Just six asylum seekers were granted refugee status by the government last year, the lowest number in 15 years, the Justice Ministry said Thursday, as experts and refugee supporters expressed outrage over what they say is yet another testament to Japan's insularity.

Out of the six, three were turned down in the initial interview process and had to re-apply. By nationality, three of the six were identified as coming from Myanmar.

Immigration authorities dealt with 3,777 cases in 2013, including re-applications. The refugee recognition rate stood at a meager 0.16 percent. This compares with the 0.6 percent in 2012.
