Like mkjr, my old Kodansha Tokyo City Atlas served me well over the years. The new version from 2012 (3rd ed.) is available on Amazon as well. The only electronics I use are my cameras and my laptop, which I connect to the hotel wi-fi to check and send e-mail and work on photos. My phone gets turned off when I board the plane in the states and stays off until I return home. Smart phone, GPS, meh!
