While wathcing this cool movie called Kwaidan (Jp. 1964) I heard about the great city of Edo. so i looked it up and wow, they had a million people in the 1600s. had to imagine that. anyway this movie is kinda a scary ghost movie (Coco finds it scary Japanese style and doesn't like it, go figure) that occurs in the townhomes of Edo.
this is a picture of Edo circa 1866. of course, this is the ancient name of Tokyo from 1457, when the Edo (now Imperial) Castle was built, to 1868, the end of the Tokugawa shogunate period:
