9 Hidden Hot Springs of Fukui Prefecture — From Sea Cliffs to Mountain Gorges in Hokuriku

Fukui Prefecture offers a striking contrast between the rugged coastline of Echizen facing the Sea of Japan and the deep mountain valleys of Oku-Echizen stretching toward the Hakusan range. While neighboring Ishikawa and Toyama may boast greater numbers of hot springs, Fukui's thermal waters each possess a distinct character. A radon spring inn standing on the shores of the Mikata Five Lakes, a mountain retreat rebuilt by community determination after an avalanche, a 7-room auberge transformed from a Meiji-era shipping house — Fukui's hot springs reflect the stories of both the land and its people. Here are nine of the most distinctive selections.

1. Kogashima Onsen Kogashimaso (Wakasa Town, Mikatakaminaka District)

Kogashima Onsen Kogashimaso is a secluded single-inn hot spring nestled on the shores of Lake Suigetsu, one of the Mikata Five Lakes in Wakasa Town, Fukui Prefecture. As a member of the Japan Association of Secluded Hot Spring Inns (Nihon Hitou wo Mamoru Kai), this inn features a charming atmosphere created by a relocated 150-year-old traditional farmhouse. The inn's name 'Kogashima' derives from a nearby mountain. Passing through the impressive thatched-roof gate, guests are greeted by a panoramic view of Lake Suigetsu. The spring water is classified as simple weak radioactive cold mineral spring (radon spring), with a source temperature of approximately 13-15 degrees Celsius, heated for bathing use. The men's bath includes a small free-flowing source water tub where guests can enjoy the colorless, transparent radon spring in its natural state. The outdoor baths offer views of the tranquil lake and surrounding mountains, with the autumn foliage season being particularly spectacular.

2. Hatogayu Onsen (Ono City)

Hatogayu Onsen is a secluded single-inn hot spring nestled along the Uchinami River gorge at approximately 538 meters elevation in the deep mountains of Ono City, Fukui Prefecture. The spring was discovered during the Kaei era (1848-1854) when an injured dove was observed healing its wounds in the waters, giving the inn its name meaning 'Dove's Bath.' A member of the Japan Association of Secluded Hot Spring Inns (Nihon Hitou wo Mamoru Kai), the inn was completely destroyed by an avalanche in February 2018 but was magnificently rebuilt in 2021 with strong local support. The spring water is classified as sodium-chloride and bicarbonate cold mineral spring with a source temperature of approximately 14.2 degrees Celsius, heated for bathing. The colorless, transparent water has a gentle feel on the skin and is said to be effective for neuralgia, muscle pain, and poor circulation. Surrounded by the rich nature of Hakusan National Park, the area is particularly beautiful during fresh green and autumn foliage seasons. The inn is also known for its mountain cuisine featuring river fish such as char and yamame trout, with mountain vegetables in spring and mushrooms in autumn. Although closed during winter due to heavy snowfall, guests can fully enjoy the tranquil atmosphere of this hidden hot spring during the operating season.

3. Takasu Onsen Kokumin Shukusha Takasuso (Fukui City)

Takasu Onsen Kokumin Shukusha Takasuso is a national lodge perched on a hilltop overlooking Takasu Beach on the northern coast of Fukui City. Its greatest attraction is the spectacular outdoor bath commanding panoramic views of the Sea of Japan, where guests can enjoy the extraordinary luxury of bathing while watching the sunset sink below the horizon. The spring water is alkaline simple hot spring (pH 9.24) with a source temperature of approximately 49 degrees Celsius. The 100% free-flowing source water is renowned for its silky smooth feel, often called 'Beauty Bath' as it leaves the skin remarkably soft after bathing. The facility was renovated in 2019, combining clean modern amenities with the affordable pricing characteristic of national lodges. The cuisine featuring fresh seafood from the Echizen coast is also highly regarded, with the winter Echizen crab dishes being particularly exceptional. Its convenient location along the Echizen coastal drive makes it an easy stop for visitors exploring the area.

Practical Guide — What to Know Before Visiting Fukui's Hot Springs

Fukui Prefecture's hot springs can be efficiently explored by dividing them into four areas.

Awara Onsen and Mikuni Area: Echizen Awara Onsen Tsuruya, Awara Onsen Grandia Housen, and Mikuni Onsen Bouyourou are located in the northern part of Fukui Prefecture. Tsuruya and Grandia Housen are situated in the Awara hot spring district, approximately 15 minutes by car from Kanazu IC on the Hokuriku Expressway. Tsuruya is a historic sukiya-style ryokan founded in 1884, featuring 100% free-flowing water from three private hot spring sources. Grandia Housen is one of Hokuriku's premier large-scale resorts with 111 rooms, boasting panoramic views from its "Heavenly SPA" observatory bath. Mikuni Onsen Bouyourou is an exclusive 7-room auberge-style ryokan near Mikuni Port and Tojinbo, completely rebuilt in 2021 into a modern space where guests can savor the finest Echizen crab cuisine, including imperially presented crabs. The two Awara hot spring inns are within walking distance of each other, with Mikuni Onsen Bouyourou about 15 minutes away by car. During the Echizen crab season (November to March), visitors can enjoy a luxurious combination of hot springs and premium crab.

Echizen Coast and Fukui City Area: Takasu Onsen Takasuso and Sano Onsen Fukunoyu are located in this area. Takasuso sits along the Sea of Japan coast in northern Fukui City, offering spectacular sunset views from its clifftop outdoor baths. It takes about 40 minutes by car from central Fukui City. Sano Onsen Fukunoyu is located on the outskirts of Fukui City and pairs well with an Echizen coast drive as a convenient day-trip hot spring facility. Winter coincides with the peak Echizen crab season, allowing visitors to enjoy both hot springs and crab.

Oku-Echizen Mountain Area: Hatogayu Onsen and Kuzuryu Onsen Heisei-no-Yu are situated in the mountainous interior of Ono City. Hatogayu Onsen lies at the gateway to Hakusan National Park, tucked away along the Uchinami River gorge off National Route 158. Due to winter closure (early December to late April), visits are limited to May through November. Kuzuryu Onsen Heisei-no-Yu is near Lake Kuzuryu and unusually accessible for a hidden hot spring, being within walking distance of Kuzuryu-ko Station, the terminus of the JR Etsumi-Hoku Line. Both facilities are connected via National Route 158 and can be visited in a single day from Ono IC. Combining the trip with sightseeing at Echizen-Ono Castle and Lake Kuzuryu makes for a fulfilling journey.

Wakasa and Reinan Area: Kogashima Onsen Kogashimaso and Hanahasu Onsen Somayama are located in the Reinan region of southern Fukui. Kogashimaso is a member of the Japan Association of Secluded Hot Spring Inns, standing on the shores of Lake Suigetsu, one of the Mikata Five Lakes, and features a relocated 150-year-old traditional farmhouse. The trip can be combined with the Rainbow Line scenic drive and the Wakasa Jomon Museum. Hanahasu Onsen Somayama is conveniently located just 10 minutes from Imajo IC on the Hokuriku Expressway, with parking for 200 vehicles, making it an ideal roadside stop. In July, the surrounding lotus fields come into bloom, offering a unique combination of lotus viewing and hot spring bathing.

Overall, a rental car is recommended for exploring Fukui's hot springs. The Awara Onsen area is well-served by public transport, with shuttle buses and pickup services available from JR Awara Onsen Station (a Hokuriku Shinkansen stop). Takasuso is accessible by bus from JR Fukui Station (about 50 minutes) and Kuzuryu Onsen is within walking distance of JR Kuzuryu-ko Station (about 15 minutes), but bus service to other locations is limited. National Route 305 along the Echizen coast may be closed due to rough seas in winter, so check road conditions in advance. The Oku-Echizen area receives heavy snowfall in winter, making snow tires essential.
