The problems with depopulation is that there is no permanent vacuum. If the countryside is empty it will refill, whether you mean for it or not. Whether this is good or bad is not the point here, but that it will happen. Japan is an island nation that doesnt encourage migrants, so they may put it off. The best thing they can do is make a controlled immigration scheme.

- dsq 3y agoLets 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. See the Sea Peoples at the collapse of the Bronze Age.
- The_Colonel 3y agoPopulation of Japan is projected to be 50 million (25 million of those in productive age) in 2120, that seems like enough to defend the relatively small island nation.

See the Sea Peoples at the collapse of the Bronze Age. They'd have no chance against an organized professional military, esp. in foreign environment, no chance to blend into the local population etc.
