Take a look at the movie too. Walking along the river was a little bit like walking along the seashore today. This is at the lower sidewalk, the upper sidewalk is okay.
It was extremely strange weather in Tokyo yesterday with this freak sandstorm, apparently blown over from China. These photos show the sky in my neighborhood on what was a bright, sunny day until the sand blew over. In addition to huge winds, I don’t think it was particularly safe. Most people wore masks but it still irritated eyes.
I hope it clears up today.
