Senmaida Rice Terraces — 1,004 Terraces to the Sea

Shiroyone Senmaida (白米千枚田, 'White Rice Thousand Terraces') is a UNESCO World Heritage site comprising 1,004 small rice paddies cascading down steep coastal slopes to the Sea of Japan. Each terrace is tiny (averaging 20 square meters, the smallest traditional rice paddies in Japan), carved into the hillside over centuries by farming families. The geometric pattern of terraces creates a striking landscape — green rice shoots in spring, golden grain in autumn, flooded mirror-like surfaces in winter, and illuminated at night during the winter light display (October–March).

The terraces face northwest toward the sea, creating dramatic sunset scenes where the setting sun reflects in flooded paddies while waves crash against the rocky shore below. The site represents traditional satoyama (里山) agriculture — small-scale, labor-intensive farming integrated with natural landscape. Many terraces are now maintained by volunteers and 'terrace owners' (city dwellers who pay ¥20,000 annually to sponsor a terrace and visit for planting/harvesting), as the original farming families aged without successors. A walking path descends through the terraces, allowing close observation of irrigation channels, stone walls, and the miniature scale of each paddy.
