Is Your Japan Itinerary Too Packed? A Practical Checklist
A Japan itinerary is too packed when it only works if every train connection, meal and attraction goes exactly to plan. The warning sign is not a particular number of cities. It is a day with no room for the journey between the things you want to do.
Start with one ordinary sightseeing day. Add the time you will actually spend leaving your hotel, reaching each place, eating and returning. If the result feels tiring on paper, remove something before you book it.
