Above is a photo of a Nakano sidewalk on a busy boulevard. Between pedestrians and the street is an organized planted green strip with railing, ginko trees and azalea bushes. In May, seemingly out of nowhere, giant pink hollyhocks have appeared. What is amazing is that they extend over 1 kilometer on the sunny north side of the boulevard. Someone must have planted a few, which then went viral.
Below is a sidewalk and street in Odaiba, with corporate planting on the left and public planting on the right. Despite the greater green quotient, this Odaiba sidewalk is generally lacking in street traffic, pedestrian traffic and any un-planned greenery. There is something dead and sad about these streets, where large convention centers, a few offices and shopping malls are interspersed with empty lots.
