Does Shintoism focus on any gods?

This is a difficult question to answer since it is very
difficult to define exactly what a "god" is.  It is certainly possible to argue that
Shintoism has gods and that some of them are the focus of more veneration than others. 
It is also possible, however, the call the kami that are the object
of Shinto worship "spirits" rather than "gods."

Shinto
belief holds generally that there are huge numbers of kami that can
have an impact on the lives of human beings.  In this sense, the
kami can be seen as gods since they affect our lives and since
devotees of Shintoism believe that their favor can be obtained through proper ritual
practice.

Of these many kami, some are
more important than others.  Perhaps the most important is Amaterasu, the "sun
goddess."  She is seen as the progenitor of the Japanese royal family and has been one
of the most important kami in Shintoism.
