Toya-onsen Hotel Hanabi

Beside the volcanic shores of Lake Toya in Hokkaido's Shikotsu-Toya National Park, Hotel Hanabi is a four-star ryokan where open-air onsen baths draw directly from the town's geothermal spring line. The lake view from upper floors takes in Nakajima island and, on summer evenings, the nightly fireworks display that gives the property its name.

Guest rooms follow ryokan convention — slippers, yukata, and private bathrooms with deep soaking tubs. A kid-friendly buffet and dedicated children's meals make this a practical choice for families, while the on-site convenience store covers late-night needs without leaving the building.

Toyako Onsen sits roughly two hours by road from Sapporo. The surrounding national park offers caldera hiking trails, and the Volcano Science Museum stands minutes from the front entrance.
