Japan's Fisheries Agency has uploaded to its website a video clip of the recent collision between an agency patrol ship and a North Korean fishing boat.
The 13-minute video shows the patrol ship spraying water at the fishing boat, warning it to leave Japan's exclusive economic zone in the Sea of Japan.
The video shows the North Korean boat making an abrupt left turn. The bow of the patrol ship then collides with the fishing boat's port side.
The footage also shows the patrol ship crew rescuing the North Koreans using lifeboats and rafts as their boat sank. It then shows the rescued crew members boarding another North Korean ship.
The agency uploaded the footage to its website after releasing it at a news conference on Friday.
The collision occurred on October 7 inside Japan's exclusive economic zone off the Noto Peninsula in Ishikawa Prefecture, central Japan.
North Korea has demanded financial compensation and preventive measures over the incident. It accuses Japan of putting the crew's life in danger.
The Japanese government has rejected the claim. By releasing the video, the Fisheries Agency hopes to gain understanding of its efforts to control illegal fishing.
