About this place

Notes

Yunomoto Onsen on Iki Island, Nagasaki. Discovered approximately 1,700 years ago — legend says the springs bathed a newborn emperor. The high iron content gives the water its reddish colour, and the springs have long been described locally as a bath whose warmth stays with you after you get out. 14 hot spring establishments with sunset views. About 20 minutes by car from Konoura Port. Nearby: ancient burial mounds, shrines, and beaches.

Practical notes

All facilities feature 100% natural flowing spring water. Iron is listed at about 15 times the threshold Japan uses to classify a spring as a ryoyosen, so this is a strongly iron-rich water. With the Yumeguri Pass (1,650 yen), you can visit six locations on the same day. Accessible by ferry from Hakata.
