Nagai, the former Yonezawa domain boat transport town that flourished through the Mogami River [Yamagata Prefecture]

Nagai City, located in the southern part of Yamagata Prefecture , was established in 1954 (Showa 29) through the merger of one town and five villages - Nagai Village, Nishine Village, Hirano Village, Isazawa Village, and Toyoda Village - with the former Nagai Town at its center, which developed during the Edo period due to boat transportation on the Mogami River.


Nagai, where Date Masamune was once the lord

The place name "Nagai" means "a place where water gathers," and three rivers, including the Mogami River, flow around the town, irrigating the land

The Nagai Basin, through which the Mogami River flows, has been inhabited since the Jomon period. In the Middle Ages, the district of Okitama was established, and in the Kamakura period, the Nagai clan became the lord and Okitama was renamed Nagainosho. During the Nanboku-cho period, it became the territory of the Date clan, and Date Masamune was also the lord for a time. After the Date clan was exiled to Iwadeyama (Osaki City, Miyagi Prefecture) for disobeying Toyotomi Hideyoshi's orders, it became the territory of the Yonezawa Domain in the Edo period, a status that continued until the Meiji Restoration.


During the Edo period, the Mogami River, which was full of difficult passages, was improved and a dock was established

During the Edo period, a dock on the Mogami River was established in Nagai, making it the center of Mogami shipping in the Yonezawa domain

The Mogami River flows gently up to Oishida (Oishida Town) in the middle reaches, and Oishida thrived as the largest wharf. However, to reach the upper reaches where the Yonezawa domain was located, boats had to overcome many difficult obstacles, making navigation extremely difficult

Hoping to find a way to fix the problem, Nishimura Kyuzaemon, a merchant for the Yonezawa domain, obtained permission from the shogunate and the domain, and began improving the flow of water at his own expense

Construction began in June 1863 (Genroku 6), with excavation of bedrock from Sazawa (Sagae City) to Nagai, and was completed in September of the following year. Wharves were built in Miya and Koide (Nagai City). Since then, Nagai has developed as a town based on shipping on the Mogami River

This continued even after the Meiji Restoration, and continued until the opening of the former Japan National Railways Nagai Line (now the Yamagata Railway Flower Nagai Line) in 1914 (Taisho 3)


Landscapes created by connections with water are registered as cultural landscapes

With the opening of the Nagai Line, Nagai, a town based on water transportation, became a hub for goods transportation in Nishiokitama, primarily by rail, and local specialties such as agricultural produce and silk textiles began to be shipped from Nagai to all parts of the country

Many buildings and structures from that era remain in the center of Nagai, giving a glimpse of the bustle it once enjoyed. Nagai, where many tributaries of the Mogami River converge, is a place where people's lives are based on water, including boat transport, and traces of this can still be seen in the Miya and Koide areas, where there were docks

This unique landscape has been designated as an Important Cultural Landscape by the nation as "Nagai Town Landscape in the Upper Mogami River Basin."
