Kayabuki no Sato, a small hamlet in Kyoto makes sure to keep out any undesired natural disasters through a very unique system.
The hamlet has created small sprinkler systems that cover then entire area in water.
From Spoon & Tamago:
In order to maintain the authenticity of the landscape, officials decided to camouflage all 62 fire sprinklers inside huts. When activated, the huts open up like transformers and sprinklers spray water high into the sky, covering the farmhouses with water.
The system is tested every 6 months and it creates a beautiful spectacle in addition to providing a security and safety measure for protection. Quite a site as the visitors flock to observe the bold measure of maintenance.
