The Hinamizawa Dam Conflict and the sound novel illustration of the dam area are actually based off of the building of the Miboro Dam, which in the end, did result in 4 villages, one temple, and 250 houses being submerged underwater. Two large cherry blossom trees were recovered from the submerged temple and placed in Shirakawa-go, and locals say that in the spring, when the cherry blossoms are blooming, each flower represents a memory of the people from the drowned villages.
Locations in Hinamizawa based on Actual Locations in Shirakawa-goEdit
There are a number of locations featured in Higurashi no Naku Koro ni that are based on real locations within and around the village of Shirakawa-go. A few examples can be seen below.
