Russian Ships Sail Through Tsugaru Strait

According to the Japanese Ministry of Defense, three Russian Navy ships sailed through the Tsugaru Strait on June 18th. The announcement reads below:

The Tsugaru Strait is a strait between Honshu and Hokkaido in northern Japan connecting the Sea of Japan with the Pacific Ocean. Japan’s territorial waters extend to three nautical miles into the strait instead of the usual twelve allowed by the UN Convention on the Laws of the Sea.

Despite this, the part of the Tsugaru Strait considered to be in international waters is still within Japan’s exclusive economic zone, making foreign warship passages extremely sensitive. The Seikan Tunnel remains entirely under Japanese jurisdiction even though part of it is technically outside Japan’s territorial waters.
