How identity is constructed and used to convey ideas about gender, class, race and age in Patriotism by Yukio Mishima?

For Mishima, in both life and his work, identity is
strongly connected to national identity.  The mere title,
Patriotism, helps to bring this out.  Mishima constructs identity
as something as something that is strongly linked to the notion of one's national
affiliation.  The fact that the soldier has to take his own life in deference to
national honor and not undermine the natural order of national rule helps to make his
decision.  His wife, being the good wife of a national soldier, decides to take her own
life in the same notion of honor.  In both of their settings, honor is defined by
national affiliation.  The soldier could certainly define himself in elements that
distance himself from national identity, yet this would be seen as dishonorable.  His
decision to take his own life and knowing that his wife will follow is made in the light
of national honor or prestige.  Even when they are making love, both of them understand
that one of them is a soldier and the other one is a soldier's wife.  National honor has
defined them both to a great extent.  In this light, nationalism helps to define one's
identity.
