Discovered, as legend tells, through a divine message from Sumiyoshi Daimyojin, Onto is a sacred hot spring with a 600-year history and the oldest onsen in Yamaguchi. Cherished by the local community for centuries, it remains the spiritual heart of Nagato Yumoto.

What makes Onto unique is its spring water, which rises directly from beneath the bath itself. Without any heating, dilution, or exposure to air, the water retains its natural purity—allowing you to experience an exceptionally fresh, “born-at-the-source” hot spring.

As you sink into the warm water, its gentle texture and long-standing cultural presence quietly convey the timeless connection between the onsen and the people who have bathed here for generations.

Gathering place for
locals and travelers
Instagram Location

POPPA was once the liveliest snack bar in Nagato Yumoto Onsen. Preserving the original interior and the same name, it has been re-imagined with today’s sensibility as a place for new encounters, run together with the team at SOIL Nagatoyumoto and special guest hosts. Locals, people working in the onsen town, and travelers who happen to stop by along the way. People of different ages and backgrounds sit side by side at the same counter, and before they know it, conversations begin to flow. That quiet comfort of a night that starts with “Nice to meet you”—that’s POPPA. Open on an irregular basis from early evening into the night. Each gathering takes on its own shape, guided by who shows up and how the evening unfolds. What happens is part of the surprise. That sense of openness is at the heart of POPPA.

Hours: Around 19:00 – 24:00 (irregular schedule)
