It's not a bonsai, but I want you to see it because the autumn leaves were so beautiful. This is a park where old buildings in Tokyo such as samurai residences from the Edo period are preserved.

Maples are commonly used in bonsai. I think it should stay :). I have two maples myself; however, they are a chore in my climate zone because the sun will defoliate them if I don't provide shade.
I've been to Tokyo in the early fall but wish I could've stayed to see the leaves change color. Some day I would like to experience fall and spring in Japan to see the Maples/Sakura trees change.
