1. Buy the JR pass before your arrival.
2. Bring cash – and lots of it.
3. Pack slip on shoes.
4.Tattoos are considered taboo.
5. Keep your voice to a minimum.
6. Convenience stores in Japan are WAY different than the ones in America.
7. Rent a pocket WiFi device.
8. English isn't widely spoken in Japan – even in tourist areas.
9. Pack as lightly as possible.
Don’t pack a large suitcase to share between two people – I repeat: Do NOT bring a large suitcase to Japan! Train stations in Japan are often packed with people and escalators and elevators can be limited. This means you’ll be lugging a large suitcase up and down multiple stairs and through hoards of people to get to your platform. In addition, the dedicated spaces for luggage are often small and made to fit only carry-on luggages. To make life easier, pack light when visiting Japan!
10. The metro is not opened 24 hours.
The train system in Japan can stop service anywhere between 11:30pm and 1:00am. If you miss the train, you’ll be left stranded until service resumes at 5am. Of course, you can always take a cab or Uber back to your hotel but it will be expensive. To avoid such a hot mess of missing the train, be sure to plan your night accordingly and catch the train by 11pm JUUUSTTT in case.
