Takasugi-an, a tea house in Chino, Nagano Prefecture, Japan. The angle makes this look a little more perilous than it is. But still, you gotta really want some privacy to go up there for a cup of tea.

I love tree houses (but who doesn’t) and look forward to the next Tree Houe Project on the Prairie Garden Trust (next spring I am told). Check out more photos of the tea house.
