Planning your stay
Tokyo is huge, but you do not need to see everything. Choose one main area to stay in (for example Shinjuku, Shibuya or Asakusa) and plan a few key sights each day. Leave some free time for exploring side streets, cafés and parks.
Make sure you know how to reach your accommodation from the airport or main station before you arrive. Screenshots of maps and hotel details are helpful when Wi-Fi is slow or you are tired after a long flight.
