Ito Hot Spring is famous not only for the quantity of water it produces—the largest in Japan—but also for its rich mineral content, which is particularly beneficial for the skin. The hot spring feeds KAI Ito's public baths, as well as a foot bath and even the guestroom baths.
This outdoor pool is situated beside a Japanese garden and is heated year round to ideal temperatures with waters from Ito Hot Spring. Free pool walking sessions are held on a daily basis.
Guests are invited to relax here after a long soak in Ito Hot Spring's fabled waters. Complimentary locally sourced teas and other regional beverages are offered.
Same day reservations available at the front desk.
Every KAI establishment offers a selection of free activities designed to introduce guests to Japan's regional cultures. At KAI Ito, activities revolve around the camellia, which covers vast swaths of the local area when in season. Depending on the time of year, guests will get to try their hand at coloring various items using a dye made from camellias, or making camellia oil from the seed.
Guests will dye silk cocoons, Shuzen-ji washi paper, and even scarfs and handkerchiefs using a traditional local technique that uses the liquid extracted from Izu's indigenous camellias.
Camellia oil making
During certain times of the year, guests will get the chance to make camellia oil, a popular Izu product that keeps hair and skin moist—perfect to use after a soak in KAI Ito's baths.
