Soak and Soothe: Exploring Japan's Renowned Hot Springs
Japan, with its volcanic origins and abundant natural beauty, is home to some of the world’s most celebrated onsen (hot springs). These healing baths have been a central part of Japanese culture for centuries, offering not only physical relaxation but also spiritual renewal. Whether you’re visiting Japan for the first time or seeking a serene escape, immersing yourself in an onsen is one of the most rejuvenating experiences you can have.

The Healing Power of Japan's Hot Springs
The hot springs in Japan are as diverse as the country itself, with each type of mineral water offering different therapeutic benefits. The effects of the onsen are known to promote both physical and mental well-being, making them the perfect place to unwind after a day of sightseeing or to heal from the stresses of modern life. Here are a few different types (Japan-Guide, 2024):
- Chloride Springs: They are ideal for those seeking relief from muscle pain, fatigue, and even skin conditions. The water is said to have a healing effect on dry skin, leaving your body feeling soft and refreshed.
- Sulfur Springs: Sulfur-rich hot springs are known for their strong therapeutic properties, especially for respiratory conditions. These springs are often found in rural areas and offer a deep, relaxing soak that clears the mind and helps treating acne, diabetes, high blood pressure and joint pain.
- Carbon Dioxide Springs: These bubbly hot springs are famous for their ability to stimulate circulation and relieve stress. The fizzy sensation of the carbonated water provides an invigorating feeling, helping with fatigue and poor circulation.
Popular Hot Spring Areas in Japan
Japan boasts a wide variety of hot spring resorts, with each region offering a unique experience. Here are three must-visit onsen towns for travelers seeking the best of Japanese hot spring culture.
Hakone (Kanagawa Prefecture)

Just a short trip from Tokyo, Hakone is one of the most famous onsen destinations in Japan. Located near the majestic Mount Fuji, this picturesque area is known for its lush forests, scenic views, and luxurious hot spring resorts. Hakone’s hot springs are rich in sulfur. Visitors can enjoy outdoor baths with panoramic views of the surrounding mountains and even enjoy a dip while gazing at Mount Fuji’s snow-capped peak during the winter months (Japan-Guide, 2024).
Kusatsu (Gunma Prefecture)

Located in Gunma Prefecture, Kusatsu is renowned for its hot springs and is considered one of the best onsen towns in Japan. The waters in Kusatsu are rich in sulfur and boast a high mineral content, making them extremely effective for relieving fatigue, improving circulation, and promoting relaxation.One of Kusatsu’s most famous attractions is the Yubatake, or "hot water field," a large wooden structure that channels hot spring water into the town’s public baths. Visitors can also enjoy sulfur steam baths or outdoor baths while taking in the beautiful scenery of the surrounding mountains. Kusatsu is an ideal destination for those seeking a more traditional onsen experience, with its quaint streets and historic charm (Japan National Tourism Organization, n.d.).
Beppu (Oita Prefecture)

Located on the island of Kyushu, Beppu is one of Japan’s largest and most famous onsen resorts. Beppu is home to a variety of hot spring baths, including the famous “Hells of Beppu”—a collection of visually striking hot springs that are too hot for bathing but are open to the public for viewing. The hot springs here are incredibly diverse, offering everything from mud baths to sand baths, and even steam baths (Japan National Tourism Organization, n.d.).For a unique experience, visitors can enjoy the "steam cooking" services, where food is steamed with natural hot spring steam. Beppu’s abundant hot spring waters are also renowned for their therapeutic properties, helping to ease tension and alleviate joint pain (Japan-Guide, 2023).
Hot Spring Etiquette: How to Enjoy the Onsen Experience
While visiting an onsen is a relaxing and therapeutic experience, it’s important to follow some basic etiquette to ensure that you and other visitors enjoy the bath to its fullest (Japan-Guide, 2024).
- Clean Yourself First: Before entering the communal baths, it is customary to clean your body thoroughly at the shower stations. Use a small stool to sit on and wash your body with soap and water. This is a crucial step as onsen baths are for soaking and relaxation, not for washing or rinsing your body.
- Keep Towels Out of the Water: Small towels are typically provided to guests for modesty and practical purposes, but they should never be brought into the onsen. Instead, leave the towel on the side of the bath or on a nearby rack.
- Keep Noise to a Minimum: Onsen are peaceful places for relaxation, so it’s important to keep your voice low and avoid splashing water. Maintain a calm, respectful demeanor while enjoying the bath.
- Tattoo Policy: Some onsen have policies regarding tattoos, as tattoos are historically associated with the yakuza (Japanese organized crime). However, many onsen, especially those in more tourist-friendly areas, are becoming more tattoo-friendly. Always check the onsen’s rules before entering.
