The area of present-day Nan'yo was part of ancient
Dewa Province. In
Japanese folklore it is the setting of the
Tsuru no Ongaeshi legend. After the start of the
Meiji period, the area was organized into villages within
Higashiokitama District, Yamagata Prefecture with the establishment of the modern municipalities system, including the village of Akayu. Akayu was raised to town status in December 1895. The city of Nan'yo was established on April 1, 1967, by the merger of the former towns of
Miyauchi and
Akayu with the village of Wagō. Akayu is famous for its hot springs, cherries and
hang gliding and includes the former village of
Nakagawa. Miyauchi is famous for its chrysanthemum festival and the
Kumano-taisha Shrine, and includes the former villages of
Urushiyama,
Yoshino, and Kaneyama. The village of Wago was created in 1955 by the merger of the villages of
Okigō and
Ringō. The English travel-writer
Isabella Bird visited Akayu in 1878 and wrote about the town in
Unbeaten Tracks in Japan. The city is named after
Nanyang, China, where according to legend a chrysanthemum spring can make drinkers immortal. ==Government==
