    $root->Area->Region->[0]->cd;
    $root->Area->Region->[0]->name;
    $root->Area->Region->[0]->Prefecture;
    $root->Area->Region->[0]->Prefecture->[0]->cd;
    $root->Area->Region->[0]->Prefecture->[0]->name;
    $root->Area->Region->[0]->Prefecture->[0]->LargeArea;
    $root->Area->Region->[0]->Prefecture->[0]->LargeArea->[0]->cd;
    $root->Area->Region->[0]->Prefecture->[0]->LargeArea->[0]->name;
    $root->Area->Region->[0]->Prefecture->[0]->LargeArea->[0]->SmallArea;
    $root->Area->Region->[0]->Prefecture->[0]->LargeArea->[0]->SmallArea->[0]->cd;
    $root->Area->Region->[0]->Prefecture->[0]->LargeArea->[0]->SmallArea->[0]->name;

=head2 xml

This returns the raw response context itself.
