3 Days in Tokyo: A First-Timer's Itinerary

Start at Senso-ji, Tokyo's oldest temple, and walk the Nakamise shopping street leading up to it for snacks and souvenirs. In the afternoon, Ueno Park is a short train ride away, with museums if the weather's bad and a big park if it isn't.

Shibuya Crossing in the morning before it's at its busiest, then Harajuku's Takeshita Street for youth fashion and crepes, and a walk through the forested approach to Meiji Shrine, which feels dramatically different from the streets around it.

Day 3 is where the trip planner tool on this site is useful — it'll suggest a third day based on what you told it you're actually interested in (anime, nature, shopping, or food), since Tokyo genuinely has a strong option for each.
