Dōgo Onsen (道後温泉) is the oldest hot spring in Japan, and is located in Matsuyama, in the prefecture of Ehime on the western coast of the island of Shikoku. Filmmaker Brad Kremer created this gorgeous video to show how it began and what it evolved into over the last century -- a great visual buffet of world-building ideas.
