Soaking in a warm hot spring in winter is especially blissful! But did you know there’s also “sand bathing” where you soak in sand? If you’re in Kagoshima’s Isa, just a 20-minute walk from the station, there’s a seaside sand steaming hot spring facility called “SunaRaku” that offers this service. Burying your body in black sand heated by hot spring water, with endless ocean views before your eyes, is a unique experience not to be missed when visiting southern Kyushu.

▲%The treatment helps relieve fatigue and invigorate the body.

The sand steaming hot spring in the Isa region of Kagoshima, southern Kyushu, has a history of about 400 years. The large “SunaRaku Hot Spring” uses naturally gushing hot spring water from the coast to steam the sand, reaching temperatures of about 55 degrees. In less than 10 minutes, you can quickly break into a sweat, expelling waste accumulated in the body — an efficiency three to four times higher than regular hot spring soaking. It’s said to help improve conditions such as neuralgia and cold hands and feet.

▲After purchasing a ticket, you’ll receive a yukata. Remember to bring your own towel or purchase a commemorative one at the counter.
After purchasing a ticket, visitors receive a yukata. Remember to bring your own towel. Once changed, you can head to the beachside sand steaming area and wait. The “sand bath” process is quite simple: first, lie flat on the sand, then the staff will start shoveling sand, beginning from your stomach and gradually covering your limbs until your entire body from neck to feet is enveloped in hot spring sand. You can feel the subtle changes as your body transitions from cold to warm to hot over time. With your body immersed in the warm sand and your face caressed by the sea breeze, the cool-above, warm-below sensation is extremely comfortable.

▲%Avoid covering your face and chest with sand. Keep your upper body wrapped in the yukata for comfort.

Fukunaga Naruaki, manager and section chief of SunaRaku Hot Spring, says that if you want to get closer to the coastline, they will assess based on tide and weather conditions. Even if the weather is poor, the sand steaming area under the shelter is unaffected. After the sand bath, rinse your body and then soak in the hot spring pool. If you have more time, you can visit the third-floor observation deck to enjoy the sea view and immerse yourself in a healing journey for the mind, body, and soul.
