Shukusai "Yushokushomon" no Yado Ishirokan
Shizuoka Prefecture/Shimogamo Onsen100% natural Onsen directly from our private source. Enjoy the fresh, newly born hot spring to your heart's content.
A Ryokan with its own private Onsen source. Enjoy 100% free-flowing natural hot spring water in the large public bath and open-air bath, with no added water or heating. Kaiseki cuisine featuring local ingredients, including splendid alfonsino, is also popular. A recommended place where you can casually enjoy both the Onsen and great dining.
We stayed at “Iroukan” during the Obon holidays. Since we were traveling with our dog, we chose Iroukan based on Reviews while searching for a pet-friendly Accommodation. The hospitality exceeded our expectations—the warmth and smiles from every staff member were truly wonderful. Of course, the food was just as highly rated: incredibly delicious and very generous in portion size.From the moment we arrived at the Accommodation’s parking lot, the staff’s kindness and attentiveness stood out—helping with our luggage, welcoming us at the entrance, and even greeting us with a charmingly retro Showa-era style that surprised us in the best way. Everyone clearly loves dogs, and our dog also seemed completely at ease throughout our three-day stay.The Onsen was also fantastic, with free-flowing natural hot spring water and both indoor and open-air baths to enjoy. It’s hard to sum up in just a few words how memorable the service was—and even the head chef’s unique personality gave us a good laugh.The building has an old-fashioned feel that reflects its history, but it’s exactly what you’d hope for in a classic Ryokan—an excellent place where you can truly relax. There is so much more I’d love to share, but if you’re going to Izu, please stay at Iroukan at least once. It’s absolutely worth experiencing.If we have another chance, this is definitely an Accommodation we would love to stay at again.
はるるのパパ 8/18/2026The staff were incredibly friendly and kind!The Onsen was amazing, but what impressed me most was the hospitality.And the kimbap was unbelievably delicious. On the second day they kindly served inari sushi, but I liked it so much I wanted to eat kimbap two days in a row!!The building is old, but it felt like visiting the countryside, and everything was thoroughly cleaned and spotless.
