Despite risks of increasing talent shortages as it's population ages, Japan remains reluctant to open it's labour market to immigrants. As a result, the country becomes less attractive for investors, both japanese and foreign, who prefer places like Hong kong and Singapore.

Despite being comfronted to risks of talent shortages because of it's aging population, Japan hasn't yet accomplished it's revolution towards encouraging immigration. The country actually chooses to do the opposite, encouraging both foreign workers and graduates from it's universities, to return home and tightening the conditions to access it's labour market.
For the first time in 50 years, the number of registered foreigners fell in 2009. The overall Foreign population hence represents 1,71% of Japan's population of 127,5 Millions.
