More than a thousand wind chimes and a splash of water define this matsuri (Japanese festival) right in front of Tokyo Station.
The main things to see are the wind chimes lined up and the annual Marunouchi de Uchimizu, where water is thrown onto the sidewalks using traditional buckets to cool down the street. Along with those events, there will be stalls selling popular types of kakigori (shaved ice). These events take place along Gyoko-Dori Avenue.
The Marunouchi de Uchimizu event takes place on July 28 from 5 p.m. to 6:30 p.m. You have to register on the day of the event to participate, but viewing is free. The wind chimes will be displayed from 9 a.m. on July 28.
