Otsuchi Town is located along the Pacific coast in eastern Iwate Prefecture and belongs to Kamihei District. Facing the Pacific Ocean to the east, the town extends westward into the Kitakami Mountains, forming a long and narrow geographical shape from the coastline to the inland highlands. Two major rivers, the Otsuchi River and the Kozuchi River, flow from the mountains through the town and empty into Otsuchi Bay, creating a landscape where the sea, rivers, and mountains exist in close proximity. This distinctive geography is a defining feature of life in Otsuchi and has strongly influenced its industries and culture.
Otsuchi Town forms part of the Sanriku region and is included within the Sanriku Geopark, an area recognized for its geological and natural significance. Coastal communities have traditionally depended on fisheries and the bounty of the sea, while inland areas have supported forestry and small-scale agriculture. Although the town suffered catastrophic damage during the Great East Japan Earthquake and tsunami of 2011, it has since pursued recovery and reconstruction with a strong emphasis on disaster preparedness, community resilience, and coexistence with nature.
History
The history of Otsuchi Town dates back thousands of years, with numerous archaeological sites from the Jomon period discovered within the town, indicating early human settlement. During the medieval and early modern periods, Otsuchi developed as an important coastal and administrative center linking inland areas with maritime routes. In the Sengoku period, the area was controlled by the Otsuchi clan, and during the Edo period it came under the direct administration of the Morioka Domain, with the Otsuchi magistrate’s office governing a wide coastal region.
Marine products, especially salmon, played a central role in the town’s prosperity, and Otsuchi flourished as a port town engaged in regional trade. In the modern era, the opening of railways improved transportation and strengthened ties with neighboring cities. On March 11, 2011, the Great East Japan Earthquake and subsequent tsunami devastated the town, claiming many lives and destroying much of the urban area. Since then, extensive reconstruction efforts—including coastal defenses, residential relocation to higher ground, and disaster education—have shaped the town’s renewed identity.
Culture and Traditions
Otsuchi Town’s culture is deeply rooted in its relationship with the sea. Fishing traditions, seasonal festivals, and local performing arts reflect generations of life along the Sanriku coast. One of the most notable traditional performances is the Tiger Dance (Toramai), a dynamic folk dance accompanied by drums and flutes, performed at festivals and ceremonial occasions to pray for safety and prosperity.
Horai Island, located offshore, is said to have inspired the NHK puppet television series “Hyokkori Hyotan Island,” making it a symbolic landmark of the town. The theme song from the program is still used as the daytime chime in the town’s disaster prevention broadcast system. In recent years, cultural activities have also focused on preserving and conveying the memory of the 2011 disaster, with storytelling initiatives and memorial spaces playing an important role in passing lessons on to future generations.
