Poster warning of non-working traffic lights, Tokyo area, after earthquake

This is a poster designed by someone who works at a university in Tokyo! I helped a very little! Sleeping things just have a empty bubble in Japanese comics, instead of the ZZZZs we use. Since power cuts are going to continue in the eastern region of the main island of Honshu for the foreseeable future, the traffic lights might not be working. Artist: Yuki Nishimiya
