But it's just the word "Up." Like climbing UP a tree. How hard could it be?
Because the Japanese do not speak English? "Up" is only used to mean a closeup shot. You think that would make sense for a flying house?
Climbing up a tree is Nobo-ru 登る
Flying is To-bu 飛ぶ
Jumping is To-bu 跳ぶ
There is no one word for it.
