One of my favorite Youtube channels is Rambalac. It's just videos of walking through various places in Japan, from crowded streets to peaceful natural areas. No voiceover or explanations - almost every video is as if a video camera were moving around on its own and recording everything it saw (occasionally he interacts with things). Super relaxing to have on in the background, and really cool to watch to get a glimpse of everyday life there.
