In response to this Convention, Japan and the United States shared the search and rescue activities on the Pacific Ocean by concluding "Agreement on search and rescue at sea between the Japanese government and the United States government" (Japan-US SAR agreement).

The scope of responsibility for Japan was north of 17 degrees north and 165 degrees east longitude, which meant sending rescue units from the coast of Japan to a distance of 1,200 nautical miles (2,200 km).

At the end of 1980, certain large scale marine accidents occurred, and in March 1981 accidents of large tankers and cargo ships occurred in the Malacca Straits, and the development of wide area patrol system became an urgent task.

[citation needed] From 2 September to 11 November 1989, the year after its completion, the Japan Coast Guard patrol boat made its first round-the-world voyage.

In the United Kingdom, joint training with the Coast Guard and the Royal National Lifeboat Institution was conducted, which was televised worldwide by the British Broadcasting Corporation (BBC).
