Politicians and the media invoke the certainty of social instability should the number of foreigners rise. The justice ministry attributes high rates of serious crime to foreigners—though, when pressed, admits these are committed by illegal immigrants rather than legal ones. Newspaper editorials often give warning of the difficulties of assimilation.

For the first time, however, an 80-strong group of economically liberal politicians in the ruling Liberal Democratic Party (LDP), led by Hidenao Nakagawa, a former LDP secretary-general, is promoting a bold immigration policy. It calls for the number of foreigners to rise to 10m over the next half century, and for many of these immigrants to become naturalised Japanese. It wants the number of foreign students in Japan, currently 132,000, to rise to 1m. And it calls for whole families to be admitted, not just foreign workers as often at present.

The plan’s author, Hidenori Sakanaka, a former Tokyo immigration chief and now head of the Japan Immigration Policy Institute, envisages a multicultural Japan in which, he says, reverence for the imperial family is an option rather than a defining trait of Japaneseness. It’s a fine proposal, but not very likely to fly in the current political climate, especially at a time when the opposition Democratic Party of Japan is fretting about the impact of immigration on pay for Japanese workers.

Still, a declining workforce is changing once-fixed views. Small- and medium-sized companies were the first, during the late 1980s, to call for more immigrant workers as a way to remain competitive. The country recruited Brazilians and Peruvians of Japanese descent to work in the industrial clusters around Tokyo and Nagoya in Aichi prefecture that serve the country’s giant carmakers and electronics firms.
