I watched a TV program interviewing foreign travelers these days. Accounting to the interviewees, one of the most surprising things they saw in Japan was people sleeping on trains, especially women. They, travelers from some different countries, said that they don’t sleep on a train definitely because their bags are likely stolen in their countries.
But sleeping on a train is common for us, although sometimes I am surprised by some people who have an unbelievable skill – sleeping in a standing position.
This thing suggests that Japan is very safe country, but please pay attention during a travel.
