Shiroyone Senmaida Rice Fields

Shiroyone Senmaida: A Thousand Rice Terraces Cascading into the Sea of Japan

On the rugged northern coast of the Noto Peninsula in Ishikawa Prefecture, over a thousand tiny rice paddies tumble down a steep hillside toward the crashing waves of the Sea of Japan. This is Shiroyone Senmaida — one of Japan's most breathtaking agricultural landscapes and a living testament to centuries of human perseverance in harmony with nature.

Designated as a National Scenic Beauty (Meisho) and forming a key part of the globally recognized "Noto's Satoyama and Satoumi" agricultural heritage system, Shiroyone Senmaida offers visitors an extraordinary encounter with Japan's rural soul. Here, traditional farming methods have been passed down through generations, and every season paints the terraces in a new palette of colors — from the mirror-like reflections of flooded paddies in spring to the golden harvest glow of autumn.

What Are the Shiroyone Senmaida Rice Terraces?

Shiroyone Senmaida, located in the Shiroyone district of Wajima City, comprises 1,004 individual rice paddies spread across approximately four hectares of steeply sloping terrain. The terraces descend about 50 meters in elevation from the hillside down to the coastline along National Route 249, creating a dramatic staircase of rice fields that appears to pour directly into the ocean.

The average size of each paddy is remarkably small — only about 18 to 20 square meters. Some are as tiny as half a meter square, large enough for just two rice stalks. A beloved folk song from the region captures this charm perfectly, singing of planting 999 paddies only to find the last one hidden beneath the farmer's straw raincoat. The name "Senmaida" itself means "a thousand rice paddies," though some scholars suggest it may also derive from a word meaning "narrow fields."

Because the paddies are so small and the terrain so steep, modern agricultural machinery cannot be used here. Nearly all farming tasks — from preparing the embankments and planting seedlings to weeding and harvesting — are carried out entirely by hand, just as they have been for centuries. This makes Shiroyone Senmaida one of the rare places in Japan where traditional rice cultivation techniques remain a living, working practice rather than a museum exhibit.

A History Shaped by Earth and Sea

The history of Shiroyone Senmaida stretches back approximately 400 years to the early Edo period. After Maeda Toshiie received the Noto domain from Oda Nobunaga in 1581, land reclamation efforts began in earnest. The construction of the Taniyama irrigation canal around 1632 by the engineer Itaya Heishiro — famous for his work on the Tatsumi Canal in Kanazawa — enabled systematic rice cultivation on these slopes.

However, a massive landslide in 1684 destroyed most of the paddies, and much of the land lay fallow for generations. It was not until the Meiji era (late 19th century), when the local salt-making industry declined, that farmers gradually reclaimed and rebuilt the terraced fields. By 1879, the landscape had largely taken on its current form — a remarkable achievement born of generations of patient labor in an unforgiving environment.

The geological character of the area — a landslide-prone zone where steep slopes of quartz porphyry meet the sea — is intimately connected to the terraces themselves. The paddies not only produce rice but also serve a critical function in preventing further landslides by controlling water absorption into the hillside. This dual role as both agricultural land and natural disaster mitigation makes Shiroyone Senmaida a fascinating example of how human cultivation can work in partnership with geological forces.

Why Was It Designated a National Scenic Beauty?

Shiroyone Senmaida was designated as a National Scenic Beauty (Kuni Shitei Meisho) on January 29, 2001, by the Ministry of Education, Culture, Sports, Science and Technology. The designation recognized the site's outstanding value across multiple dimensions.

The geometric patterns formed by the earthen embankments of the paddies create a visually striking landscape that changes character with each season and time of day. When flooded in spring, the terraces become a vast natural mirror reflecting the sky, the sea, and moonlight — a scene that has inspired countless works of art and literature throughout Japanese history.

Beyond its scenic beauty, the designation acknowledged Shiroyone Senmaida's significance as a record of agricultural land development history in the Oku-Noto region, its role in landslide prevention through traditional farming practices, and its preservation of rare agricultural techniques including the "tagoshi" irrigation method, where water flows from one paddy to the next through carefully cut openings in the embankments.

Further recognition came in 2011, when "Noto's Satoyama and Satoumi" — the interconnected landscape of mountain villages, farmland, and coastal communities of which Shiroyone Senmaida is a central feature — was registered as a Globally Important Agricultural Heritage System (GIAHS) by the United Nations Food and Agriculture Organization. This was Japan's first GIAHS designation, underscoring the global significance of the Noto region's traditional approach to living with nature.

Seasonal Highlights and What to See

Every season transforms the terraces into a different spectacle. In late April and early May, water is drawn into the paddies, turning them into shimmering mirrors that reflect the vast Noto sky and the deep blue of the Sea of Japan. The rice planting season, usually around Golden Week in early May, brings volunteers from across the country to help plant Koshihikari rice seedlings by hand — an event visitors can watch or even join.

Summer dresses the terraces in lush, vibrant green as the rice plants grow tall under the long days of sunshine. The contrast between the emerald paddies and the azure sea creates one of the most photogenic scenes on the Noto Peninsula.

Autumn brings the harvest, when the rice turns a brilliant gold and the stalks are hung on traditional drying racks called "haza." The warm tones of the ripened grain against the autumn sky and ocean make this another favorite season for photographers.

In the winter months, the terraces take on a quieter beauty. Since 2011, the annual "Aze no Kirameki" (Twinkling of the Rice Paddies) illumination event has transformed the off-season landscape into a spectacular light display. Approximately 25,000 solar-powered LED lights are placed along the paddy embankments, automatically lighting up at dusk and changing colors — pink, green, gold, and blue — every 15 minutes for four hours. This event earned both the Japan Night View Heritage designation and, in 2012, a Guinness World Record for the largest solar-powered LED display.

The best time to enjoy sunset views is from the Senmaida Pocket Park observation area along Route 249. Arriving about 20 minutes before sunset is recommended to secure a good vantage point and watch the sky gradually set the water-filled paddies ablaze with color.

Recovery After the 2024 Noto Peninsula Earthquake

On January 1, 2024, a powerful earthquake struck the Noto Peninsula, causing significant damage across the region. At Shiroyone Senmaida, approximately 80% of the terraced fields suffered cracks, and the irrigation canal system was heavily damaged. The earthquake was a devastating blow to a landscape that had already survived centuries of natural challenges.

Yet the resilient spirit of the local community prevailed. Restoration work, led primarily by residents and the Shiroyone Senmaida Scenic Preservation Council, began promptly. By spring 2025, around 250 of the 1,000 paddies had been restored sufficiently for rice planting, with volunteers from across Japan joining local farmers to carefully plant Koshihikari seedlings by hand. Recovery efforts continue, and visiting the area is itself considered a meaningful way to support the community's rebuilding.

In recognition of these resilience efforts, Ishikawa Prefecture was selected as one of BBC Travel's "20 Best Places to Travel in 2026," with Shiroyone Senmaida highlighted as a destination where tourism directly supports cultural preservation and community recovery.

Surrounding Attractions

A visit to Shiroyone Senmaida can easily be combined with exploring the wider Noto Peninsula, one of Japan's most unspoiled coastal regions.

The nearby Roadside Station Senmaida Pocket Park, located directly above the terraces along Route 249, offers a restaurant serving local specialties including rice balls made from rice harvested in the terraces, abalone broth udon noodles, and Wajima's famous "Egara Manju" sweets. The park also has a gift shop featuring local produce and crafts. As of recent updates, the Pocket Park operates on weekends (Friday through Sunday).

Wajima City center, about 15 minutes by car to the west, is famous for its morning market (Asaichi) — one of Japan's three great morning markets with over 1,000 years of history. The city is also renowned for Wajima-nuri lacquerware, considered among the finest in Japan, and the Wajima Kiriko Museum, which showcases the towering festival lanterns used in Noto's spectacular summer festivals.

Further along the coast, the dramatic rock formations of the Sosogi Coast, the curtain-like Tarumi Waterfall that drops directly into the sea, and the Window Rock (Mado-iwa) offer additional scenic stops. To the east, the Suzu area features Mitsukejima Island, a striking tree-topped rock formation also known as "Battleship Island."

For those interested in a deeper cultural experience, the Noto region offers opportunities to stay in traditional farmhouse inns, try Noto sake from local breweries, and experience the warmth of rural Japanese hospitality that has made this peninsula a beloved destination for centuries.
