Naganuma Onsen is a hot spring resort located in Naganuma Town, situated in the Sorachi Subprefecture of Hokkaido, Japan's northernmost island. The town itself lies approximately 40 kilometers east of Sapporo, making it accessible for visitors exploring central Hokkaido. The onsen developed as a local bathing destination in the mid-20th century, serving primarily as a community facility for residents of this agricultural region known for its rice production.

The hot springs draw from natural geothermal sources common throughout Hokkaido's volcanic landscape. The mineral-rich waters are classified as sodium chloride springs, with temperatures typically maintained between 40-42 degrees Celsius. These waters are believed to offer therapeutic benefits for muscle fatigue, joint pain, and circulation improvement, though the resort maintains a modest, functional character rather than the elaborate facilities found at major onsen destinations.

Visitors to Naganuma Onsen will find a straightforward bathing experience focused on the natural qualities of the spring water itself. The facilities include gender-separated indoor baths with basic amenities. The surrounding area offers views of Hokkaido's agricultural plains, with the Ishikari River flowing nearby. The onsen operates year-round and provides a quiet alternative to more touristy hot spring resorts, appealing primarily to those seeking an authentic local experience or travelers passing through the Sorachi region.

Access to Naganuma Onsen requires travel to Naganuma Station on the JR Hakodate Main Line, which connects to Sapporo in approximately 35-40 minutes by train. From the station, the onsen is accessible by local bus or taxi, located roughly 3 kilometers from the town center. For those driving, the resort can be reached via Route 234 or nearby expressway exits. Admission fees are typically in the range of ¥400-600 for day-use bathing, reflecting the facility's community-oriented nature.

Best hot spring.

brilliant!

I visited on a weekday afternoon and was surprised to find the parking lot almost full. (Apparently, bathing is free for elderly residents of Naganuma Town.) It's quite a walk from the entrance to the changing room. The heated floors feel great on the soles of your feet. The area from the rest area to the back feels a bit dated, and I feel like the changing room and bath area need some renovation soon. 🥴 There are four indoor baths with different temperatures and one outdoor bath. There were quite a few washing areas. After warming up by soaking in 38, 40, and 42 in order, I returned to 38, feeling so soft and comfortable that I broke out in a sweat. I felt completely refreshed. It would be nice to stay longer, lounging around in the rest area with a manga in hand, then bathing again! There's also a restaurant and shop, so I'd like to enjoy a full day stay next time.♪

It's a good hot spring if it's not crowded. You'll need two 100-yen coins for shoes and a locker. Body soap, rinse-in shampoo, and a hair dryer are provided. Low water pressure in the shower, but a full-body shower is available. The water is directly from the source, so there's no floating debris like at "Yunni no Yu." The changing rooms are cleaned regularly, so there's little hair or debris. However, it gets super crowded on Sunday afternoons. There are few rest areas, so it's difficult to stay in for long periods of time. The hot spring is effective and warms the body sufficiently. It's close to Sapporo, so if you can go on a weekday, it's probably fine.
