Kuzuryū Onsen Heisei-no-Yu
九頭竜温泉 平成の湯（九頭竜保養の里）
A municipal spa retreat in the mountains at the eastern edge of Ōno, Fukui, close to Lake Kuzuryū. Ringed by the clear Kuzuryū River and forested hills, it offers colourless, soft alkaline simple spring water in an indoor bath and an open-air bath overlooking the valley through fresh greenery, autumn colours and deep snow (the outdoor bath may close on winter weekdays). There are a sauna, a tatami rest hall and a restaurant, and the site forms part of the Kuzuryū Hoyō-no-Sato complex with cottages and the Hotel Flairal Izumi next door. Adults from outside the city pay ¥800 (residents ¥700), children from age 3 ¥400 (¥350). Open 10:00–21:00, from 12:00 on Wednesdays; closed Tuesdays (next day if a holiday) and 1 January. About 17 minutes on foot from Echizen-Shimoyama Station on the JR Etsumi-Hoku Line, or right off the Kuzuryū IC on the Chūbu-Jūkan Expressway. An easy stop after the Kuzuryū roadside station, an autumn drive around the lake or a climb of Mt. Arashima.

Near Lake Kuzuryu — the one hot spring in Fukui's mountain interior
Kuzuryu Onsen Heisei-no-Yu is a municipal day-bath in the Izumi district of Ono, Fukui, on Route 158 as it follows the Kuzuryu River towards the Gifu border. The spring was struck in 1991 — the third year of the Heisei era, hence the name — and the building was fully renovated in October 2014; it stands as a separate block within a complex shared with the Kuzuryu Hotel Flair Izumi and a restaurant. With no other hot spring nearby, it is the precious mountain stop where hikers off Mt Arashima (one of Japan's 100 Famous Mountains) and autumn-leaf or camping visitors to Lake Kuzuryu come to warm up.
A cauldron bath and a fossil rotenburo
Each side has an indoor bath behind a big picture window (main tub around 42°C plus a small jet tub), a roofed open-air rock bath and the signature single-person cast-iron 'Goemon' cauldron. The rim of the rotenburo is set with local ammonite fossils — the Izumi area of Ono is dinosaur-and-fossil country — and you can soak a long time in its gentle 40°C water while gazing at the ridgelines. The cold plunge after the sauna uses raw mountain groundwater and is bracing even in summer. The water is an alkaline simple spring around pH 9.6: thin in minerals, yet clearly slippery on the skin, in the 'beauty-bath' family.
Tips
On weekdays the doors open at 14:00, so arriving straight after a morning hike finds it shut (weekends and holidays open at 10:00). December–March it closes at 20:00; last entry is one hour before closing. Closed Tuesdays and Wednesdays. The baths are not large (about eight wash stations), so weekend evenings in autumn-leaf and summer camping seasons get crowded. The neighbouring restaurant serves meals and the post-bath soft-serve is popular; parking is free. By public transport it is 15 minutes on foot from Echizen-Shimoyama on the JR Kuzuryu Line, but trains run only a few times a day — check the timetable.

Centpia Awara
A city-run day bath in front of Awara-Yunomachi Station, two stops from the Hokuriku shinkansen at Awaraonsen. 'Heaven' and 'Earth' bathrooms alternate weekly between men and women, each with rotenburo and sauna. Chloride water keeps you warm long after. ¥600 and open until 23:00 — a rare walk-in option in a town dominated by ryokan. Try the hot-spring eggs. No tattoos.
Tsuruga Kirameki Onsen Rila Port
Ten minutes by car from Tsuruga, the Hokuriku Shinkansen terminus, a municipal spa on a hill above Tsuruga Bay. Alongside the open-air and indoor baths and sauna there's a swimsuit 'Bade pool' of thermal water, so it's popular with families. Mild simple spring water; a Japanese restaurant and tatami hall for resting afterwards. ¥750 on weekdays, 10:00–22:00, closed Tuesdays — a handy first stop on a Hokuriku trip from Kansai or Nagoya.
Echizen Onsen Isaribi Open-Air Bath
A town-run day spa attached to the Echizen roadside station on the coast famous for Echizen crab. The open-air bath juts toward the Sea of Japan, facing sunsets over the horizon and, after dark, the squid-boat lanterns ('isaribi') that give it its name. Silky 'beauty water', an indoor bath and sauna for a wallet-friendly ¥520. Busy in winter with visitors pairing a soak with a crab lunch.
