What Is a Kamashiki? The Kettle Rest in Japanese Tea Ceremony
Oct 01, 2026
Quick answer: a kamashiki (釜敷) is the kettle rest placed under the hot kama when the host removes it from the fire during charcoal procedure. It protects the tatami or floor surface while the charcoal and ash are adjusted. Traditional examples are made from materials such as cane, bamboo, woven plant fiber or folded paper.
What is a kamashiki?
The word means, literally, something placed beneath the kettle.
Its job is simple but essential: when the hot iron kama is lifted away from the ro or furo, it needs a stable, heat-conscious surface on which to rest temporarily.
Why is the kettle removed from the fire?
Because the host needs access to the fire during sumidemae.
Charcoal must be added or rearranged, ash may be adjusted and incense may be placed. The kettle therefore has to move out of the way without being put directly onto the tatami.
How does the kettle reach the kamashiki?
With kan, the detachable iron kettle rings.
The rings are fitted through the kettle’s side lugs, allowing the host to lift the hot kama and place it onto the kamashiki.
Is kamashiki the same as gotoku?
No.
- Gotoku — supports the kama over the fire.
- Kamashiki — supports the kama after it is removed from the fire.
Is kamashiki the same as futaoki?
No.
A futaoki is a small rest for the kettle lid and, in many procedures, the hishaku. A kamashiki must support the entire weight and heat of the iron kettle.
What is a kamashiki made from?
There is no single material.
JAANUS notes bamboo and Mino paper. The Metropolitan Museum of Art preserves a Japanese cane kamashiki from around 1775, while Smithsonian collections include bamboo examples from the late Meiji or early Taishō period.
What does a traditional woven kamashiki look like?
Many resemble a compact circular or square mat.
The Met’s ca. 1775 example is a round cane mat about 13.8 cm across. A Smithsonian bamboo example measures roughly 14 cm square and only a few millimeters thick.
Why can something so thin support a hot kettle?
Because the purpose is not to suspend the kettle high above the floor.
The kamashiki creates a sacrificial insulating layer between the hot iron base and the tatami, while distributing the kettle’s weight over a slightly larger area.
What is a paper kamashiki?
A kamikamashiki is a kettle rest made from folded paper.
JAANUS specifically mentions Mino paper as a traditional material. Folded paper can create enough thickness to act as a temporary rest while remaining light, compact and easy to integrate into formal tea procedure.
Can paper really be placed under a hot iron kettle?
Yes, when properly folded and used within the intended procedure.
The kettle is not being set onto an open flame; it has been removed from the fire and rests temporarily. The paper’s layered structure provides separation from the tatami.
Are there luxury kamashiki?
Absolutely.
Urasenke’s Tea Research Museum records a wide range, including imported-style plaited rattan, bamboo-and-rattan examples, a spinning-top-shaped kamashiki favored by Ennōsai and even five-color plaited-string forms.
Why would a simple kettle rest become decorative?
For the same reason other charcoal utensils did.
Once sumidemae moved from backstage preparation into a procedure performed in front of guests, tools for handling the kettle and fire became part of the aesthetic selection.
Does season affect the choice?
It can.
Exact choices depend on school, procedure and the wider toriawase. Different plant fibers, paper colors and formal ranks can change the character of the fire-side utensil set.
Does kamashiki travel in the sumitori?
Yes.
Omotesenke lists the kettle rest among the standard equipment carried in the sumitori, together with charcoal, hibashi, kettle rings, kogo and haboki.
Can kamashiki be used to display other utensils?
Paper kamashiki can have secondary presentation roles.
JAANUS notes that kogo incense containers could be displayed on a paper kamashiki in waiting rooms or shoin-style tea spaces.
Is kamashiki the same as kamasue?
No.
Kamasue refers to a more substantial kettle stand. Kamashiki is the smaller mat or rest associated directly with the temporary handling of the kettle in tea procedure.
Can an ordinary trivet replace it?
Practically, a heatproof trivet can protect a surface at home.
In formal chanoyu, however, the size, material, folding or weaving and handling of the kamashiki belong to the procedure and should follow the school being practised.
Do you need a kamashiki for home matcha?
No.
It becomes relevant when using a traditional kama that is removed from a charcoal fire during sumidemae.
Kamashiki in one sentence
A kamashiki is the small heat-resistant kettle rest of chanoyu, receiving the hot kama when it is lifted away from the ro or furo so the host can work on the charcoal fire safely and neatly.
