Mushakōjisenke" for the other of the three lines of the family derives from the fact that the family's homestead is located along Mushakōji street. History The Omotesenke estate, known by the name of its representative tea room, the "Fushin-an" (不審庵), was where Sen no Rikyū's son-in-law, Sen Shōan, reestablished the Kyoto Sen household after Rikyū's death. It is located on Ogawa street in the Kamigyō ward of Kyoto. Shōan's son Sen Sōtan soon succeeded as the family heir and head of this estate. The next heir to the estate and family tradition was Sōtan's third son, Kōshin Sōsa, counted as the fourth generation in the Omotesenke family line. Sōtan, when he was ready to retire and gave the headship of the family over to Kōshin Sōsa, established his retirement quarters on adjacent property in the north, building a tiny tea room there, the "Konnichi-an" (今日庵). Eventually, Sōtan's youngest son, Sensō Sōshitsu, inherited that part of the estate, which came to be known as the home of the Urasenke. Style There are small stylistic differences between the different schools. For example, the Omotesenke school whisks the tea less than the Urasenke school, creating less foam on the top of the tea. Also, Omotesenke uses both an untreated bamboo chasen and a susudake chasen, or darkened-bamboo tea whisk, while Urasenke uses untreated bamboo for its chasen or tea whisk. The Fushin-an estate, where the 3rd generation, Sōtan, lived until retirement, is the home and headquarters of Omotesenke. The Kitayama Kaikan in Kyoto is a relatively modern Omotesenke facility, where Omotesenke sponsors exhibitions, lectures, and other educational programs for the general public. Levels Licenses or permissions are called kyojō (許状), menjō (免状) or sōden (相伝). They allow students to study certain tea procedures.
