Japanese Fingerprinting of Foreigners

Immigration has been a hot policy issue across the globe, and many countries are figuring out how to balance open borders and homeland security. According to JapanToday.com, beginning Nov. 20 Japan will implement a mandatory fingerprinting and photograph of foreign visitors 16 and older. The article stated that this was apart of the revised Immigration Control and Refugee Recognition law, which was enacted May of last year to prevent entry of terrorist as deemed by the justice minister. This information would be stored in a computer system, which can then be accessed by Immigration and investigative authorities. Personally, I think this can be as effective but I still feel it is impossible to "keep out of harms way" completely, and trouble almost always finds a loophole. Although, the Japanese government excludes the fingerprinting of ethnic Koreans, diplomats and people under the age of 16. This policy has a hint of xenophobia or rather a tendency to create even more xenophobic tendencies in Japanese citizens. My issue with policies such as this one, is there discriminatory nature and the frequent tendency for immigration policies to be synonymous with controlling terrorism. I really have issues with terrorism and immigration being one and the same, and while I understand the correlation I am not finding how they are the same. Maybe I am missing a big piece of the political puzzle, but I feel as if politicians and policymakers need to reevaluate their approach to controlling terrorism.
