Travel Essentials

Japan Quick Tips

Getting Around

Get a Suica/Pasmo Card

Rechargeable IC cards work on all trains, buses, and even convenience stores. Buy one at any JR station.

Avoid Taxis

Taxis are extremely expensive. A 10 minute ride can cost $20+. Use trains instead.

JR Pass for Long Distances

If visiting multiple cities, the Japan Rail Pass saves hundreds on Shinkansen (bullet train) tickets.

Money & Payments

7-Eleven ATMs Are Best

Most Japanese ATMs don't accept foreign cards. 7-Eleven and Japan Post ATMs always work.

Cash is King

Japan is still largely cash-based. Many restaurants and small shops don't accept cards.

No Tipping Culture

Tipping is not expected and can even be considered rude. The price you see is what you pay.

Staying Connected

Limited Free WiFi

Unlike other countries, free WiFi is rare in Japan. An eSIM is essential for navigation.

Google Maps Works Great

Google Maps has excellent train schedules and walking directions in Japan.

Download Offline Translation

Google Translate's camera feature can translate Japanese menus and signs instantly.
