Japan Maritime Self-Defense Force

The Japan Maritime Self-Defense Force (海上自衛隊 Kaijō Jieitai), or JMSDF, is the naval branch of the Japan Self-Defense Force, tasked with the naval defense of Japan. It was formed following the dissolution of the Imperial Japanese Navy (IJN) after World War II. The JMSDF has a large fleet and its main tasks are to maintain control of the nation's sea lanes and to patrol territorial waters. It has also stepped up its participation in UN-led peacekeeping operations (PKOs) and Maritime Interdiction Operations (MIOs).
