![Kunisaki Shittoi Rush-Woven Coaster Set: Oita’s Rare Igusa Craft [2026]](https://jpmono.com/wp-content/uploads/2026/06/kunisaki-shittoi-rush-woven-coaster-set-where-to-buy-2026-featured.jpg)
On the Kunisaki Peninsula in Oita Prefecture, on the eastern shoulder of Kyushu, a triangular rush called shittoi (七島藺, “seven-island rush”) still grows in terraced fields. It is not the ordinary igusa (藺草) round rush used for most modern tatami. Shittoi is a tougher, three-sided sedge that, splitting into strands when worked, was once the prized fiber for the highest grade of goza floor mats and tatami facing. The coaster and trivet set covered here — hand-woven by the Nanatsumugi workshop — carries that Edo-era material into everyday tableware.
What makes shittoi notable internationally is its scarcity. As synthetic and cheaper imported materials took over the floor-covering trade, shittoi cultivation collapsed across Japan. Today the Kunisaki Peninsula is the only place in the country still growing and hand-weaving it. A coaster woven from this rush is, quite literally, made from a fiber that survives in one district and nowhere else.
This guide is written for international readers comparing natural-fiber Japanese tableware: it covers what shittoi is, how the weave behaves, who the set suits and who should skip it, where the craft comes from, and how to buy it from outside Japan. Note up front that the live product data for this listing is thin — only the Amazon JP listing snapshot is available, and live pricing may have shifted since the writing date.

📖 Glossary — key terms
- Shittoi (七島藺, “seven-island rush”) — a triangular sedge, tougher than ordinary round rush, historically prized for top-grade floor mats. The English name “seven-island rush” derives from its old association with the Tokara/Shichitō islands south of Kyushu.
- Igusa (藺草) — the common round rush used for most modern tatami; softer and far more widely grown than shittoi.
- Goza (茣蓙) — a woven rush floor mat; shittoi was used for the highest grades.
- Tatami (畳) — the traditional Japanese rush-faced floor mat.
- Nabeshiki (鍋敷き) — a trivet; a pad set under a hot pot or kettle to protect the table.
- Rokugō Manzan (六郷満山) — the mountain-Buddhism culture of the Kunisaki Peninsula, expressed in its rock-carved Buddhas and ancient temples.
- Kitsuki domain (杵築藩) — the Edo-period domain on the Kunisaki Peninsula under whose administration shittoi cultivation was introduced and encouraged.

Where this comes from — place, era, and the craft tradition
The Kunisaki Peninsula is a near-circular landmass on the eastern shoulder of Kyushu, in the northern part of Oita Prefecture, reaching out into the Seto Inland Sea. Old volcanic activity centered on Mount Futago left a radial pattern of ridges and steep valleys spreading from the interior toward the coast, so that the farmland here is terraced and small-scale rather than broad and flat. That topography matters: shittoi is a labor-intensive crop tended in modest wet fields, and a landscape of small terraced plots tended by hand is precisely the kind of place where such a crop can persist.
Kunisaki is also one of Japan’s most concentrated landscapes of mountain Buddhism. The peninsula is the heartland of the Rokugō Manzan (六郷満山) culture — a syncretic tradition of mountain temples, pilgrimage routes, and stone carving that took root over a millennium ago. Its rock-carved Buddhas, such as the Kumano Magaibutsu above, and its ancient wooden halls give the region a cultural density unusual for a rural peninsula. The rush craft did not grow up in isolation; it grew up inside this older religious and agricultural landscape.
Shittoi itself entered this landscape in the Edo period. Under the administration of the Kitsuki domain, the triangular rush was introduced and encouraged as a cash crop, and its exceptional toughness made it the fiber of choice for the highest grade of goza mats and tatami facing. For generations it was a premium agricultural product of the peninsula — the rush you wove when you wanted a mat that would outlast ordinary igusa.
- 718 — Rokugō Manzan mountain-Buddhism culture traditionally said to be founded across the Kunisaki Peninsula.
- 12th c. — The Kumano Magaibutsu rock-carved Buddhas attributed to roughly this era (Heian–Kamakura).
- 17th c. (Edo period) — Shittoi introduced and encouraged under the Kitsuki domain; becomes the prized fiber for top-grade goza and tatami facing.
- Early 20th c. — Cultivation widespread across parts of Kyushu as demand for durable rush mats holds.
- Postwar (1950s–60s) — Synthetic materials and cheaper imports displace natural rush; shittoi cultivation collapses nationwide.
- Late 20th–21st c. — The Kunisaki Peninsula becomes the only remaining production area for shittoi in Japan.
- 2026 — Small workshops such as Nanatsumugi continue hand-weaving shittoi into coasters, trivets, and tableware.
Then the market changed. As synthetic flooring and cheaper imported rush spread through the postwar decades, the laborious cultivation of shittoi became uneconomic, and it disappeared region by region. What had been a crop grown across parts of Kyushu narrowed to a single peninsula. Today, the Kunisaki Peninsula is the only place in Japan where shittoi is still grown and hand-woven — a continuity measured not in scale but in survival.
“A shittoi coaster is woven from a rush that, after centuries of cultivation, now survives in exactly one district of Japan — and nowhere else.”
That is the quiet case for the object. Workshops like Nanatsumugi convert the surviving rush into small, useful pieces — coasters and trivets — that keep both the field and the weaving hands at work. Each stalk is split and woven on a hand loom into a firm, dense mat that absorbs moisture and naturally deodorizes, and that shifts over years from fresh green toward a settled amber.

What it does well
Weaknesses and things to verify before buying
- Thin published data. The piece count, exact dimensions, and current price are not confirmed in the source data. Read the live listing carefully before ordering.
- Not waterproof. Rush is absorbent by design; it manages condensation but is not a sealed barrier. A soaked coaster needs to dry fully before storage.
- Hand-care required. This is not a dishwasher or wipe-clean item. Expect to brush off crumbs, wipe lightly, and air-dry to avoid mildew.
- Natural variation. Color, texture, and slight unevenness vary piece to piece. Buyers wanting perfectly uniform, machine-made consistency may be disappointed.
- Heat limits as a trivet. It can serve as a small nabeshiki, but rush will scorch under very hot cast iron; confirm the maker’s heat guidance and avoid direct flame contact.
- International shipping friction. Availability via Amazon JP Global Store, shipping cost, and customs depend on your country; a proxy service may be needed if direct shipping is unavailable.
- Price uncertainty. Because no live price was captured, budget with a margin and verify at checkout rather than assuming a figure.

❓ Frequently Asked Questions
What is shittoi, and how is it different from ordinary igusa rush?
Shittoi (七島藺, “seven-island rush”) is a triangular sedge, distinct from the common round rush called igusa. It is tougher and more fibrous, which historically made it the fiber for the highest grade of goza mats and tatami facing. It is far rarer than igusa — today it is grown and hand-woven only on the Kunisaki Peninsula in Oita.
Are the coasters durable, and how do I care for them?
Shittoi’s toughness gives a firm, hard-wearing weave. Care is simple but manual: brush off crumbs, wipe lightly when needed, and let the piece air-dry fully before storing. It is not dishwasher-safe, and prolonged dampness can cause mildew, so drying matters.
Will the color change over time?
Yes. Like other natural rush, shittoi shifts from a fresh green toward a settled amber over months and years of use. This is considered part of the appeal — a living patina rather than a defect.
Can I use them as trivets for hot pots?
The set is described as a coaster / small trivet (nabeshiki), so light trivet use is intended. However, rush will scorch under very hot cast iron or direct flame, so confirm the maker’s heat guidance and avoid extreme heat.
Does Amazon JP Global Store ship these internationally?
Amazon JP ships many household items internationally via its Global Store, and the listing for this set is the sourced path. Coverage and shipping cost (roughly $15–$40 to the US and EU, higher elsewhere) vary by destination, and customs duties may apply above your local threshold. If direct shipping is unavailable, a proxy service such as Buyee or Tenso can forward it.
Why is shittoi more expensive than standard igusa coasters?
Shittoi cultivation is labor-intensive and now confined to a single peninsula, so supply is small and weaving is done by hand. That scarcity and handwork, rather than a brand premium, account for the higher price relative to mass-produced igusa coasters.
Is the price shown reliable?
No live price was captured in the source data for this listing, so no figure is quoted here as authoritative. Treat any price you see at the retailer as the current one, and verify at checkout before purchasing.
