As waves of cold fronts hit, warm and cozy hot springs have become a top choice for travelers. Hidden hot springs, often nestled in serene forests and mountains, offer tranquility away from the hustle and bustle. Coupled with their therapeutic properties, these hidden gems are considered one of Japan’s treasures. For this reason, tourism operators have released a list of Japan’s “Top Five Ultimate Therapeutic Hidden Hot Springs,” carefully curated for hot spring enthusiasts.

●ComeExperience 300-year-old Takuhyu Spring at the Eel Soup Inn
“Takuhyu” is ranked as Miyagi Prefecture’s most beloved hidden hot spring. Known as the “Eel Soup” since 300 years ago due to its association with Japanese eels, this hot spring, though highly alkaline, is rich in sodium bicarbonate sulfate with sulfur powder. This sulfate spring has a toner-like effect, helping to improve eczema and enhance skin beauty, making it a top choice for women.

● The Longevity Spring Hidden in Iwai Onsen
Iwai Onsen Ryokan in Tottori Prefecture is known as the area’s oldest inn. Both the bath water and shower water here come directly from the source. One of its famous features is the “Longevity Spring,” where the water level can rise above chest height. Additionally, the open-air bath “Suishaan,” surrounded by bamboo fences and available for free private reservation, is also extremely popular.

● Shoji no Yu: Relaxation and Healing
Located among the mountains of Okushita, “Shoji no Yu” is famed for its strongly alkaline medicinal hot spring. Its thick, milky water not only beautifies the skin but also relieves fatigue and treats conditions such as frozen shoulder, arthritis, poor blood circulation, and chronic digestive diseases. Soaking in the open-air bath while gazing at the beautiful mountain scenery of Okushita makes it a favorite among visitors.
