Some patches of cemetery
These pictures were shooted by a skyscraper in Roppongi, one of biggest entertainment districts in the middle of Tokyo.
Careful looking of the above picture makes you find some graveyards or cemetery, surrounded by modern buildings.
Some patches of graveyards exist in the middle of Tokyo because some small temples are there still now. (Most of them are not allowed to enter for people who don't have their ancestor's grave.)
