Former Matsunami Castle Garden

Former Matsunami Castle Garden: A Hidden Karesansui Masterpiece on the Noto Peninsula

Near the rugged northern tip of Japan's Noto Peninsula, on a wooded hill overlooking the Sea of Japan, lies one of the most unusual dry-landscape gardens ever discovered in the country. The Former Matsunami Castle Garden (Kyū-Matsunami-jō Teien) is not a manicured tourist attraction nor a temple courtyard raked daily by monks. It is an archaeological garden — a fragile fragment of late-medieval Japan, frozen beneath the soil for nearly five centuries until investigators began to coax it back into the light. Designated a National Place of Scenic Beauty in 2012, the garden stands as a rare witness to how Kyoto's refined courtly aesthetic traveled to one of the most remote corners of the country and there evolved into something entirely its own.

A Castle on the Edge of the Sea

Matsunami Castle was built atop a low hill along the left bank of the Matsunami River, which empties into the Sea of Japan in present-day Noto-chō, Ishikawa Prefecture. The castle is traditionally said to have been founded in 1474 by Hatakeyama Yoshichi, the third son of Hatakeyama Yoshimune — the powerful warlord who served as military governor (shugo) of Noto Province. From its windswept ridge, the Matsunami Hatakeyama line ruled the Oku-Noto region for roughly a century, governing six successive generations and serving as a key satellite of the family's principal fortress at Nanao Castle to the south.

The castle's story ended abruptly in 1577. After the great daimyo Uesugi Kenshin captured Nanao Castle, his retainer Nagasawa Mitsukuni led an army against Matsunami. The sixth and final lord, Matsunami Yoshichika, took his own life as the castle fell, and the site was abandoned. What no one realized at the time was that the fire that consumed the castle had also sealed something extraordinary just beneath the surface — and that this sudden, complete destruction would, paradoxically, become the reason a Muromachi-period garden could survive almost intact into our own century.

Rediscovery After Four Centuries

The garden was first noticed in 1962, when local investigations turned up unusual stone arrangements on the southeastern slope of the castle hill. Decades of careful, intermittent fieldwork followed, and a comprehensive excavation began in 2016. What emerged was remarkable. On a flat terrace roughly 600 square meters in area, about 15 meters above sea level, archaeologists uncovered the remains of a small pavilion (azumaya) together with an attached building, and — running just beyond the pavilion's eaves — the ruins of a karesansui dry-landscape stream nearly nine meters long.

Because the castle had burned and been abandoned in a single short campaign rather than evolving gradually over centuries, the garden was effectively sealed where it lay. Many famous Japanese gardens have been re-laid, repaired and re-imagined many times over the generations. Here, by contrast, the original Muromachi design has been preserved very close to its first form. In recognition of this unusual completeness and the garden's distinctive design, the Agency for Cultural Affairs designated the site a National Place of Scenic Beauty (meishō) on January 24, 2012, with additional area added to the designation in September 2023.

What Makes the Design So Unusual

Most karesansui gardens that visitors know — the bright white sand of Ryōan-ji or the rippled gravel of Daisen-in — use raked sand or fine gravel to suggest flowing or still water. The Matsunami garden does something quite different and, as far as scholars know, almost unique. Its stream is built not of sand but of small, flat, round river pebbles, deliberately set on edge in a technique called kobadate. The result is a textured, almost three-dimensional ribbon of stone running between nineteen carefully placed landscape stones (keiseki) of varying sizes.

The detail is almost choreographic. At the spring head, the pebbles are arranged in a tight spiral around a small central stone, evoking water bubbling up from between rocks. As the stream descends, the pebbles set on edge mimic the rushing current of a mountain brook, while in the curves and eddies behind the larger stones they are laid flat to suggest pooling, calmer water. Whirls, ripples, lingering eddies and quickening rapids — all are conjured from arrangements of stone alone, with a sensitivity that historians of garden art consider without parallel among surviving medieval Japanese gardens.

From Kyoto to the Wild Noto Coast

How did such sophisticated garden art arrive at the very edge of the Sea of Japan? The clue lies in the Matsunami family's unusual connections. Although they ruled a remote province, they served as retainers (hikan) of the Hino family — one of the most influential aristocratic houses in late-medieval Kyoto. This relationship gave members of the clan reason to spend extended periods in the capital, where they would have seen, and quite possibly helped to commission, the kind of refined viewing gardens then being built for nobility and Zen abbots.

Yet the garden at Matsunami is not simply a Kyoto garden transplanted to the provinces. The pebbles used in the stream are local Noto stone, and the kobadate edge-set technique appears nowhere else in the surviving canon. The Matsunami designers seem to have absorbed the philosophy of the capital — the idea that a garden should be a contemplative, idealized landscape viewed from a building — and then reinvented its execution using the materials at hand. The result is a vivid example of cultural transmission and local creativity unfolding together.

Visiting the Garden Today

Visitors should know that the Former Matsunami Castle Garden is not a typical sightseeing destination with daily opening hours. To protect the fragile archaeological remains, the garden site itself is not regularly open to the public. Ongoing investigation and conservation work continues, and visits to the garden ruins require advance arrangement with the Noto-chō Board of Education, ideally at least two weeks before the planned date. Access may also be suspended due to weather, fieldwork, or preservation conditions, so flexibility is essential.

The wider Matsunami Castle Park (Matsunami-jōshi-kōen), however, is freely accessible. Walking trails lead through the castle's earthworks, past the remains of moats, baileys and ramparts, and on a clear day the view extends across the river mouth to the open sea. The former Matsunami Station, closed when the Noto Railway line was discontinued, has been repurposed as the Matsunami Castle Information Center, with displays on the castle's history and the discoveries that came to light beneath its grounds.

Please note that since the Noto Peninsula earthquake of January 2024, parts of the region are still recovering. Visitors are encouraged to check the latest local information before traveling and to support local communities during their visit.

Beyond the Castle: Exploring Oku-Noto

A visit to the Matsunami garden is best combined with the rich attractions of the surrounding Oku-Noto region. Just a short walk from the castle, Matsunami Sake Brewery has been producing local sake since the Edo period and welcomes visitors. Down the coast, the dramatic silhouette of Mitsukejima — popularly nicknamed "Battleship Island" — rises from the sea, while the Koiji Coast nearby is famous for a poignant local love legend and is now considered a destination for couples.

For those interested in deeper time, the Mawaki Archaeological Site preserves a Jōmon-period settlement dating back roughly six thousand years, complete with a museum and an associated hot spring. Tsukumo Bay, with its hundred-fold inlets carved into a rugged ria coastline, offers some of the most distinctive seaside scenery in all of western Japan. Together they make Oku-Noto a surprisingly layered destination — equal parts archaeology, history, and unspoiled coast.
