Guida
Warabi no Tanada is a stunning collection of rice terraces located on the northern slope of Mt. Hachiman in Aichi Town, Karatsu City, Saga Prefecture. Spanning an elevation from 180m to 420m, approximately 1,050 rice paddies spread out in a magnificent fan shape across a 240m vertical range. This landscape is highly acclaimed and has been officially recognized as one of 'Japan's 100 Best Rice Terraces' by the Ministry of Agriculture, Forestry and Fisheries, as well as a 'Japan's 100 Best Walking Paths' by the Yomiuri Shimbun. It is also designated as a 'Important Cultural Landscape' of Japan. The 'Nozurazumi' stone walls, constructed using natural basalt stones, create a powerful and rugged aesthetic reminiscent of ancient mountain castles, leaving visitors in awe.
The history of these terraces dates back centuries, with the structure likely established during the mid-to-late Edo period. Since the Meiji era, the scale of the cultivation has expanded through land reclamation. The sophisticated water management system, which utilizes tributaries of the Ohira River and 'Yokomizo' (horizontal grooves) channels crossing the mountain slopes, has been vital for maintaining the terraces over many generations. The preservation of these stone walls has been supported by 'Ishigaki To-ryo' (master stonemasons) and community-based mutual aid organizations known as 'Tema-ko,' ensuring that this traditional landscape survives into the modern era.
The most striking feature is the interplay between the massive stone walls and the terraced fields, particularly in the Minamigawara district. Visitors can also observe advanced hydraulic engineering, such as the water flowing between paddies and the hidden drainage systems (ankyo) designed to suit the terrain. The surrounding area is a lush 'Satoyama' landscape with forests of oak, cedar, and bamboo. For a panoramic view, the observation deck at the Tanada Exchange Plaza offers the perfect vantage point to see the entire expanse of the fields.
The scenery changes dramatically with the seasons. In late March to early April, yellow rapeseed flowers bloom, signaling the arrival of spring. From late May, the rice-planting season begins, creating a beautiful mirror effect where the sky is reflected in the water-filled paddies. Summer brings deep greenery, while late September features the vibrant colors of red spider lilies. In late February, local events like the 'Rice Terrace and Cherry Blossom Village' may occur, making the cherry blossom season another wonderful time to visit. Daytime is ideal for photography, as the sunlight enhances the reflections in the water and the textures of the stone walls.
This area is a hub for nature-based activities. Local community programs often include 'Rice Terrace Walking' tours, attracting many visitors from urban areas. Depending on the season, you may find opportunities for agricultural experiences or hiking through seasonal flower-filled fields. It serves as an educational site for learning about the relationship between nature and traditional farming, offering much more than just a visual experience.
The 'Tanada Exchange Plaza' is located near the terraces and provides essential amenities such as parking, restrooms, and a local produce shop. The area is part of a natural park near Mt. Hachiman. It is located approximately 5km from central Karatsu and 5km south of central Aichi Town, making it an excellent stop during a sightseeing trip through Karatsu.
As the area includes steep slopes and unpaved paths, sturdy walking shoes (sneakers or trekking shoes) are essential. Please be mindful of local residents and avoid entering restricted areas where farming is in progress. Since local shops may only accept cash, please carry Japanese Yen for any small purchases.
