When on the train in Japan (where you will probably spend much time), you can typically choose any of the three following activities:
- play with your smartphone
- read a book
After reading my guide to the handiest apps for travelling Japan, I am sure you will opt
for the ‘smartphone’ choice!
However, be sure not to talk on the phone in the train. It is considered
very rude in Japan. Just to make sure, a Japanese intercom lady will remind you
of this constantly when you ride the train ;-)
