Nanyo City and Akyu Onsen: The Hot Spring with Red Source Water Known as the "Onsen to Drink"

Akayu Onsen

Akayu Onsen in Nanyo, Yamagata, is a historic hot spring said to have a history of more than nine hundred years. Several accounts explain its name: one legend holds that it was discovered in the late Heian period by Minamoto no Yoshitsuna, a younger brother of the warrior Yoshiie, while another tells of wounded warriors healing here until the water turned red. The founding date is given differently in different accounts. Known since antiquity as a drinkable hot spring, it lets visitors sample the spring water at a designated fountain.

Tips

Akayu Onsen lies close to Akayu Station where the shinkansen stops, making it an easy base for touring Yamagata. When drinking the spring water, keep to the recommended amount of one or two cups. A trip during the grape and wine season of September and October, combining winery tours with the hot springs, is especially rewarding, and local grape juice and wine make fine souvenirs. Dates for the Eboshiyama cherry festival and other events change from year to year, so check official information before you go.
