Yaizu Onsen: Seaside Serenity in a Port Town

A Hidden Treasure Beyond Seafood

Yaizu, a fishing town in Shizuoka famous for its tuna and bonito, holds a secret many travelers don’t expect—Yaizu Onsen. Here, you can savor the best of both worlds: fresh seafood from the harbor and soothing hot springs in the same town. For visitors, it often comes as a delightful surprise: “I never knew Yaizu had such incredible hot springs!”

Healing Waters from 1,500 Meters Below

The hot springs of Yaizu flow from 1,500 meters underground and are among the most mineral-rich in Japan, with an impressive 16g of dissolved components per kilogram. The water has a distinct salty taste, a hint of calcium bitterness, and even a unique aroma from bromine and iodine. Known as a chloride spring, it keeps the body warm long after bathing and is praised for easing fatigue, neuralgia, and cold sensitivity—while also leaving the skin smooth and refreshed.

Ways to Enjoy Yaizu Onsen

Yaizu offers a variety of ways to soak in its hot springs. Stay overnight at a hotel or ryokan with spacious baths, drop by one of the day-use facilities for a quick refresh, or simply rest your feet in a free ashiyu (footbath) while exploring the town. Whether it’s after strolling through a lively fish market or enjoying a seafood feast, the hot springs provide the perfect way to relax and recharge.

An Award-Winning Onsen Experience

Recognized as Japan’s No. 1 in the “Refresh” category of the National Onsen Awards for five consecutive years, Yaizu Onsen has earned its reputation as a true healing destination. Combining the vibrant energy of a port town with the restorative power of hot springs, it offers travelers a uniquely memorable experience. Add Yaizu Onsen to your journey, and discover a side of Yaizu you never knew existed.
