Tokyo is a huge city and if I want to point out a certain place, I need a large map. However, here I ask you to satisfy yourself with having a rough idea from this map, where in Tokyo the places taken up by the essays exist.
I also ask your understanding that the information given here might be outdated when you see them, as the oldest pages were written around 2010 and I have not updated them. So, when you read the essays, please bare in mind the date at the end of the page ;-)
