More than the total number that foreigners come to Japan...The report of 法务省(厚生省/劳动省?)
The name of Japanese gov always remind me of the scaring thing----We have to memorize the ancient China's government departments names..WTF
(like中书省 门下省 尚书省 大理寺 鸿胪寺 宗人府 内务府 詹事府)
There is also a considerable number of Japanese-Peruvians; nearly 200,000 of them. We have nearly 1.5 million Japanese in America, nearly 200,000 in the Philippines, nearly 200,000 in China, nearly 110,000 in Canada etc etc.
Basically Japan can easily solve our population crisis if we can encourage our overseas population to come back to Japan.
