What Is Sukigi? Wooden Kama Supports in Japanese Tea
Oct 01, 2026
Quick answer: sukigi (透木) are wooden support pieces used between a winged tea kettle and the structure that carries it in particular chanoyu arrangements. They provide a different support logic from a gotoku: instead of a three-legged iron trivet holding the kettle from below, a hagama (winged kettle) is supported at its projecting flange by the wooden pieces. Urasenke and Tankosha teaching explicitly covers sukigi handling in both ro and furo practice, so this is not an obscure historical term.
What are sukigi?
Sukigi are small wooden supports placed so that a kettle with a projecting flange can rest on them.
Tankosha’s tea dictionary explains the related term sukigi-gama (透木釜) as a kettle named for being placed against or on sukigi and states that it is therefore necessarily a hagama—a kettle with a wing-like flange.
Why does the kettle need a flange?
Because the support acts on that projecting part of the kettle.
A standard kama can be carried by a gotoku from below. With sukigi, the important contact is between the wooden supports and the kettle’s flange. The geometry of the kettle therefore determines whether the system can work.
How is sukigi different from a gotoku?
A gotoku is an iron trivet, usually with three legs, placed in the hearth or brazier to support the kettle.
Sukigi are wooden supports used with a winged kettle. They change the points at which the kettle’s weight is carried and leave the centre beneath the kettle free of a gotoku.
This is a structural distinction, not merely a decorative one.
How is sukigi different from kirikake?
Kirikake is another no-gotoku solution, but it works differently.
In a kirikake arrangement, the matched kettle body and furo are formed so that the kettle rests directly on the brazier. With sukigi, separate wooden pieces sit between the winged kettle and its supporting surface.
So both can remove the need for a gotoku, but they should not be treated as the same structure.
Are sukigi used only with the ro hearth?
No.
This is especially important for the present furo branch of the knowledge graph. Tankosha’s 2024 Urasenke teaching series includes a dedicated section titled “Handling Sukigi — Furo”, supervised by Sen Sōshitsu and instructed by the Konnichian gyōteibu. The same series also covers sukigi handling for the ro.
That gives unusually clear contemporary evidence that Urasenke teaches both settings.
When are sukigi used in Urasenke ro practice?
Urasenke commonly associates sukigi with the late-ro season, particularly April, as the tea year approaches the change to furo.
An Urasenke headmaster Q&A discusses the April use of a sukigi-gama and historical evidence for the arrangement. That timing should be attributed to Urasenke practice rather than silently generalized to every tea lineage.
How old is the sukigi idea?
It is not a modern convenience.
In an Urasenke headmaster Q&A, Sen Sōshitsu refers to a 1569 tea record by Tsuda Sōgyū describing a low, winged kettle set at the hearth. The answer explains that the historical setup is difficult to understand without some form of wooden spacing beneath the kettle flange and concludes that sukigi-type use was already spreading during the Eiroku period.
Does “sukigi” literally mean transparent wood?
No useful interpretation comes from reading the modern characters literally.
The same Urasenke Q&A notes that the word may have developed from shikigi (敷木), “wood laid underneath.” That etymology is presented as a possibility, not an absolute certainty, so it is best kept in that form.
Why leave a gap under the kettle?
Airflow is one practical reason.
The Urasenke Q&A points out that placing a winged kettle directly against the hearth structure would restrict the flow of air needed for the fire. Sukigi creates the necessary spacing while supporting the kettle.
This is a good example of a chanoyu detail whose visual form comes from a practical fire-management problem.
What is a sukigi-gama?
A sukigi-gama is a kettle intended for this support system.
Tankosha’s dictionary is precise: because the kettle is supported through sukigi, it is necessarily a hagama. The projecting wing or flange is not an optional decoration; it is part of how the kettle meets the support.
What is a sukigi furo?
Tea-utensil references use the name for furo designed with a broad, flat shoulder or upper surface that can receive the wooden supports and the flange of a suitable kettle.
That specialist description is helpful for understanding the geometry, but school-specific handling should still be learned from the relevant lineage. The important general point is that a furo can be designed around sukigi as its kettle-support interface.
Does sukigi determine the haigata?
No.
Sukigi describes the support relationship. Haigata describes the shaped ash field. Those are separate dimensions, even though they meet physically inside the same fire arrangement.
As with the furo taxonomy developed in this library, support structure, material, ash form, season and formal register should be recorded separately.
Is sukigi still taught today?
Yes.
Tankosha’s Urasenke curriculum books currently teach sukigi handling in both ro and furo. The 2024 volume for April covers the ro version; the July volume covers the furo version. Tankosha’s broader Chadōgu Hyakka volume on kama, ro and furo also includes sukigi handling among its practical topics.
Why is sukigi important for understanding chanoyu?
Because it makes the kettle-support problem visible.
A casual observer may see only “a kettle above a fire,” but chanoyu has several structurally different ways to achieve that: gotoku support, kirikake direct support, suspension in a hanging-kettle arrangement, and sukigi support through a kettle flange. Those systems change the hardware, the space around the fire and the procedures used when handling the kettle.
Do you need sukigi for home matcha?
No.
Sukigi becomes relevant when studying full chanoyu fire practice, kettle construction and seasonal ro/furo procedures. It is not required for whisking matcha at home.
Sukigi in one sentence
Sukigi are wooden supports used with a winged kama so that the kettle is carried at its flange rather than by a gotoku, a support system that remains explicitly taught in modern Urasenke ro and furo practice.
