Constructed in the architectural style of the Asuka period, Dogo Onsen Annex Asuka-no-Yu stands as a picturesque symbol of Japan’s oldest hot spring, steeped in the history and legends of visits by Prince Shotoku and the Empress Saimei. Just like Dogo Onsen Honkan, Dogo Onsen Annex Asuka-no-Yu is a hot spring especially beneficial to the skin that flows straight from the source with no reheating or addition of water. The building’s roof is topped with a cupola, a symbol of Dogo Onsen, and in the entrance courtyard is a group of camellia trees known as Tsubaki-no-Mori, recreating a scene from the time when Prince Shotoku visited Dogo Onsen. It is said that at that time he left a stone marker, Yuno-oka-no-hi, on which was inscribed "Around the hot spring of the god, camellia trees grow thick, their branches intertwined. The fruit of the camellias hang low above the water, hiding the fallen petals." Inside are spacious large baths as well as open-air baths, which Dogo Onsen Honkan does not have. There are also two Special private baths that are replicas of the Yūshinden, the bath reserved solely for the Imperial Family at Dogo Onsen Honkan. Here guests can experience bathing in a yucho* bathing robe. Dogo Onsen Annex Asuka-no-Yu also has a spacious 100m² relaxation room and 5 private relaxation rooms where guests can enjoy Dogo Onsen hospitality with tea service.
