I’ve been watching a number of WW2 films and I realized that Japan is such a tiny country, so it baffles me how they had so many troops. Did they require all the males healthy or not to join the war?

In 1940:
Japan: 70 million people
USA: 130 million
India: 320 million
world: 2.3 billion
today:
Japan: 120 million
USA: 330 million
India: 1.4 billion
world: 8.1 billion
Japan has always been densely populated, with deceptively more people than its land area suggests.
But back then, Japan had about half of the US population, and a fifth of India’s. It had, by 1940 standards, tons of people … and with a pretty young and healthy population.
Today Japan has about a third of the US population, and less than a tenth of India’s. Japan’s population is a lot more elderly today too.
