Straight answers
Common Tokyo timing questions
Is spring or autumn automatically best for Tokyo?
Not automatically. Both can offer comfortable historical normals, but exact holidays, weekends, and published events can make one available week more practical than another.
Does the score predict Tokyo crowds?
No. It compares published and historical planning signals. It does not measure live station, attraction, or neighborhood congestion.
Can I compare Tokyo-only dates?
Yes. The Tokyo guide link opens the optimizer with Tokyo preselected; you can then enter two trips of three to thirty days.
