Why is the purpose of the Japanese tourist in Chapter 6?what the message the author want when he mention japanese tourist in this chapter

Gilead is visited by a group of Japanese tourists who are
looking at the people there much as we would look at those in the Middle East,
especially the women in burqas.  One tourist asks the Gilead women if they are happy.
 They cannot answer truthfully.

This scene serves to show
the complete change in culture in the United States and Canada.  The people of Gilead
live repressed lives in fear of government retaliation.  By using the Japanese tourist,
Atwood reminds us that the entire world has not become this dystopia, but that the
others are powerless to help.  They remain ignorant of the atrocities that are occurring
in this new land.

We understand if change is to occur, it
will have to come from within.  The outside world is not aware of the plights of the
people of Gilead.
