JMSDF P-3C MPA and Asagiri-class Destroyer Detected a Submerged Submarine in Sea of Japan

The Japanese Ministry of Defense issued the following statement:

On the morning of February 15th, the Maritime Self-Defense Force (MSDF)'s P-3C, patrol helicopter, and the destroyer Asagiri confirmed a submerged submarine in waters southeast of Tsushima (Nagasaki Prefecture) within the contiguous water zone, navigating in the southwest from the Sea of Japan toward the East China Sea.

Thereafter, MSDF confirmed that the submarine navigated in the southwest through the Tsushima Strait Eastern Channel.

The contiguous zone is a band of water extending from the outer edge of the territorial sea to up to 24 nautical miles (44.4 km; 27.6 mi) from the baseline, within which a state can exert limited control for the purpose of preventing or punishing "infringement of its customs, fiscal, immigration or sanitary laws and regulations within its territory or territorial sea". This will typically be 12 nautical miles (22 km; 14 mi) wide, but could be more (if a state has chosen to claim a territorial sea of less than 12 nautical miles), or less, if it would otherwise overlap another state's contiguous zone.
