The first day I would build
Give the city one clear route before adding extras.
- Start with Aso Rock and Millennium Park while energy is high.
- Use Jabi Lake as the natural reset instead of crossing town too early.
the easier plan is Central Area first, Wuse or Maitama for food, Jabi Lake later. That keeps the day readable instead of turning every good name into a separate detour.
I would rather leave one place for tomorrow than drag a tired route through Wuse Market just because it looked close on a map.
