Near our apartment is this older house with a deciduous tree that fills out in the summer. I love the bunches of light green pods it produces. Sadly there are not enough old houses or old trees in Tokyo. When you see this combination in Tokyo, it’s at once nostalgic and perhaps futuristic.
Ever resourceful Jason at Flora Grubb Gardens identified it by photo as a Firmiana simplex, Chinese parasol tree in English or aogiri (アオギリ) in Japanese. A quick visit to Wikipedia taught me that it’s an ornamental tree related to cacao. It’s within the same plant family as cotton, okra, hibiscus, and abutilon.
