Law Enforcement & Security[edit]

Japan ratified the United Nations Convention on the Law of the Sea (UNCLOS) on 10 December 1982 and has contributed to three UNCLOS organizations such as the International Tribunal for the Law of the Sea (ITLOS), the Commission on the Limits of the Continental Shelf (CLCS) and the International Seabed Authority (ISA).[5]

The Japan Maritime Self Defense Force (JMSDF) is responsible for protecting the EEZ of Japan; as an island nation, dependent on maritime trade for the majority of its resources, including food and raw materials, maritime operations are a very important aspect of Japanese defense policy.


Japan has disputes over its EEZ boundaries with all its Asian neighbors (Russia, Republic of Korea, China and Taiwan); the above, and relevant maps at the Sea Around Us Project[6][7] both indicate Japan's claimed boundaries.

Japan also refers to various categories of "shipping area" – Smooth Water Area, Coasting Area, Major or Greater Coasting Area, Ocean Going Area – but it is unclear whether these are intended to have any territorial or economic implications.
