Two Seasonal Worlds
Tea practitioners traditionally divide the year into the sunken-hearth season and the brazier season. During colder months, a hearth built into the floor heats the water and provides the room’s only warmth. In warmer months, water is heated in a raised brazier.
There is even a transitional solution: when the brazier is not warm enough but the hearth is too hot, the hearth may be covered and the brazier placed above it.
Objects That Feel the Weather
Seasonal awareness reaches into the smallest details. Winter uses neriko, pellet-shaped incense, while summer calls for incense such as jin or byakudan. Other fragrances mark the transition between seasons.
Tea bowls change too. Deep, cylindrical bowls help retain heat in winter. Shallow bowls allow tea to cool more quickly during summer. Clothing follows the same logic: people wear layered kimono in colder months and single-layer garments in summer.
Flowers must also reflect the season. Tea flower arrangements, or chabana, are deliberately simple and should give the impression that the flowers are still growing naturally outdoors. Out-of-season materials are avoided.
Even the tatami layout may be altered. In this tradition, seasonal change is not scenery in the background—it is built into the ceremony’s physical structure.
The result is a ritual that teaches participants to notice time passing, not as an abstraction, but through warmth, scent, texture, color, and the shape of a bowl.
