Concept for that tree?
This largest five-storied pagoda is seen at Toji temple, Kyoto. I visited there on a day I heard their cherry trees had bloomed (Last April).
The combination of black tower and pink flowers are so beautiful.
But what is more impressive is, this old Japanese tall tower has an earthquake-proof strength, and the idea of the construction is adopted into newly constructed (extremely modern) Tokyo Sky Tree as well.
