In a speech that was due to be delivered in Jakarta on 18 January 2013 — but postponed due to the hostage crisis in Algeria — Japanese Prime Minister Shinzo Abe stressed the vital importance of Asia's maritime domain to Japan:

That Abe chose to focus on maritime security during his first overseas trip since assuming office on 26 December 2012 was unsurprising for two reasons. First, as an island nation largely bereft of natural resources, Japan depends for its economic prosperity on the free flow of maritime trade. Japan relies on Asia's sea lines of communication (SLOCs) for the transportation of its manufactured goods to world markets and for the importation of natural resources, including more than 90 per cent of its imported energy supplies. SLOC security has been, and remains, a critical national security concern for Japan's leaders, strategic thinkers, and security planners. The SLOCs that thread through the maritime chokepoints of Southeast Asia (including the Malacca-Singapore Straits, Sunda Straits, and Lombok-Makassar Straits) and the South China Sea link the Indian and Pacific Oceans and are therefore of singular importance to Japan's economic well-being and national security. In 2010 Japan's two-way trade with the ten members of the Association of Southeast Asian Nations (ASEAN) amounted to US$214 billion, with South Asia (India, Pakistan, and Bangladesh) to US$17.8 billion, and with the European Union (EU) to US$147 billion — the bulk of this trade being borne along Southeast Asia's sea lanes. Regional sea lanes are routinely utilized also by the Japan Maritime Self Defense Force (JMSDF), including by warships operating in the Indian Ocean as part of international efforts to counter pirates off the coast of Somalia and in the Gulf of Aden.
