There were two times since 1915 till 2012 Japan's population reduced. The first time was during the WWII, and the second time was from 2010 to 2012. It's only in two years Japan lost somewhat 500,000 people. It's not that many considering the worst scenario with the nuclear problem happening in Japan. But the death count is something only half of the number of the people died during WWII... Well, the graph says that it was in 5 years about 1,000,000 people died in the war. The latest depopulation is of only 2 year scale. You can guess what would it be in 5 years. I bet the death count is going to be more after 4 years as that is the period when the radioactive health problem would be more visible to the public. Everyone in Japan would be hospitalized from the cancer, I bet.
