Our fleet was built with a defensive intention, but it comes at a cost as we forgo buildings. The cost needs to be paid, if not entirely by ourselves.
We are not aiming for domination victory so non-coastal capital is irrelevant. The path of ideology will not work for us any more, because we have adopted the doctrine of economic analysis for the entire board of games: i.e. if the cost of war is low enough, we will go for it, unless we encounter resistance enough to no longer sustain the war economically. Therefore, Japan is unfortunately under the test now.
