Ravine of the summer green which cleared up rare gently

The race by which Japanese like a clear stream and green nationally from ancient times. I'm one who is soon of course, too. A country is small, so the rain which falls will be a valley stream and flow into a sea immediately, and I go to a mountain, so Japan can see a lot of nice valley streams. I think a dream is lucky by a lot of things since the travel which turns around gets those wonderful valley streams for future me.
