Activities

Ito Onsen is a renowned hot spring resort boasting one of the highest water volumes in Japan, alongside Beppu and Yufuin Onsens. This experience allows you to discover the history and water qualities of Ito Onsen where Miura Anjin (William Adams) once spent his time, as well as the hot spring culture of his homeland, England, and Europe. Through an interactive quiz about Ito's abundant spring water volume and a hands-on hot spring drinking experience, you can deeply connect with the unique heritage of this region.

■ 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.

We're excited to announce the "William Adams Deep Dive Tour," a unique opportunity to deeply explore the life of William Adams, the English navigator who became a samurai. This special tour will be held on Mondays through Thursdays, from December 2024 to November 2025. Come and uncover the fascinating story of William Adams!

In order to enjoy the lingering sensation of the hot spring and cool off from the hot water, we offer free drinks and popsicles for when you have finished taking a bath.
For the after bathing drinks, we offer an apple cider vinegar soft drink and IPA beer that sailors drank instead of water during The Age of Discovery. By drinking IPA beer whilst feeling the breeze from the sea from the San Buena Deck, you can enjoy the feeling of being a sailor.

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.

We offer flavored teas made from local tea leaves and herbs along the actual route that William Adams (known as Miura Anjin in Japan) took on his voyage across the seas from England to Japan.

For those who want to fully enjoy both leisurely sightseeing in the surrounding area and a relaxing stay at the accommodation at a great value, we recommend our special consecutive night stay plan.

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.
