Island-hopping in Hokkaido offers an unprecedented healing experience for hot spring enthusiasts. Completely different from the hot spring culture on Honshu, the hot springs on Hokkaido's outer islands carry a pioneering spirit and wild beauty—without meticulously crafted garden landscapes, here you only find the raw power of the purest geothermal energy intertwined with sea breezes.
After experiencing famous hot spring destinations like Noboribetsu and Lake Toya, true connoisseurs are stunned by the unique character of these remote island hot springs. Open-air baths with the aroma of kombu in the sea breeze, winter-only hot spring pools where you can view drifting ice, and secret hot springs known only by fishermen and hot spring artisans—these experiences cannot be found anywhere else in Japan.
Three Distinctive Features of Hokkaido Island-Hopping Hot Springs
Unique Therapeutic Effects of Marine Sulfur Springs
Most hot springs on Hokkaido's outer islands are marine sulfur springs, formed by submarine volcanic activity. Different from inland hot springs, these springs are rich in marine minerals and have significant therapeutic effects on arthritis and skin diseases. The water temperature is generally higher, between 42-45°C, suitable for extended soaking.
Completely Different Bathing Experiences Across Seasons
In spring, you can enjoy the sea breeze in open-air baths surrounded by falling cherry blossoms, while summer brings lavender-scented twilight hours. But the most breathtaking is winter—soaking in falling snow, gazing at drifting ice formations, the silent beauty of heaven and earth as one—this is the ultimate enjoyment only Hokkaido can offer.
Deep Integration of Fishing Port Culture and Hot Springs
Most hot spring ryokans here are operated by generations of fishermen, maintaining humble hospitality. The dinner for the one-night-two-meals package features same-day fresh sea urchins and scallops, paired with local sake—the freshness delivered directly from the fishing boat to the table is unmatched even in Sapporo's city center.

Professional Advice for Hot Spring Enthusiasts
Best Visiting Season
From a hot spring experience perspective, October to March is the best season. The winter open-air bath experience is most breathtaking, but note that some ferries may be suspended due to rough sea conditions. While transportation is more convenient in summer, the therapeutic effects of the hot springs are relatively weaker.
Bathing Etiquette Reminders
Most remote island hot springs are used daily by locals, so please pay special attention to bathing etiquette. Avoid using soap in the hot spring pool, tie up long hair, and do not soak for more than 15 minutes. Some small facilities do not offer towel rentals, so we recommend bringing your own.
Dietary Pairing Suggestions
It is not advisable to drink large amounts of alcohol before or after bathing, but moderate amounts of local sake help improve blood circulation. The local kombu tea served after bathing not only replenishes水分 but also has beauty benefits. We recommend pairing seafood dinners with sake or draft beer.
In recent years, affected by China-Japan diplomatic relations, Chinese tourists have decreased by about 40%. However, this has反而讓這些remote island hot springs return to their peaceful nature. For true hot spring enthusiasts, now is the best time to visit these hidden gems.
