The Ueda Sōko Tradition of chanoyu, or tea ceremony, is a cultural aesthetic practice that originated within the samurai nobility of feudal Japan. The school is commonly called the Ueda Sōko Ryū or Ueda Ryū (Ryū meaning "Tradition" or "School"). The founder from whom the Tradition takes its name is Warring States period warlord Ueda Sōko. The customs, etiquette and values of the samurai are woven throughout all aspects of the school's practice that has continued unbroken for over 400 years.

Ueda Sōko-Ryū 上田宗箇流 is a school of Japanese tea ceremony that originated within the samurai class of feudal Japan. The school is commonly called the Ueda Sōko Ryū or Ueda Ryū (Ryū meaning "Tradition" or "School"). The founder from whom the school takes its name is Warring States period (1467-1615) warlord and tea master Ueda Sōko (1563-1650).

The appeal of warrior-class chanoyu lies in the encouragement of self-expression, an interest in contemporary culture, and pursuing the deeper aspects of the self, as taught by Ueda Sōko’s teacher, Furuta Oribe (1543-1615).

Warrior tea aesthetics pursues a beauty that emerges from the interconnected nature of breath, body, art, and the natural world.

The Ueda Sokō Tradition wishes to communicate its art to the current and future generations, contributing to a global culture that furthers the arts, human understanding and peace.
