About this onsen
Ichinomata Onsen lies deep in the mountains of Toyota-cho, Shimonoseki, Yamaguchi - an area famous for its fireflies - and its water quality earned a place in the '100 Best Onsen of Japan'. Fujino-yu is a day-bathing facility open only on weekends and holidays, opened around 2019 in a converted former inn. The retro interior holds a single indoor bath fed kake-nagashi by an alkaline simple sulfur spring of high pH (28.6°C). Even the showers and wash-station taps run onsen water, and the silky texture is the signature.

More in this area
Nagato-Yumoto Onsen Onto
The source bath of Yamaguchi's oldest hot spring, opened some 600 years ago. Local volunteers rebuilt the aging public bath in 2020; the bathroom sits directly on the spring, so you stand chest-deep in a 1-m pool watching water seep from the bedrock. Around 39°C — made for long soaks. The riverside lounge doubles as a café open to non-bathers. Pair with a stroll through the town redeveloped around Hoshino Resorts' KAI Nagato.
Yuda Onsen Onsen-no-Mori
A large day-spa at Yuda Onsen in Yamaguchi city. The men's 'Byakko-no-yu' faces a Japanese garden while the women's 'Xavier-no-yu' is Western in style; both offer rotenburo, lie-down and jet baths, a walking pool and sauna. The pH 9.2 alkaline water feels silky. ¥1,000 including a face towel, open 10:00–24:00 every day. Upstairs there's a manga and rest lounge plus a canteen. Ten minutes' walk from Yuda-Onsen Station.
Kawatana Onsen Peaceful Seiryūsen
The municipal bathhouse that serves as the source bath of Kawatana Onsen, Shimonoseki's hinterland spa with some 800 years of history — the Mōri lords bathed here. Sodium-potassium chloride water (source about 41 °C) fills the indoor bath, with an open-air tub and sauna; adult admission is a modest ¥480. Family baths (from ¥1,100 for 80 min weekdays / 60 min weekends) and a rest-room package (¥800) allow a leisurely cure-style visit. Open 10:00–21:00 (last entry 20:30); closed the first Thursday of even-numbered months. Kawatana is the birthplace of kawara-soba, noodles grilled on a roof tile — try it after your bath. An easy stop on the way back from Tsunoshima Bridge.
