It's always interesting to look at historical population charts. They often show that current population levels are a blip. In Japan's case, population is currently about 124 million. It was about 30 million and almost stable until the Meiji era (~1865+), and was 70-75 million in 1945. What's happened is a massive boom during approximately the 20th century, from 40 to 125 million.
