Shimobe Onsen — hot springs by indication | Compare & book inns

Overview

Located in Minobu, Yamanashi Prefecture, Shimobe Onsen boasts a history of over 1,200 years. It is most famous for the legend of Takeda Shingen, a powerful warlord who is said to have treated his battle wounds here, earning it the nickname "Shingen's Hidden Spring." Since then, it has been a popular destination for balneotherapy, known for its reputed benefits for injuries and fractures.

The most unique feature of this onsen town is its two distinct spring sources: a lukewarm "nuruyu" (alkaline simple spring) at around 30°C and a hot "atsuyu" (simple sulfur spring) at about 51°C. The local bathing custom involves alternating between the two—acclimating in the nuruyu, warming up in the atsuyu, and then cooling down again in the nuruyu. This unique ritual promotes deep relaxation and helps restore vitality.

Signature Spring Qualities & Benefits

The main "nuruyu" is a gentle alkaline simple spring with very few impurities, making it suitable for drinking to aid digestion. The "atsuyu" is a simple sulfur spring with a faint aroma, which warms the body to its core.

• CutsThe simple thermal springs at Shimobe are known to be gentle and low in irritants. This quality may help soothe the skin and support the natural healing of minor cuts and abrasions, a benefit recognized since ancient times.
• Rheumatoid arthritis
• Sensitivity to coldThe characteristic lukewarm "nuruyu" allows for long, comfortable soaks without stressing the body. This prolonged bathing helps to warm the body deeply and thoroughly, which may alleviate the chronic feeling of coldness.
• Autonomic instabilityThe gentle, lukewarm water allows for extended bathing without over-stimulating the body. This prolonged state of relaxation can help calm the nervous system and may aid in restoring balance to the autonomic functions that regulate stress.
• InsomniaA long, relaxing soak in the lukewarm "nuruyu" can be an effective way to calm the mind and body before sleep. This gentle warming and deep relaxation may help ease the transition into a more restful night's sleep.
• Dry skin

Water Characteristics & Best Season

Shimobe's "nuruyu" is close to body temperature, allowing for long, relaxing soaks without straining the heart. This extended bathing is key to allowing the mineral-rich water to deeply penetrate the body, inducing a state of deep relaxation. Many ryokans offer this water directly from the source (gensen kakenagashi).

While the lukewarm water is especially pleasant in summer, the alternating bath routine makes Shimobe a wonderful year-round destination, as it allows you to warm up thoroughly even in winter. It's an ideal retreat for anyone looking to reset their mind and body.
