The family of a Sri Lankan woman who died after being detained for overstaying her student visa visited an immigration facility in Aichi Prefecture on Monday to hear from officials about the circumstances leading up to her death.

Ratnayake Liyanage Wishma Sandamali, 33, who was being held at the Nagoya Regional Immigration Services Bureau in the prefecture, died on March 6 after having complained of stomach pain and other symptoms from mid-January.

Her death, which activists blame on a failure to provide appropriate medical attention, has been cited as evidence of problems riddling Japan's immigration and asylum system, particularly with regard to the indefinite detention of foreign nationals facing deportation.
