Fushin-sen are used by a special unit of the North Korean regime, and the operatives on board are carefully selected. These operatives may be trained in combat tactics, such as
sniping and
Kyeok Sul Do. They may also have advanced foreign language skills, used to impersonate citizens and establish permanent residency in their destination. Operatives smuggled into Japan by seacraft are usually concealed and blend in as members of society, while they
gather intelligence or carry out orders. Such operatives may coerce others to carry out criminal activities for them. In Japan, several such operatives are wanted by

are actively working to educate civilians about the fushin-sen issue and the dangers they pose to public safety. In coastal areas, prefectural police headquarters and police stations have been conducting active seminars for companies and fishermen since the 1950s. It has not always been possible to prevent abduction and smuggling. The Japan Coast Guard recommends that citizens call 118 (the telephone number for emergency calls for incidents and accidents at sea in Japan) if a person witnesses a suspicious ship that appears to be of North Korean origin.

Kim Dae-jung (, ; 6 January 192418 August 2009) was a South Korean politician, activist and statesman who served as the eighth president of South Korea from 1998 to 2003.

, a South Korean politician, was living in exile in Japan due to his opposition to the power regime in South Korea at that time. On August 8, 1973, as he left a meeting in Tokyo, he was kidnapped by agents working for the
Korean Central Intelligence Agency. He was taken to Osaka and put aboard a boat which sailed towards South Korea. The vessel was tracked by an airplane of the Japanese Maritime Defense Force which fired an illuminating shell as the kidnappers brought Kim (with weights attached to him) on deck, apparently intending to drown him. The vessel continued to South Korea and Kim was put under house arrest. In 1998, Kim became the president of South Korea.
Suspicious ship off the Noto Peninsula
On March 23, 1999, a ship believed to be a North Korean craft ship appeared off the Noto Peninsula in the Sea of Japan. It was tracked by the Japan Coast Guard and the Maritime Self-Defense Force. For the first time, the Maritime Self-Defense Force was issued a maritime security action, a ''de facto'' battle order. The craft ship was missed, but this incident triggered the realization of hull shooting and the maintenance of patrol boats due to the revision of the Japan Coast Guard Law, as well as the formation of the Maritime Self-Defense Force's Special Boarding Unit and on-site inspection team with escort vessels.
Kyushu Southwest Sea Area Fushin-sen Incident (Battle of Amami-Ōshima)

On December 22, 2001, an unidentified vessel was detected in the East China Sea off the southwest coast of Kyushu. Four Coast Guard ships approached the vessel and ordered it to halt. When it did not, the Coast Guard fired warning shots, and the unidentified vessel returned fire. A six-hour gun battle ensued, ending when the unidentified vessel apparently

When the South Korean Navy pursued the ship, an incident occurred in which it was sunk on the open sea off Tsushima, Nagasaki Prefecture. A later pull-up investigation revealed that the suspicious ship was a North Korean semi-submersible. Until March 1999, the Japan Coast Guard strengthened vigilance off the coast of Tsushima and provided crime prevention guidance to residents of Tsushima and the Goto Islands.
