Onsen (Hot Springs)

Luxurious time soaking in hot springs in an elegant hideaway


Nishinoyu (west outdoor bath)

The Unzen area has a very long hot spring history. It is said to have been a destination for its healing waters as long as 1,300 years ago.

Because of Unzen's status as a national park, drilling is prohibited. That means all of the onsen in the area are naturally flowing surface springs. There are 37 source springs of highly acidic alum that contain hydrogen sulfide at a temperature of approximately 90˚C (194˚F), which make them so-called sulfur springs.

The high acidity of sulfur gives the hot spring waters strong antibacterial properties that are effective in treating all kinds of skin conditions including eczema, cuts, pimples, and athlete's foot, and they have beautifying properties that make the skin soft and smooth. They are also beneficial in treating neuralgia, rheumatism, sore muscles, sore joints, chronic digestive ailments, hemorrhoids, and poor circulation. In addition, the waters promote recovery from exhaustion, increase health, and improve one's physical constitution.

The onsen waters promote heat retention, making you feel warm for a long time. It is best NOT to take a hot bath if you are not feeling well or you have serious heart trouble, advanced anemia, breathing problems, or hypersensitive skin/mucous membranes.

The hot spring source is behind our sister establishment, Unzen Miyazaki Ryokan. We have a person in charge of checking the water quality of the baths on a daily basis with a particular focus on maintaining hygiene, so you can relax and use the facilities without concern.

Of course all of the hot spring baths at our establishment and at Unzen Miyazaki Ryokan are naturally flowing surface springs, which means that the water is not circulated. Instead, it flows up naturally from underground and is continually replenished and discarded as it is used, so the water is always fresh.

Hanzuiryo provides an indoor bath at each of the 12 two-story detached private villas. An outdoor and indoor onsen and sauna is attached to two villas (Tsubakien and Juen). Additionally, there are two large onsen baths with outdoor baths and saunas on the east and west sides, to which each villa is connected by an underground passage.

The baths in our 14 villas are only for guests staying overnight. Each bath is quite spacious and provides a genuine onsen experience. The outdoor bath, built with stacked stones, offers an expansive landscape view that changes with the seasons. Hanzuiryo takes great pride in being able to offer this ineffable setting with splendid hot springs as a unique form of hospitality.

Recommended Bathing Techniques

Try not to bathe on an empty or full stomach, but somewhere in between. It is best to avoid bathing after drinking alcohol. Please rinse your entire body first before entering the bath. Especially in cold weather, warm your hands and feet well and enter the bath slowly; entering the bath too quickly can cause the blood pressure to rise sharply and is not good for your health. Persons with weak hearts or weak blood vessels should be especially careful.

At first, limit your bathing time to about 10 minutes, including getting in and out of the hot water. You can extend this time as you become more used to the hot water. Make sure you get out of the bath before your heart starts beating too hard. Drink water after bathing to replenish your fluids, and take a rest.
