Group Tokyo instead of maxing it
Tokyo works better when each day has one clear zone and one optional side stop.
Arrival day
Keep the first day close to the hotel and low pressure.
West Tokyo
Use Shibuya, Harajuku, Omotesando or Shinjuku for energy, shopping and evenings, but do not do everything.
East Tokyo
Use Asakusa, Ueno, Yanaka, Kappabashi, Ginza or Tokyo Station for culture, markets and a calmer rhythm.
Practical rule
Choose one main zone, one side stop and food nearby.
