Part of Onneyu Onsen's Story
Since 1899

Oe Honke's history is closely connected with the early development of Onneyu Onsen.

In 1899, when the area was still remote and difficult to reach, the founder of Oe Honke obtained permission to use hot-spring water on the left bank of the Muka River. This marked the beginning of the hotel.

In those early years, travel to the region was not easy and visitors were few. As transportation improved and the town developed, Onneyu Onsen gradually became a destination known for its natural hot springs.

Oe Honke grew alongside the community. Over the generations, buildings and facilities have changed, but natural hot-spring bathing has remained central to the hotel's identity.

Our tradition is not simply about how long the hotel has existed.

It is about continuing to care for the hot springs and welcoming today's travelers to enjoy them.

Experience Hokkaido's Four Seasons from an Open-Air Bath

Oe Honke's open-air baths, or rotenburo (露天風呂), are set beside the Muka River. Surrounded by natural stone, the baths offer views of the changing landscape and an opportunity to enjoy Hokkaido's fresh outdoor air.

The indoor bathing area also includes different types of baths, such as a reclining bath and a whirlpool bath. Choose a comfortable bathing temperature and enjoy the experience at your own pace.

Everything You Need to Know Before Your First Onsen Visit

Japanese hot springs have a few simple customs that help everyone enjoy the baths comfortably. If this is your first time, a little preparation is all you need.

• Wash before entering the bath. Use the shower and washing area, and rinse thoroughly before getting into the water.
• Traditional communal bathing is without swimwear. Oe Honke has separate shared bathing areas for men and women.
• Keep towels and hair out of the bathwater. Tie up long hair and leave your bathing towel outside the pool.
• Respect other guests' privacy. Do not take photographs or use your phone in the changing or bathing areas.
• Walk carefully. Mineral-rich hot-spring water may make some surfaces slippery.

Bathing Hours for Overnight Guests

The public baths are closed between 1:00 AM and 4:30 AM. Guests staying consecutive nights may use the hot springs from 2:00 PM on subsequent days. Hours may change temporarily due to maintenance or operational reasons.

Shampoo, conditioner, body wash, hair dryers and selected toiletries are available in the bathing facilities.
