The Danbata (terraced fields) of Yusumiura is a highly distinctive agricultural landscape located in the Nanyo region of Uwajima City, Ehime Prefecture. These fields, formed by stacking small stones on steep mountain slopes, create a unique stepped structure that has earned them the nickname 'The Pyramids of the Uwajima Sea.' Beyond their visual beauty, these fields are recognized as a 'National Important Cultural Landscape,' representing the profound wisdom and resilience of people who have lived in harmony with this rugged natural environment.
The history of these terraced fields dates back to the Edo period. Legend has it that the third lord of the Uwajima Clan allowed local residents to freely cultivate the mountains in exchange for mandatory sardine fishing. During the Meiji era, as sericulture (silk own farming) flourished, more stone walls were constructed to cultivate mulberry trees for silkworms. In the past, these fields were also vital for growing sweet potatoes and wheat. Today, the preservation of this precious landscape is actively supported by the NPO 'Danbata wo Mamorou-kai' (Society to Protect the Danbata).
The most striking feature is the dramatic contrast between the stone walls cascading toward the sea and the lush fields between them. Built on slopes with an average gradient of 40 degrees, the stone steps reaching over 1 meter in height are truly awe-inspiring. As one of the 'Shikoku 88 Scenic Views,' the site allows visitors to enjoy both a historical rural landscape and the brilliant blue of the Uwajima Sea simultaneously. The scenery changes beautifully with each season, offering new discoveries every time you visit.
From April to May, the region enters the harvest season for potatoes. During this time, the 'Furusato Dandan Festival' is held, where you can experience the lively atmosphere of the first potato harvest. In August and September, the area sometimes hosts the 'Danbata Light-up' event, where bamboo and candles create a mystical, illuminated scene amidst the quiet night, offering a truly magical experience.
At the base of the fields, 'Dandan Chaya' offers delicious local cuisine made with fresh, locally sourced vegetables and seafood. It is a perfect place to relax and enjoy the bounty of nature. Additionally, the shop 'Dandan-ya' sells local specialties, including 'Danju'—an original shochu made from potatoes harvested right from these terraced fields. It is a wonderful spot to touch the local food culture.
The area surrounding the Danbata is filled with the rich nature of Uwajim. You can find facilities for fishing and staying in traditional fisherman's lodgings (Fisherman Minshuku) to fully experience the gifts of the sea and mountains. The area is also near spots related to the Shikoku 88 Temple Pilgrimage, making it a part of the historic pilgrimage routes.
Because the area around the terraced fields is steep, it is highly recommended to wear comfortable walking shoes. Since some paths can be unstable, sneakers or trekking shoes are most suitable.
