The best-known nature in Agano City is Lake Hyoko, a marsh registered under the Ramsar Convention. You can feast your eyes on lotus flowers in summer at the lake. Mt. Gozu, crowded with mountain climbers throughout the year, spans the border between Agano City and Aga Town.

The history of Agano City changed drastically due to the War of Otate that broke out after Kenshin Uesugi died. After Uesugi was stationed in Aizu, Agano went under the direct control of the Shogun and a magistrate's office was established. In the Meiji period, Suibara was the center of the prefectural administration for some time.

Gozu Hot Spring Resort, consisting of three hot springs, Deyu, Imaita and Murasugi, has been loved by many people since the old days as the hot spring of Niigata Prefecture for medical treatment. The hot water that springs out on the majestic land surrounded by pine trees and cedar trees at the mountain foot has a wonderful healing effect. There are hot springs open for day trips too where you will always be welcomed.
