How to pick a base
First trip: Shinjuku or Shibuya. Quiet plus Tokyo Station: Marunouchi. Asakusa-only days: by Kaminarimon. Odaiba is pretty — the ride back costs time.
攻略｜宿泊
Shinjuku for night and rails, Shibuya for the walking loop, Marunouchi as a hub, Asakusa for shitamachi, Odaiba for the bay. Sleep in one, ride to another — do not change hotels every night.
