The Maritime Self-Defense Force's Pacific Surveillance Network Demonstrated by the IPD26 Inspection Team in Kiribati

In the announcement from the Maritime Staff Office dated August 3, what first caught my attention was not the name of the ship but the place name "Tarawa." The IPD26 unit, part of the Indo-Pacific deployment for the fiscal year 2023, conducted inspection training with personnel from the Maritime Police Department of Kiribati from July 27 to 30 in Tarawa, Kiribati. The participants were the IPD26 inspection team from the Japan Maritime Self-Defense Force, and the training focus was on inspections.

The Geographical Significance of a Small Training Exercise

At first glance, this is neither a large-scale exercise of escort ships nor a missile launch. However, from the perspective of the Maritime Self-Defense Force, inspections are a technique that supports the foundation of maritime order. Boarding, identity verification, document checks, ensuring movement lines within the ship, and sharing terminology with personnel from the host country. These may not be flashy, but neglecting training can quickly reveal flaws.

Kiribati has a vast maritime area in the central Pacific. According to basic data from the Ministry of Foreign Affairs, diplomatic relations between Japan and Kiribati were established in March 1980, and Japan's economic cooperation has continued for a long time. This training can be seen as placing the intersection of defense and maritime law enforcement along that continuum.

Measures Against IUU and the Tactical Skills of the Maritime Self-Defense Force

The announcement from the Maritime Staff Office cites the improvement of the tactical skills of the Maritime Self-Defense Force and the strengthening of cooperation with the Kiribati Police as objectives. What is important here is that the counterpart is not the navy but the Maritime Police Department. In many Pacific island nations, the primary threats are not fleet confrontations with regular military forces but rather everyday maritime risks such as illegal, unreported, and unregulated fishing, drug trafficking, and maritime traffic disruptions during disasters.

Documents from the FFA also indicate that regional cooperation and information sharing are essential for managing EEZs and monitoring fisheries in Pacific countries. Japan's entry into this area with specific capabilities for inspections is not insignificant. If one only observes the movements of the Chinese Navy, such training may appear to be a supporting role. However, SLOCs (Sea Lines of Communication) can only be utilized in emergencies if there is a network of port operations, coastal security, and fisheries monitoring in peacetime.

The Role of Supplementing the Outer Edge of the Japan-U.S. Alliance

The deterrent power of the Japan-U.S. alliance is not solely based on aircraft carriers, submarines, and missile defense. Outside the first island chain, particularly in the central Pacific, the overlap of U.S. military mobility and Japan's continuous involvement creates the depth of surveillance. Deployments like IPD26 are more about building port calls, joint training, and mutual understanding than showcasing combat power.

In my view, the value of this Tarawa training lies not in "incorporating Kiribati" but rather in what Japan can learn from the law enforcement practices of island nations. Countries that monitor vast oceans with small numbers of personnel have a sense of prioritization with limited equipment. If the Maritime Self-Defense Force discusses the defense of the southwestern islands and remote islands, this sense cannot be ignored.

Remaining Challenges

However, if the training ends after just one session, the effectiveness will be minimal. What is needed is to continuously align inspection procedures, communications, evidence preservation, and command relationships after boarding. The true challenge lies not in where to deploy large ships but in the political endurance to ensure that small joint training exercises are not interrupted every year.
