Simply called the Water Hose Festival, the biannual event involves testing the site’s ability to respond to fire. The flammable and historic nature of the structures spurred caretakers to install massive sprinklers and hoses to prevent extensive damage. Each year in December and May, they test the lines and douse the homes, according to the video above that shows a similar process occurring at a site in Miyama. The systems are concealed inside structures that mimic the original architecture, and the new buildings open from the center allowing water to erupt into the air, a spectacular and almost comical process.
