If someone in Japan falls asleep with his or her head on you shoulder, it is common practice to just tolerate it.
People have very long commutes and work dreadfully long hours, so many will often fall asleep on the train.
It is an honor in Japan to be invited to someone's home, and if this happens, you must always bring a gift.
The gift should also be wrapped in the most elaborate way possible, and lots of fancy ribbons are suggested.
Many also consider it rude to eat in public or on the trains.
There are just a few exceptions to this rule, including the fact that it is OK to eat an ice-cream cone on the street.
The setup is a cheap alternative to a hotel, as a bed costs only $65 a night, but it should be avoided for anyone who suffers from even slight claustrophobia.
