Uchimizu ] refers to the action of sprinkling water on the streets in the summer and has been a tradition in Japan for many many moons. The water keeps the dust low and cools off the immediate area.
The Uchimizukko Daishugo event makes this tradition more interesting by getting loads of maids and cosplayers to do the watering. This years Uchimizu took place recently and marks its 10th anniversary where they managed to lower the air/ground temperature from 34.4°C/38.4°C to 32.4°C/30.2°C by the end of the event.
Fliers for the Uchimizukko event were all over the gaff in Akihabara.
