The Japanese government says it will within the year present to a court video footage of a Sri Lankan woman before she died while in detention in central Japan.

Relatives of Wishma Sandamali are suing the state for damages. She died at an immigration detention facility in Nagoya City in March of last year. She had complained of feeling ill before her death.

Her family filed a lawsuit with the Nagoya District Court, demanding the government pay compensation of over 150 million yen, or more than 1 million dollars.

The family members argue that their loved one was illegally detained without a provisional release and did not receive the necessary medical care when her health deteriorated.

The government says her detention was based on the immigration control law and was legitimate. It says there was nothing illegal about the authorities' responses, which included medical checkups.

After the court asked the government to present an approximately 5-hour section of footage taken of the woman during her detention, the government indicated its readiness to do so.

On Monday, the government said it will submit the video to the court within the year.

A sister of Wishma, Wayomi, reiterated her call for all 295 hours of the footage to be presented, saying that is what is necessary to uncover the truth.
