The almost warren-like nature of many parts of Tokyo makes it incredibly easy to get lost, not to mention sidetracked, as it’s often impossible to predict what’s round the next corner.
Not that it’s always something interesting of course. In fact invariably it isn’t. But when it is, photographs and further exploration are usually essential.
For starters from ground level.
And then if possible from above.
Which in this case at least allowed for a real sense of what Tokyo once was, and fortunately in a few places, still is.
