As wellness-focused travel increasingly influences holiday planning, onsen destinations across Asia are witnessing a sharp rise in demand. According to digital travel platform Agoda, several Asian cities have emerged as the region’s most popular onsen hotspots, based on activity bookings recorded in January 2026.

Once deeply rooted in Japanese culture, onsens are now a key draw for travellers seeking authentic, local and restorative experiences. From mountain-fed outdoor baths to modern spa towns inspired by Japanese bathing rituals, onsens offer more than just relaxation—they allow travellers to slow down, connect with local traditions and prioritise wellness. Whether you’re travelling solo, with family or planning a mindful escape, these destinations stand out for their immersive hot spring culture.

Here are Asia’s top five onsen destinations in 2026:

1. Osaka, Japan

Topping the list, Osaka blends urban energy with deeply therapeutic onsen experiences. The city’s Osaka Bay Tower offers hot spring baths with sweeping skyline views, making it a favourite for travellers who want relaxation without leaving the city. Visitors can also opt for day trips that combine sightseeing with onsen bathing near Mount Fuji, creating a seamless mix of nature and wellness. Just outside the city lies Arima Onsen, one of Japan’s oldest hot spring towns, famed for its mineral-rich waters and historic charm.

2. Kyoto, Japan

Renowned for its temples, tea houses and timeless streets, Kyoto offers a more tranquil onsen experience, often surrounded by forests and mountains. Kurama Onsen, located in the hills north of the city, is particularly popular for its open-air baths overlooking scenic landscapes. Pairing hot spring indulgence with Kyoto’s cultural heritage—from geisha districts to Zen gardens—makes it a favourite for travellers seeking both relaxation and cultural depth.

3. Ha Long, Vietnam

Beyond Japan, Ha Long has emerged as Asia’s leading destination for Japanese-style onsen experiences. Facilities like Yoko Onsen Quang Hanh Spa recreate the traditional Japanese bathing culture with mineral baths, saunas and relaxation zones. Visitors can enjoy a full-day wellness experience complemented by Japanese cuisine and cultural elements, all set against the dramatic natural beauty Vietnam is known for.

4. Beppu, Japan

Often referred to as Japan’s hot spring capital, Beppu is home to some of the country’s most distinctive geothermal attractions. The famous Beppu Jigoku (Hells)—including Umi Jigoku and Oniishi Jigoku—offer a fascinating glimpse into the region’s volcanic activity. Travellers can take the Beppu Ropeway to Mount Tsurumi for panoramic views before heading to nearby Yufuin, a charming hot spring town dotted with cafés and boutiques. With sound bath meditation, sand baths and diverse onsen styles, Beppu is a complete wellness destination.

5. Nagasaki, Japan

Nagasaki combines onsen culture with rich history and local experiences. Travellers can stay at traditional ryokans that offer hands-on activities such as cooking classes and visits to local farmer’s markets. Ending the day in a ryokan’s hot spring bath provides a deeply calming experience and a closer look at Japanese hospitality, making Nagasaki ideal for travellers who value culture-led relaxation.
