About location

Aga is best known within Niigata Prefecture for the Agano River valley, a long inland corridor followed by National Route 49. The town extends through steep, forested country in eastern Niigata, where the river flows west towards the Sea of Japan. Route 49 is a principal road between Niigata City and Aizuwakamatsu in Fukushima Prefecture; Akaiwagawa Bridge forms part of this route across a local watercourse. Aga was formed in 2005 through the merger of Tsugawa, Kanose, Mikawa and Kamikawa. In Tsugawa, the Fox Bride Procession is held each May, a local event inspired by a tale of foxes taking human form.

The landscape around Aga is defined by steep, densely forested mountains cut by the Agano River, which has shaped both the town’s linear settlement pattern and local economy. In eastern Niigata Prefecture, Aga spreads across a rural area between the Echigo Mountains and the Aizu region of Fukushima. Tsugawa, the town’s main centre, developed as a river-transport town during the Edo period, when the Agano carried people and goods through this inland corridor. Its older streets retain storehouses and merchant-house character, while the Tsugawa Fox Bride Procession draws on a regional folk tradition.

Region Niigata Prefecture

Shaped by the fertile Echigo Plain and the Shinano River system, Niigata Prefecture developed into one of Japan’s foremost rice-growing regions. Facing the Sea of Japan, it combines a long coast with broad lowlands and mountain country that receives heavy winter snow. Sado Island lies offshore, and its historic gold mines recall centuries of mining that connected the island to Japan’s wider economy. Rice, clear water and winter conditions also underpin Niigata’s respected sake culture and its ski areas. Discover further points of interest through webcams located across Niigata Prefecture.
