Do I need a Japan Rail Pass for this trip?

No. A JR Pass is only cost-effective if you are traveling between multiple cities like Kyoto and Osaka. For 3 days in Tokyo, pay-as-you-go with an IC card is cheaper.

Is it rude to tip in Tokyo?

Yes. Tipping is not part of the culture and can be seen as confusing or insulting. Just pay the bill exactly as shown.

How to plan a 3-day Tokyo itinerary

To see Tokyo in 3 days, split your time by geographical districts to minimize travel time. Spend one day in the west for culture and neon, one day in the east for history and old-town vibes, and one day for shopping and modern architecture.

Master the transit map. Download the 'Japan Transit by Jorudan' app or use Google Maps. Buy a Welcome Suica or Pasmo card at the airport arrival hall to tap-and-go on all subways and buses.
Group your districts. Stay in one central area like Shinjuku or Shibuya. Don't try to cross the city more than once a day; Tokyo is massive and transit time adds up quickly.
Book high-demand tickets early. If you want to visit Ghibli Museum or teamLab Borderless, buy tickets online exactly 30 days in advance, as they sell out within minutes.
