If one plans on a walking tour of Tokyo, a map _might_ be of some use. Did wander about some nice areas before giving in to subway usage. Went through a nice big wooded park. Quite peaceful aside from the heavy metal band performing at the open stadium. Odd sight, seeing a bunch of 30something mothers with their kids there. Cute in a twisted way to see wee little ones imitating the "devil's horn" symbol. Singer had zero charisma, and the usual nonsence bad sound.
