Oshu City is located in the southern inland area of Iwate Prefecture and is the second most populous municipality in the prefecture after Morioka City. It serves as the central city of the Tango region and has long developed as an important administrative, economic, and cultural hub. The city lies in the southern part of the Kitakami Basin, bordered by the Ou Mountains to the west and the Kitakami Highlands to the east, with the Kitakami River flowing north to south through its center. The extensive Isawa alluvial fan and surrounding mountainous terrain have supported agriculture and human settlement since ancient times.
Oshu City was established in 2006 through the merger of Mizusawa City, Esashi City, Maesawa Town, Isawa Town, and Koromogawa Village. Today, it functions as the seat of the Southern Iwate Regional Promotion Bureau and is characterized by a well-balanced industrial structure that integrates agriculture, manufacturing, and commerce. The city is widely known for its premium agricultural products such as Maesawa Beef, as well as its rich historical heritage and convenient transportation infrastructure.
History
The area that now forms Oshu City has played a central role in the history of northeastern Japan since ancient times. Archaeological sites such as the Isawa Castle Ruins and the Tsunotsuka Tumulus testify to its importance during the early development of the region, particularly during conflicts between the imperial court and the Emishi people. In the Heian period, the Tango area became a strategic base for the Northern Fujiwara clan, supporting the prosperity of the Hiraizumi cultural sphere as an economic and production center.
During the early modern period, the area was governed by the Sendai Domain, where castle towns and post stations such as Mizusawa and Iwayado flourished through commerce and river transport. With the modernization of transportation networks in the Meiji era and beyond, Oshu strengthened its industrial and logistical foundations. The municipal merger in 2006 marked the beginning of the modern city of Oshu, which continues to preserve its layered historical legacy across its districts.
Culture and Traditions
Oshu City’s cultural identity is shaped by a combination of rural traditions and a long continuum of historical heritage rooted in the Tango region. Traditional festivals such as the Hidaka Fire Prevention Festival reflect community-based beliefs tied to daily life and disaster prevention. Folk performing arts, including Onikenbai and Shishiodori (deer dance), have been carefully preserved and passed down through generations as expressions of local spirituality and communal bonds.
The city is also renowned for producing prominent historical figures such as Choei Takano, Shinpei Goto, and Makoto Saito, whose legacies are preserved in museums and historic residences. In addition, traditional crafts such as Nambu ironware and Iwayado tansu cabinetry remain integral to the city’s cultural and industrial landscape, connecting everyday life with craftsmanship refined over centuries.
