Nanki-Shirahama Onsen（南紀白浜温泉） is one of Japan’s oldest and most famous seaside hot spring resorts, located in Wakayama Prefecture on the western coast of the Kii Peninsula.

With its blend of coastal beauty and onsen culture, Shirahama is one of those rare places where you can watch the sunset over the ocean while soaking in a steaming outdoor bath.

A Hot Spring Town with Ancient Roots
Shirahama has been famous for its hot springs for over 1,000 years, mentioned even in classical Japanese texts. The mineral-rich water is said to help with muscle pain, skin health, and fatigue.
There are both resort-style hotels with large baths and public outdoor footbaths and hot spring spots scattered along the coastline. Many ryokan and hotels offer ocean-view rotenburo (outdoor baths), making for an unforgettable experience.
Don’t Miss Shirarahama Beach
One of Shirahama’s biggest draws is Shirarahama Beach, a stretch of imported white quartz sand from Australia. It’s especially popular in summer, when visitors can swim, sunbathe, or take evening walks after the heat dies down.
If you’re visiting in cooler months, the beach is still worth seeing and even better when followed by a warm soak at your hotel.
