Dogo Onsen, one of the oldest hot springs in Japan, is said to have a history of 3,000 years. The Dogo Onsen Honkan, designated as an Important Cultural Property, was originally a three-story building completed in 1894, and has undergone several additions and renovations to its current form. In September 2017, the “Dogo Onsen Annex Asuka-no-Yu” opened, and in July 2024, the Dogo Onsen Main Building will be fully reopened after 5.5 years of repair work, making it even more lively. This walking tour will reveal with a guide the hidden story of this popular hot spring resort that attracts more than 1 million visitors a year, based on the legend, history, and efforts of Dogo Onsen, and how it became the bustling hot spring resort it is today.
