This museum houses a collection of artifacts from the time of the eruption that were excavated from the areas submerged by the Yamba Dam.[7]
In the areas submerged by the Yamba Dam flooded area, excavation surveys covering approximately one million square meters were carried out over a 26-year period from 1994 to 2019.[2]
Adjacent to the museum, the former Naganohara Daiichi Elementary School building, which was used until 2002, has been relocated and educational materials are on display.[8]
