Warubano no Tanada is a stunning collection of rice terraces located on the northern slope of Mt. Yahata in Aichi Town, Karatsu City, Saga Prefecture. Spanning an elevation from 180m to 420m with a vertical drop of approximately 240m, about 1,050 rice paddies spread out in a beautiful fan shape. This landscape is highly acclaimed and officially recognized as one of 'Japan's 100 Best Rice Terraces' by the Ministry of Agriculture, Forestry and Fisheries, as well as one of the '100 Best Walking Paths in Japan' by the Yomiuri Shimbun. It is also designated as an Important Cultural Landscape. The most striking feature is the 'Nozura-zumi' (natural stone stacking) technique used for the walls; the powerful, rugged texture of the basalt stone walls evokes the feeling of an ancient mountain castle, leaving visitors in awe.
The history of these terraces is ancient, with the structure believed to have existed since at least the mid-to-late Edo period. Since the Meiji era, land reclamation expanded the scale of the rice paddies. The water management system is highly sophisticated, utilizing a complex network of irrigation ponds fed by tributaries of the Ohira River and 'Yokomizo' (horizontal grooves) that traverse the mountain slopes. The maintenance of these stone walls has been preserved through generations by 'Ishigaki Toryo' (master stonemasons) and the 'Tema-ko'—a community-based mutual aid system of local residents. This combination of traditional craftsmanship and community spirit has protected this beautiful landscape for centuries.
The primary attraction is the dramatic interplay between the massive stone walls and the terraced fields. The walls in the Minamigawara area are particularly distinctive and impressive. Visitors can also observe advanced ancient water management techniques, such as the way water flows between the paddies and the use of underground channels (ankyo) adapted to the terrain. The surrounding area is lush with forests of oak, cedar, and bamboo, offering a serene Satoyama (traditional rural landscape) atmosphere. A dedicated observation point at the Tanada Exchange Plaza provides a perfect vantage point to overlook the vast, sweeping expanse of the terraces.
The appearance of Warubano no Tanada changes completely with each season. In late March to early April, you can see bright yellow rapeseed flowers blooming, signaling the arrival of spring. From late May, the rice planting season begins, creating a stunning mirror effect where the blue sky reflects perfectly in the water-filled paddies. In summer, the greenery becomes deep and lush, while in late September, the fields are adorned with red spider lilies. Additionally, events like the 'Tanada and Sakura Village Project' occur in late February, making the cherry blossom season another enchanting time to visit. For photography, daytime is ideal as the sunlight highlights the textures of the stone walls and the water reflections.
This area is a hub for connecting with nature. Local community programs often host 'Tanada Walking' tours, attracting many visitors from urban areas. Depending on the season, you might encounter agricultural experiences or hiking through flower fields created on fallow land. The area serves as an educational site for learning about the relationship between nature and traditional farming, offering more than just a visual experience—it is a deep dive into Japanese rural culture.
Near the terraces, you will find the 'Tanada Exchange Plaza,' which is equipped with parking spaces, restrooms, and a local farm shop. The area is part of a designated natural park near Mt. Yahata. It is located approximately 5km from the center of Karatsu City and 5km south of the center of Aichi Town, making it an excellent stop during a sightseeing tour of the Karatsu region.
As the area includes steep slopes and unpaved paths, sturdy walking shoes (such as sneakers or trekking shoes) are essential. This is especially important if you plan to walk around the observation points. Since this is an active agricultural area, please be respectful of the farmers and avoid entering restricted areas or stepping on crops. Please note that cash is required for purchases at local farm shops or nearby stalls, so it is best to carry Japanese Yen with you.
