An architect friend tipped me off to a community garden on a riverbank in Tsukishima. The local government has organized each small section of the concrete retaining wall into individual plots where residents are tending their gardens. It is a great use of dead space, and allows people in a crowded neighborhood to have outdoor plants.
Most of the plots have a simple, double bench structure to hold potted plants. A few have removed the benches and filled the plot with soil. Most are growing flowers, one is dedicated entirely to bonzai.
I wonder if more small parks and un-used spaces can be turned into community gardens. The overall effect displays both individuality and community.
