Oita Prefecture in northern Kyushu is Japan’s onsen capital by volume — producing more hot spring water than any other region on earth. Two towns define its identity: Beppu, a sprawling resort city of steam vents and industrial-scale bathing facilities, and Yufuin, a quieter highland village of boutique hotels, art galleries, and scenic mountain views.
Beppu: Japan’s Onsen Capital
Beppu produces over 130,000 kilolitres of hot spring water daily from approximately 2,800 springs — more than any other city in the world except Yellowstone. Steam rises from vents in pavements, gutters, and hillsides throughout the city, giving Beppu a perpetually misty, slightly surreal atmosphere. The city has eight distinct hot spring zones (Beppu hatto) with different mineral compositions: bicarbonate waters for skin; sulphur waters for respiratory issues; iron-bearing acidic waters with distinctive reddish colours.
Beppu’s Eight Hells (Jigoku)
The Beppu Jigoku (“Hells”) are eight ornamental hot springs that are too hot to bathe in (95-99°C) and instead function as sightseeing attractions. Umi Jigoku (“Sea Hell”) is a vivid cobalt blue pool coloured by dissolved magnesium; Chi no Ike Jigoku (“Blood Pond Hell”) is rust-red from dissolved iron oxide; Tatsumaki Jigoku (“Waterspout Hell”) erupts regularly like a geyser. A combined ticket (¥2,200) covers seven of the eight hells. Eggs and puddings cooked in the spring steam are sold at each site. The jigoku cluster in two groups — Kannawa and Shibaseki — connected by city bus.
Beppu Bathing Culture
Beyond the jigoku, Beppu has dozens of public bathhouses (hyotan onsen, takegawara onsen) ranging from elegantly tiled Meiji-era facilities to neighbourhood community baths charging 100-200 yen. Takegawara Onsen, a distinctive wooden hall built in 1879, offers both regular hot spring bathing and sunayu (sand bath) — being buried to the neck in geothermally heated black sand while attendants shovel and pat. The experience lasts 10-15 minutes and produces a profound sense of warmth and relaxation. Hyotan Onsen has 15 different baths including outdoor pools, steam baths, and a waterfall bath.
Yufuin: Refined Mountain Onsen Village
Yufuin, 30 minutes inland by bus from Beppu, sits in a highland basin at the foot of Mount Yufu (1,583 m) — a dormant volcano that frames the village in every view. While Beppu is an industrial-scale resort, Yufuin developed as a boutique destination: small, high-end ryokan and kashikiri buro (private bath) inns, art museums, and an elegant main street of craft shops and cafes. The misty lake Kinrin-ko in the village centre steams visibly in cool mornings as warm spring water meets cold air — one of Japan’s most photogenic natural morning scenes.
Yufuin Art & Culture
Yufuin has an unusually high concentration of small art museums for a village of 12,000 people. Yufuin Floral Village (English cottage-style shopping area), the Yufuin Film Festival (held annually in August since 1976 — one of Japan’s most beloved independent film events), and the Yufuin Music Festival give the village cultural depth beyond bathing. The Yufuin no Mori train from Hakata (Fukuoka) is itself a designed experience — a forest-green wood-panelled luxury train passing through Oita’s green valleys.
Getting There & Practical Tips
Beppu: from Fukuoka (Hakata) by Sonic Limited Express (2 hrs, ¥5,250) or by bus (2.5 hrs, ¥3,000). From Osaka by overnight ferry (Sunflower Ferry, 11 hrs). Yufuin: 30 minutes from Beppu by Yufu Express train or bus. The Yufuin no Mori scenic train runs 3 times daily from Hakata (2 hrs). Best seasons: autumn and winter, when cooler temperatures make outdoor bathing most pleasurable and morning mist most atmospheric. Yufuin’s main street becomes very crowded on weekends and during Golden Week; weekday visits are strongly recommended.
