Shirahama Hot Spring, Wakayama Prefecture | Complete Explanation of the History and Charm of One of Japan’s Three Ancient Hot Springs [2026 Latest Edition]
Shirahama Hot Spring, located in Shirahama Town, Nishi-Muro District, Wakayama Prefecture, is known as one of Japan’s Three Ancient Hot Springs alongside Dogo Hot Spring (Ehime Prefecture) and Arima Hot Spring (Hyogo Prefecture). This historic hot spring, with over 1,300 years of history documented in the Man’yōshū and Nihon Shoki, where Emperor Saimei and Emperor Tenji are recorded to have visited for therapeutic bathing, has developed into one of the Kansai region’s premier hot spring resort destinations, now attracting over 3 million visitors annually.
The greatest appeal of Shirahama Hot Spring lies in enjoying abundant hot springs flowing along the beautiful coastline of Shiraume Beach, comprehensive leisure facilities including Adventure World, and magnificent natural landscapes such as Senjo-jiki and Sandanbeki all at once. The excellent transportation access—approximately 2 hours by express train from Osaka and about 10 minutes by car from Nanki Shirahama Airport—is also a major reason for its popularity among many tourists.
History and Origins of Shirahama Hot Spring
Ancient Hot Spring Continuing from the Man’yōshū Era
The history of Shirahama Hot Spring is as old as the records in the Nihon Shoki documenting that Emperor Saimei and Emperor Tenji visited “Muro-no-Yu” (Muro Hot Spring) in 658, and it is also celebrated in the Man’yōshū as the “ancient hot spring of Muro.” Since ancient times, it was known as a celebrated hot spring that nobles from the capital would travel far distances to visit, and the therapeutic properties of the hot spring and the beauty of the coastal scenery were highly valued.
During the Edo period, it received patronage from the Kishu Tokugawa clan and underwent improvements as a hot spring bathing destination. In particular, “Saki-no-yu” is the oldest hot spring basin continuing from the Man’yōshū era and is still used today; the open-air bath located at the wave-washed shore has become a symbolic landmark of Shirahama Hot Spring.
Development into a Modern Hot Spring Resort
After the Meiji period, as railroad connections improved transportation access, Shirahama Hot Spring rapidly developed as the inner sanctum of the Kansai region. From the 1950s onward, large hotels and traditional inns were constructed one after another, establishing the foundation of the hot spring town.
Currently, seven hot spring sources are scattered along the Yunosaki Peninsula coast, collectively known as “Nanki Shirahama Hot Spring.” While preserving traditional hot spring culture, it continues to evolve as a unique hot spring destination that fuses modern resort facilities.
Spring Quality and Therapeutic Benefits of Shirahama Hot Spring
Characteristics of the Seven Hot Springs
Shirahama Hot Spring has multiple hot spring sources centered on the Yunosaki Peninsula, with the following seven main sources being utilized.
Major Hot Spring Source List:
- Saki-no-yu Source: Sodium-chloride spring, source temperature approximately 60°C
- Shirayuyu Source: Sodium-chloride and bicarbonate spring, source temperature approximately 50°C
- Tsunashirazu Source: Sodium-chloride spring, source temperature approximately 70°C
- Kogaura Source: Sodium-chloride spring, source temperature approximately 55°C
- Kanroku-no-yu Source: Sodium-chloride spring, source temperature approximately 65°C
- Kōyutsu Source: Sodium-chloride spring, source temperature approximately 58°C
- Yunosaki Source: Sodium-chloride spring, source temperature approximately 62°C
These sources are primarily sodium-chloride springs, and due to their proximity to the sea, they are characterized by high salinity. They feature high source temperatures and abundant flow rates.
Therapeutic Benefits of the Hot Spring
Sodium-chloride springs, the primary mineral composition of Shirahama Hot Spring, offer the following therapeutic benefits.
Indicated Conditions:
- Neuralgia, muscle pain, joint pain
- Frozen shoulder, motor paralysis, joint stiffness
- Contusions, sprains, chronic gastrointestinal disorders
- Hemorrhoidal diseases, coldness, post-illness recovery periods
- Fatigue recovery, health improvement
- Cuts and abrasions, burns, chronic skin diseases
- Frail infants, chronic gynecological conditions
Chloride springs are also called “hot springs of heat,” and because salt adheres to the skin after bathing and prevents sweat evaporation, they provide high heat-retention effects and warm the body from its core. Combined with the marine climate, an ideal environment for recuperation and relaxation is established.

Spring Quality and Bathing Etiquette at Shirahama Hot Spring
Bathing Precautions
As Shirahama Hot Spring is a chloride spring, observe the following points.
Before bathing:
- Rinse your body gradually before entering to acclimate
- Avoid bathing after drinking alcohol or eating meals
- Refrain from bathing if in poor health
During bathing:
- Avoid long immersions; limit each bath to approximately 10–15 minutes
- Remember to stay hydrated
- Avoid high-temperature sources; begin with warm water
After bathing:
- As chloride springs offer high heat retention, rinsing with shower water is unnecessary for maximum benefit
- Those with sensitive skin should lightly rinse
- Ensure adequate hydration and rest after bathing
Effective Bathing Methods
Divided bathing:
Multiple shorter bathing sessions are more effective than single long immersions with less physical strain.
Alternating hot and cold bathing:
Alternating between hot spring and cool water enhances circulation. However, be cautious of cardiac strain and consult physical condition before attempting.
Partial bathing:
Beginning with foot baths or half-body immersion offers an alternative when full-body bathing seems difficult.
