Yaizu Onsen Shizuoka is a therapeutic hot spring facility in Yaizu, a major Pacific Ocean fishing port city in central Shizuoka Prefecture, Japan, one of the country's leading centers for bonito and tuna fishing whose port handles hundreds of millions of dollars of seafood annually. The chloride-sodium thermal waters of Yaizu are characterized by their saline mineral richness, prized in Japanese balneological tradition for deeply warming the body, improving blood circulation, and leaving skin soft and moisturized. After exploring Yaizu's vibrant fish market and seafood restaurants, soaking in the warming chloride spring waters provides the perfect restorative complement to a day spent by the Pacific in one of Shizuoka's most authentically maritime communities.

Insider tip — Yaizu Onsen is rooted in one of Japan's leading tuna fishing ports on Suruga Bay, where sodium-chloride thermal waters are tapped from coastal sediment layers beneath the harbour district. The brine-heavy water is intensely warming and fishermen have long used these baths to recover from cold overnight voyages. The port fish market operates from early morning and a post-market soak here forms a perfect local itinerary.
