Shibuya (2010)

Go Ayano plays Kazunari Mizusawa, a young photographer gathering pictures of girls in Shibuya for a documentary. Suddenly the constant noise of the bustling crowd is drowned out by a high school girl (Aimi Satsukawa) shrieking in anger. Mizusawa is startled, but also confused by the fact that nobody in the area but him seemed to care or even notice. His fascination with figuring out exactly what makes young girls want to come to Shibuya in the first place makes him determined to find out more about her.
