This week the internal affairs ministry released preliminary results of the 2010 census. According to news articles, the population rose slightly to 128 million, with immigration cited as one reason for the gain. At the same time, the far-flung regions of Japan continued to hollow out as people moved to and closer to urban areas, especially Tokyo. Other population estimates show Japan’s population seesawing up and down around 127 million, and the official projection is for the population to shrink to around 100 million by 2050.
The number of households continue to increase faster than the population with the rise of smaller and single-person households.
More detailed census data will be coming in the months ahead.
