Hot Spring

Mornings waking up to the sound of waves, wrapped in the morning sun.
Magical nights where moonlight illuminates the sea.
You can savor every moment with the warmth of the water in your room’s open-air bath.
Atagawa Onsen boasts abundant water volume and high spring temperature.
You can enjoy its blessings as many times as you like, whenever you like.

Atagawa Onsen is said to have been discovered by Ota Dokan, the warlord who built Edo Castle.

The origin of Atagawa Onsen dates back to when he found steam rising thickly from the ground in a field
and named it “Atagawa” (Hot River).

Later, in 1931, the excavation of a self-gushing source was successful,
and it reached its peak during the group travel boom in the post-war high economic growth period.
Even today, it boasts the highest number of towers per site area in Japan with 13 towers,
and continues to heal the bodies and minds of travelers as a “Showa Hot Spring Town”
utilizing its abundant water volume.

In the private open-air baths equipped in all rooms, you can enjoy the free-flowing hot spring water of Atagawa Onsen, which boasts an abundant volume.

The unique design of each room is another characteristic of IZU RETREAT.
In the “Former Grand Bath Suite,” where the former large public bath has been converted into a guest room, we offer a spacious open-air bath of about 20 sqm just as it was back then. There are also rooms where you can enjoy a private sauna along with the open-air bath.

All open-air baths offer an unobstructed panoramic view of the sea of Higashi-Izu from every room.

Our free room service offers a “Tea Bath” experience. You can enjoy drinks and light snacks while soaking in the open-air bath equipped in every room.
Please indulge in a luxurious sensory experience: gazing at the horizon where the sea and sky merge, listening to the sound of the tide, and tasting the flavors of Izu.
