Walking around the Imperial Palace recently, I noticed what look like roma tomatoes growing on a wall. This vine is a famous weed called “crow melon” (カラス・ウリ). Apparently, it gets its name because it provides food for crows. The plants seems as resilient and citified as its avian namesake.
On the same walk, we noticed a boat in the Imperial Palace moat with guys using a small net to pick up leaves. Perhaps the trees above were pruned, and some fell into the moat. The meticulousness of the moat cleaning makes an interesting contrast for the untamed wildness of the crow melon vine and its avian companions.
