The most rewarding big city on earth for people who like to wander.
This is a shape, not a schedule. Each day has two anchors and a lot of slack, because 3-day itineraries that book four things a day fall apart the first time lunch runs long. Move things around freely — the neighbourhoods are grouped so that walking between stops actually works.
Tokyo rewards splitting up. Restaurants seat parties of two to four easily and groups of eight barely at all, so plan to break apart for meals and meet at a station. A shared plan with everyone's picks on it saves the endless 'where are you now' texting.
