This in-depth vlog showcases a stay at Kan no Jigoku Ryokan, a historic hot spring inn deeply nestled in the mountains of Kokonoe, Oita Prefecture, Kyushu. Known for its uniquely named ‘hell of Cold inn,’ Kan no Jigoku Ryokan stands out among Oita’s many celebrated onsen destinations thanks to its renowned cold spring. The inn traces its hot spring heritage back to 1849 in the Edo period, while the ryokan building itself boasts nearly a century of hospitality having been founded in 1928. The author highlights the tranquil, culturally-rich atmosphere, with the lodge offering a total of just 11 rooms for a more private experience.

The central feature of Kan no Jigoku Ryokan is its cold spring, kept at a brisk 13-14°C and continuously flowing at over 2,000 liters per minute directly from the source. It is considered both a sacred spring and an iconic highlight, supported by the addition of a 100-degree sauna in 2023. This combination allows visitors to alternate between the intense heat of the sauna and the invigorating chill of the cold spring—a practice known in Japan as ‘totonoi’—which gives a unique and rejuvenating hot spring experience year-round. The spring’s exceptional water flow and frigid temperature make it especially challenging and rewarding in winter.

Beyond the cold spring and sauna, the ryokan offers two large communal baths and three private baths, some of which use firewood to heat the spring water, lightly infusing the air with sulfur. This variety allows all guests to enjoy the therapeutic benefits of the hot spring, regardless of their preference for traditional bathing or sauna experiences. The property’s secluded mountain setting amplifies the sense of escape and relaxation.

Kan no Jigoku Ryokan also features a seasonally tailored kaiseki dinner, delivering an authentic taste of Japanese regional cuisine and excellent value for guests. With accommodation (including two meals) available from around 30,000 yen per night for two people, the inn is a strong choice for travelers seeking both a cultural and wellness-focused experience off the beaten path in Kyushu. The video includes details not just of the bathing facilities but also offers glimpses into daily life and tips for visiting this lesser-known onsen retreat. Kokonoe is well-known for its scenic highland vistas and is a noteworthy addition to any Oita or Kyushu itinerary.
