Yes!! Heard about the museums!
Here's a link if you're like me and have sometimes just wanted to check out what's going on in Tokyo at the moment (shibuya scramble crossing) : https://worldcams.tv/japan/tokyo/shibuya-crossing
It can be nice background for falling asleep and people watching (though who knows if any people will be around really...)
Toward the end of last year, my husband discovered a page full of live web cams similar to the Tokyo one, and his favourite was Jackson Town Square, in Jackson Hole, Wyoming. Every once in a while, I'd say, "How are your people doing in Jackson?" and he'd excitedly click on that tab and check on them. It seemed no matter what time of day or night it was, there was always someone walking by. And, yet, it was never really very busy. Just a weird quiet place. But, yeah... live web cams are interesting.
