Awazu Onsen claims to have been founded by the shugendō monk Taichō in the Nara period under the command of the mountain deity Hakusan Daigongen. Taichō was a native of neighbouring Echizen Province and is said to have been the first person to have claimed Mount Hakusan, from which the hot springs at Awazu Onsen have their source. Although it is a small resort with few more than ten ryokan, each inn has its own well, rather than using a common source.
The Hōshi Ryokan within the area, founded in 718 AD was for some time recognized by the Guinness Book of World Records as the world's oldest hot spring inn, but the title has since been taken by Nishiyama Onsen Keiunkan, founded in 705.[1]
