The town of Higashi-Izu sits on the shores of the spectacular Izu peninsula, a wistfully beautiful region that evokes a bygone era. Jutting out into the Pacific Ocean with Mount Fuji as the backdrop, Izu’s volcanic coastline is famous for some of the best onsen and views in Japan.

Try Atagawa Onsen, once chanced upon by 15th-century samurai warrior poet Ōta Dōkan when the waters healed his wounds. Taste local delicacies, such as onsen tamago, where an egg is slowly and gently cooked in its shell in the hot spring waters.

Backed by the snow-capped, pine covered Chūgoku Mountains and facing the sea of Japan, Kaike Onsen can be found on the coast of the San’in Region. Though it’s in a city (Tottori), it promises serene ocean views and a powerful dose of nature’s healing power.

Kaike is a rare saltwater hot spring resort discovered a century ago by a fisherman who saw bubbles rising from beneath the ocean’s surface. Today, people come to harness the restorative powers of the sea for its health benefits and to watch the sunrise over Miho Bay from Kaike Onsen Beach.

One of Japan’s “Three Ancient Springs,” Nanki-Shirahama Onsen has 1,300 years of history and was visited by emperors and empresses during the Asuka period. It remains one of the country’s most popular resorts, with plenty of public onsen for bath-hopping and a beautiful white sandy beach.

The variety of local hot springs includes Saki-no-yu Onsen’s rotenburo, open-air baths built within the rock pools of the Kii Channel (Pacific Ocean).

Here, you can soak in the hot healing waters while gazing at the sea and feeling the refreshing spray of the salty waves crashing onto the rocks.

At the foot of Mount Yufu, Yufuin Onsen offers a bathing experience amid striking and tranquil scenery. It’s a charming, small town with hot springs scattered throughout – many of them outdoors (rotenburo) with a view of the mountain’s twin peaks towering above.

It’s particularly scenic in autumn and winter when mist forms in the valley, rising from the geothermal waters across the rice paddies and beyond.

Be sure to visit Kinrin Lake at the end of the main street – it’s beautiful to stroll around at any time of year, but when the wintery fog descends, the torii gate of the lake’s shrine appears to float majestically on the water.

Stepping foot in Ginzan Onsen feels like traveling back in time to the Taisho period or straight into a scene from Hayao Miyazaki’s Ghibli masterpiece, “Spirited Away.” Nestled in the mountains of Yamagata Prefecture, the town is characterized by its traditional architecture, particularly memorable when winter’s heavy snowfall clings to the rooftops.

Admire the Ginzan River crossed by historic bridges, lined by old wooden ryokans and bathhouses, and illuminated by gas street lamps at night. Check out the one landmark exception, the Shiroganeyu ryokan in the town center that was rebuilt in 2001 by celebrated modern architect Kuma Kengo.

Said to be the oldest hot spring in Japan (another of Japan’s “Three Ancient Springs”), Dogo Onsen is steeped in history, with mentions of it in ancient texts dating back thousands of years. Located in the city of Matsuyama in Ehime Prefecture, the bathhouse building that still stands today was built to honor Emperor Meiji in 1894.

Over the years, it has been frequented by the Imperial Family (there’s still a private entrance for the royal family behind the main entrance). It’s also said to have been the inspiration for the main bathhouse, Aburaya, in “Spirited Away,” with its labyrinth of corridors, stairways, and small tatami rooms.

After a soothing and revitalizing bath, try a “Botchan dango” (a sweet dumpling made from rice flour and tea) and stroll through the pretty, shrine-filled streets in your cotton yukata robe.
