Kaigu is a matched set of four — water jar, waste-water vessel, ladle stand, and lid rest — in the same material and design, used in the highest procedures such as the daisu and the full display on the long board. It symbolises the summit of formality among tea utensils. Only when all four are present is the set called kaigu, and the beauty of the matching is itself the object of appreciation.
History
Kaigu derives from a set used in the tea observances of Song and Yuan Zen temples and was organised in Japanese practice alongside the systematisation of the daisu procedures. Metal sets in bronze and sahari alloy were long regarded as the most formal, and from the Momoyama period ceramic sets appeared as well.
In practice
A kaigu is not assembled gradually; it is acquired or commissioned as a set, which is part of why it functions as a marker of formality.
