American's and Japanese have difference of feature. We can see in every aspect of our
life. American some elderly ladies dressed freely but Japanese old lady dressed similar.
In New York here are many examples about age. A person when came here have scarcely
of my age. The people think about age.
The woman when remains single beyond that age people said usually old maid. Because the people
don't married. Some different idea, different customs. American strongly describe their opinions, but
Japanese speak with consideration of others feelings. The american people is individualism, each
one think about themselves, don't care the other people. America is a big country, there are people
from many countries, however Japan is a small country. In America the people is autonomous but in
Japan no because the circumstances are different.
