1. Dogo Onsen, Shikoku Island 

Situated on the smallest of Japan’s major islands, Shikoku Island, Dogo Onsen is supposedly the oldest in Japan. Dating back 3,000 years, it’s frequented by millions of tourists and Japanese citizens every year. 

Despite its central location, its beautiful architecture and fascinating history make it a must-see. Resembling a Japanese castle, the main bathhouse in Dogo Onsen is crafted out of wood and was constructed in the 19th Century. Within it, there are two main bathing areas, known as the Tama-no-Yu and the Kami-no-Yu with four bathing packages to choose from.

2. Kusatsu Onsen, Gunma 

Located within Gunma, a mountainous and incredibly picturesque prefecture on Japan’s Honshu Island, Kusatsu Onsen is one of the most renowned in the area. A popular tourist destination, it’s beloved due to its ancient bathing rituals and powerful hot springs. People have also said that the springs can even cure illnesses – perhaps the reason why so many visit it each year.

Within Kusatsu, you’ll be able to wander around and enjoy a handful of different hot springs for free. If you want to stay overnight, you can select from several resorts or a night in a traditional Ryokan.

3. Fuji Kawaguchiko Onsen, Yamanashi Prefecture

If you’ve always wanted to witness the almighty Mount Fuji, then there’s no better place to do so then Fuji Kawaguchiko Onsen in Yamanashi Prefecture. Located 3 hours southwest of Tokyo, this breathtaking natural hot spring is situated at the base of the mountain. Within the Onsen, there are numerous Ryokan inns and guesthouses, each with their own indoor and outdoor bathing options. 

One of the most picturesque Onsens, it’s awe-inspiring to visit in spring when all of the cherry blossom trees bloom throughout the area. Whether you visit it alone, with friends or with your partner, you’re guaranteed to have an unforgettable experience.
