What Is a Ryukyu Furo? The Windowed Kirikake Brazier in Japanese Tea
Oct 01, 2026
A Ryūkyū furo (琉球風炉) is a type of metal brazier used in chanoyu. It has a short, rounded body, long feet and distinctive openings at the front and back.
The traditional form is also a kirikake brazier: the matching kettle fits directly onto it instead of resting on an ordinary gotoku trivet.
What does a Ryūkyū furo look like?
Traditional references describe several features:
- a rounded shoulder;
- a relatively short body;
- long chi-ashi, distinctive projecting feet;
- a stepped transition near the upper rim;
- openings at the front and back in a shape known as kōzama.
Kōzama is an ornamental opening shape also seen in traditional architecture and railings. On this brazier, the openings make the front and back visibly open rather than forming a plain metal wall.
Why is it called a kirikake brazier?
Kirikake describes the way the kettle and brazier fit together. In the traditional Ryūkyū form, the matching kettle sits directly on the brazier.
That is different from a furo where the kettle rests on a separate gotoku.
This distinction helps keep tea vocabulary clear: Ryūkyū names the brazier form; kirikake describes its kettle-support system.
Does the name mean it came from the Ryūkyū Islands?
Possibly, but the historical origin of the name is not certain.
One traditional explanation says the form was made in Ryūkyū. Another links the name to an older Rikkyū-an furo associated with Kitamuki Dōchin, with the pronunciation later changing.
The safest conclusion is simple: tea literature preserves the established name Ryūkyū furo, while more than one explanation survives for how that name began.
Was the early form iron or bronze?
Traditional accounts describe early examples in iron. Bronze versions appeared later, and tea masters developed favoured combinations using them.
References connect Omotesenke's sixth-generation Kōkakusai with a bronze Ryūkyū furo paired with a Taguchi kama. That history does not make the form exclusive to Omotesenke.
How is Ryūkyū furo used in tea?
It belongs to the furo season. Exact timing and combinations can vary by school and practice, so it is better not to give it one universal month.
Which ash forms are used with it?
Urasenke Tankokai teaching material lists Ryūkyū furo among the brazier types suited to marubai oshikiri. Iron Ryūkyū furo also appears with marubai kakiage.
Historical combinations also record nimonji oshikiri. So the named brazier is not locked to only one ash pattern.
Why are round ash forms a natural match?
The brazier has a rounded interior, so a curved ash field follows its shape naturally. That does not turn the relationship into an absolute rule.
What sits under the brazier?
Round shikiita boards are historically associated with Ryūkyū furo in more than one tea lineage. The board is part of the visible arrangement: brazier, board, kettle and ash form are seen together.
Is it still used?
Yes. An Edo Senke report from 2018 describes a Ryūkyū furo in an actual tea gathering and notes its large openings and rounded shoulder.
How is it different from other furo?
Dōan furo: known for its broad open front and normally used with a gotoku.
Mayu furo: known for the eyebrow-like band above its front opening.
Ryūkyū furo: a short, rounded, windowed form traditionally built as a kirikake system with a matching kettle.
Do you need one to make matcha at home?
No. It matters when studying historical brazier forms and the way furo shape, kettle support, board and ash arrangement work together.
The simple answer
Ryūkyū furo is a short, rounded metal kirikake brazier with front-and-back kōzama openings and long feet. Its name is old, but the exact origin of that name remains uncertain.
