The government released video footage Friday showing last week's collision between a Fisheries Agency patrol ship and a North Korean fishing vessel in an effort to demonstrate that Japan took appropriate action.
The 13-minute video shows that the North Korean vessel sank after colliding with the Fisheries Agency patrol ship, the Okuni, on Oct. 7 off Ishikawa Prefecture in the Sea of Japan, conflicting with a claim by Pyongyang that Japan deliberately sank the fishing vessel.
The Okuni directed a water cannon at the North Korean vessel after it failed to comply with a warning to leave the waters in Japan's exclusive economic zone, the footage shows.
