Most people sprinkling water simultaneously

The most people sprinkling water simultaneously is 288 and was achieved by Midosuji Challenge 2025 (Japan) In Osaka, Osaka, Japan, on 2 August 2025.

The challenged happened at a summer festival hosted at the main street of Osaka-City which is Mido-Suji. The event was organized by a community development group that connects the culture born in Midosuji with the people who live here, and works to help citizens rediscover the charm of Midosuji.

The participants performed Uchimizu which is a traditional Japanese practice of sprinkling water on the ground, typically in front of homes, shops, or along streets. It is commonly done during hot summer days to cool down the surrounding area, settle dust, and create a refreshing atmosphere.
