Few experiences capture the essence of Japan quite like soaking in an onsen, a traditional hot spring bath naturally heated by the country's abundant geothermal activity. Thanks to Japan's location along the Pacific Ring of Fire, the country is home to more than 27,000 natural hot spring sources and over 3,000 onsen resorts, making hot spring culture an important part of everyday life and travel. From mountain villages surrounded by forests to coastal baths overlooking the sea, every region offers its own unique hot spring experience.

Beyond simply relaxing in warm mineral-rich waters, visiting an onsen is also an opportunity to discover Japan's culture, history, and local traditions. Some hot springs have been welcoming visitors for over a thousand years, while others are famous for spectacular scenery or therapeutic waters believed to help relieve fatigue and muscle aches. If you're planning a trip to Japan, these are some of the best Japanese hot springs worth adding to your itinerary.

Frequently ranked among Japan's top onsen towns, Kusatsu Onsen is famous for producing one of the country's highest natural hot spring water volumes. The town's iconic Yubatake (Hot Water Field) serves as its centrepiece, where steaming mineral water flows through wooden channels to cool before reaching the bathhouses. 

Visitors can also watch the traditional yumomi performance, a centuries-old method of cooling hot spring water without diluting it. So why should you visit? Definitely because this onsen is one of Japan’s highest natural hot spring outputs and its cultural senses.

Spring brings cherry blossoms, autumn offers colourful foliage, and summer provides lush mountain scenery that's equally relaxing.
