Ro

Hearth Setup for the Ro (Sunken Hearth)

In the Japanese tea ceremony, a ro refers to a sunken hearth installed beneath the tatami floor. It is used for heating water during tea gatherings held from early November through the end of April. The ro retains the atmosphere of a traditional hearth used to warm rooms in the colder seasons.

The ro consists of two main parts: the rodan (sunken hearth base) and the robuchi (wooden frame). The standard size commonly used in modern tea rooms is 1 shaku 4 sun (approximately 424 mm) square.

At Sankyodou, we offer consultation for selecting rodan and robuchi when constructing or renovating tea rooms.

Iron Kettle for Ro (Ro-gama)

In tea practice, kettles are selected according to the season: ro kettles for winter and furo kettles for summer. The ro-gama is larger than its summer counterpart and designed for use in the sunken hearth.

In addition to placing it on a trivet (gotoku), the kettle may be suspended from above as part of an elegant presentation.

We also provide professional repair services for kettles, including fixing leaks, chips, and cracks. (Please note: repairs may not be possible depending on the condition of the item.)

Hearth Frame (Robuchi)

The robuchi is a wooden frame placed around the four sides of the ro (sunken hearth), fitted into the tatami. It serves both as a safety feature to prevent heat transfer to the tatami and as a decorative element in the tea room.

There are plain wood (kiji-mono) and lacquered (nurimono) types. Some lacquered robuchi also feature makie (gold/silver powder decoration). Generally, small tea rooms (less than 4.5 tatami) use plain wood frames, while larger tea rooms use lacquered types.

Tea Utensil Shelves — Kōrai-jyoku

Utensil stands for displaying items like mizusashi (water jar) and usuchaki (thin tea containers) are collectively referred to as tana (shelves). There are two main types: movable stands used in the tea procedure area, and fixed shitsuke-dana shelves installed in the tea room itself.

Large movable shelves are called daisu, while smaller ones are called kodana. Shitsuke-dana are typically used in small tea rooms, while daisu and kodana are used in 4.5-tatami or larger tea rooms.

The shelf shown here is a Kōrai-dana(Korean style shelf), a four-legged shelf based on the traditional Kōrai-daisu, but at half the size. It is considered a large kodana and is used with the ro.

At Sankyodou, our experienced staff are available to assist you in choosing the ideal shelf. We also offer repair services for tea furniture.

Thin Tea Containers (Usuchaki)

While thick tea (koicha) is stored in ceramic jars (cha-ire), usuchaki for thin tea are usually made of lacquerware or other materials. The most common type is the natsume, named after its resemblance to the jujube fruit.

Other types include nakatsugi(completely cylindrical caddies), fubuki, and Kinrinji containers. We offer a wide selection of usuchaki to suit your preferences and tea style.

Thick Tea Containers (Cha-ire)

The cha-ire is a ceramic container used for holding matcha for thick tea (koicha). It is often accompanied by a colorful shifuku, a silk pouch that acts like a kimono for the container, adding a layer of aesthetic and cultural depth to its presentation.

Water Jar (Mizusashi)
– Yellow Kochi ware, Hanamaru Pattern

A mizusashi is a container used to hold fresh water for replenishing the kettle or rinsing tea utensils like the tea bowl and a whisk. Mizusashi are made from various materials including ceramics, metals, and woodwork, and come in a wide variety of shapes and styles.
