[Renewal opening on December 16, 2021!] Mie Castle Hot Spring/Shimanin no Yu (inside Loisir Hotel Naha)


Mie-jo Onsen Shimanno-Yu at Loisir Hotel Naha is one of the few natural hot springs in Okinawa.

It opened after successful trial excavation in Heisei 1 November. A hot spring with a temperature of 40.9 degrees is self-boiling from 800 meters underground, and the spring quality is sodium iodine and chloride springs. Fossil seawater from about 8 million years ago was heated by geothermal heat, and the ingredients are completely different from the volcanic hot springs that are common on the mainland. Since it is fossil seawater, it contains salt, and is characterized by being salty when licked, and is generally called a salt spring. Unlike volcanic hot springs, it is odorless and can be used in a normal bathing mood. After bathing, the salt that adheres to the skin prevents sweat from evaporating, and the heat retention effect is excellent. It is popular as a “warm hot spring” that is friendly to women. Please enjoy a relaxing time by incorporating the blessings of natural hot springs born from the sea of Okinawa into your mind and body
