If Japan wants to survive as a nation the youngsters had better “get busy”.
If Japan has been suffering from excessive population for many many decades, then maybe a reduction in population would give the Japanese more elbow room to more freely move around. Seriously, how many years does a Japanese person get packed in like a sardine in little bitty container before he starts thinking about needing a larger living space?! Like reduce the population by 25% and have more room in the housing inventory!
