Lets say Japan's population keeps falling. It should be remembered that the demographic pyramid will be inverted, with mostly old people. In that case there would not be enough military aged persons to run an effective military. AI and robots could help, but any invaders would have AI and robots too.
Potentual invaders would not necessarily be another nation state. It could be roving groups of displacees who took up piracy and invasion.
