The Onsen Experience

For those new to Japanese hot springs, Hanayu Spa Resort offers a perfect introduction to this beloved cultural practice. The facility features both indoor and outdoor baths (rotenburo) filled with mineral-rich natural hot spring water. The outdoor baths are particularly special, allowing you to experience the changing seasons of Japan while soaking in therapeutic waters.

Each bathing area offers various pools with different temperatures and mineral compositions. You’ll find traditional medicinal baths (yakuyu) that change seasonally, offering unique therapeutic benefits. The facility also features an authentic Japanese sauna experience, complete with proper cooling areas for the perfect temperature regulation cycle that Japanese call “totonou.”

One of the facility’s highlights is the ganbanyoku (bedrock bathing) area. This traditional Japanese heating therapy involves lying on warm stone slabs, which can help improve circulation and promote relaxation. The fee is ¥650 on weekdays and ¥750 on weekends, including the special löyly (water vapor) service common in Nordic sauna traditions but adapted for Japanese preferences.

The resort also offers comfortable relaxation areas where you can rest between baths. Professional massage services are available for those seeking extra relaxation, and there’s even a manga (Japanese comic) corner where you can experience this unique aspect of Japanese popular culture.From the massage chair I could see the sheep that are kept at this facility!

No Japanese spa experience would be complete without good food. The resort’s restaurant specializes in two local favorites: handmade udon noodles known for their perfect chewy texture, and shabu-shabu (Japanese hot pot) featuring premium Saitama pork. This is a wonderful opportunity to try authentic Japanese cuisine in a casual setting.
