Activities

Recognized as a Hokkaido Heritage, Shiraoi’s "Moor Onsen" is a rare hot spring in Japan. Rich in ancient, plant-derived organic compounds, it is often celebrated as a "natural skin toner."

In this activity, we will explore the origins of the hot spring using a geological model, followed by a tasting in specially selected glasses to help you experience the water's remarkable smoothness. Delight your five senses with its unique color, aroma, and touch as you directly take in its nourishing elements. We invite you to a special hot spring cultural experience exclusive to KAI Poroto, where you can deeply immerse yourself in the blessings of the earth.

■ What is "ABCs of Onsen Culture"?

At KAI, a leading brand of hot spring ryocans across Japan, we offer "Onsen Culture Iroha"—a special program designed to help guests go beyond simply soaking in the water and truly immerse themselves in the unique regional hot spring cultures.

This two-day admission ticket is sold exclusively to Hoshino Resorts KAI Poroto guests. You can enjoy all the exhibits and programs in Upopoy before and after checking in and out of Hoshino Resorts KAI Poroto.

KAI Poroto hot spring ryokan inn in Shiraoi, Hokkaido has started offering tours of neighboring Upopoy Park on December 1st, 2023. Upopoy Park showcases Ainu culture as a symbol of coexistence with different ethnic groups. Guests staying at KAI Poroto can take the tour on the day after check-in. You can learn more about local Ainu culture.

Fire is cherished by the Ainu people. While sitting around the fire, enjoy local drinks, snacks, and finger food. We will show a slightly different way to enjoy alcoholic beverages that connects to the spirit of the Ainu culture.

For those wanting to fully enjoy their ryokan stay with a relaxed schedule, we propose ways to spend luxurious, unconstrained time, which is only possible with an extended stay.

Built based on the unique Ainu architecture, “Ketunni”, you can enjoy the 2 types of hot springs, the “Atsu-yu” which is the original hot spring water, and the warm “Nuruyu” that will calm down your body and soul.

In contrast to the open “Sankaku-no-yu” that is located on the lake, the “Maru-no-yu” feels like you are inside a cave. There is a hole on the dome ceiling to connect with the outside, through which gentle sunbeams shine.

We offer highly therapeutic massages by nationally certified staff. After bathing, blood circulation is improved and the body can relax more easily. A massage before dinner also helps with digestion.

Under the supervision of a balneotherapy specialist, KAI presents "Cool-down Soaking"—a unique way to beat the summer heat. Enjoy a revitalizing hot spring experience complemented by specially designed cooling spaces and refreshing beverages.
