The Yomiuri Shimbun newspaper reported citing own sources that the plan implied evacuation of people from South Korea to the Japanese island of Tsushima and later to Kyushu.
The plan could be implemented if the airport of Seoul is blocked or unable to operate after an emergency situation, the newspaper added.

According to the media outlet, the Japanese government has also taken into consideration the fact that South Korea prohibits the ships of the Japan Maritime Self-Defense Force (MSDF) to enter its port, so the Japanese sailors could use the US ships for transportation of people to the MSDF ships before sending them to Tsushima.
The tensions around North Korea's nuclear program have remained high over the past year due to the country's repeated nuclear and ballistic missile tests, all of which were in violation of UN Security Council (UNSC) resolutions. As a response measure, the UNSC has introduced multiple sanctions against Pyongyang with the aim of hampering the development of its nuclear program.
