Do I need to tip in Tokyo?

No. Tipping is not practiced and can be considered confusing or rude.

Can I use my credit card everywhere?

While major stores accept cards, small ramen shops and older shrines are cash-only. Keep 10,000 yen in cash on you at all times.

5 Days in Tokyo: A Practical Itinerary

Plan your Tokyo trip by grouping neighborhoods by proximity to minimize transit time. Stick to one major ward per day to avoid spending three hours a day on the subway.

Get your IC card immediately. Upon arrival at Haneda or Narita, visit a ticket machine and buy a Suica or Pasmo card (or add a digital version to your Apple/Google Wallet). You need this to tap in and out of all trains and buses.
Use Google Maps for navigation. Google Maps is highly accurate for Tokyo train platforms, departure times, and exit numbers. Look for the specific 'exit letter and number' (e.g., A5) suggested by the app, as Tokyo stations have dozens of exits.
Book high-demand attractions early. If you want to visit Ghibli Museum or Shibuya Sky, book exactly 30 days out. These sell out within minutes of being released online.
Eat your main meal at lunch. Many high-end restaurants in Tokyo offer 'lunch sets' that cost 30-50% less than the exact same meal served at dinner. Plan your splurge meals during the midday window.
