I am always amazed at how fast and tall hydrangea grow in Tokyo. The ample rain and warm weather makes them shoot up out of nowhere. I like how this huge cluster on a Tokyo boulevard effectively hides the ugly utility box. This space between the sidewalk and wide street is usually planted with ginkos and azaleas by the local government. Like the hollyhocks down the street, these hydrangea were probably planted by a neighbor and then reappear each year on their own.
