Omotesenke; a major school of Japanese tea ceremony
One of the three major schools of Japanese tea ceremony, tracing its lineage directly back to the tea master Sen no Rikyu through the main line of the Sen family. Known for a reticent, understated style of preparing matcha, and for reading the word 茶道 as さどう rather than ちゃどう.
表千家 is one of the three major schools of Japanese tea ceremony (三千家), tracing its lineage directly back to the tea master 千利休 through the Sen family's main house.
Cultural note
Among the Sen family schools, 表千家 reads 茶道 as さどう, while 裏千家 reads it as ちゃどう - a small but well-known difference among practitioners.
