Manila, Philippines – In a landmark shift signaling deepening regional security ties, Japan will send combat troops to the Philippines for the annual Balikatan exercises, marking the first time since World War II that Japanese forces will participate in large-scale drills on Philippine soil. The move underscores a growing alignment among the Philippines, the United States, Australia and Japan in response to evolving security challenges in the Indo-Pacific region.
The participation of the Japan Self-Defense Forces (SDF) represents a significant departure from the post-war constraints placed on Japan’s military posture. Whereas Japan has engaged in joint exercises with the Philippines before, these have typically involved non-combat roles, such as humanitarian assistance and disaster relief. This year’s Balikatan exercises, expected to be the largest iteration to date, will see Japanese troops engaging in live-fire drills and other combat-related training alongside their counterparts from the Philippines, the U.S., and Australia. The exercises are focused on enhancing interoperability and strengthening collective defense capabilities.
Philippine Armed Forces chief Gen. Romeo Brawner Jr. Indicated earlier this month that approximately 1,000 SDF troops could be deployed for the exercises, which are scheduled to begin in April. However, the Japanese Defense Ministry has not officially confirmed the exact number of personnel it will send, citing operational security concerns. Reuters reported on March 15, 2024, that the deployment is a key element of a broader security cooperation agreement between Tokyo and Manila.
Strengthening Alliances in a Changing Security Landscape
The decision to include Japanese combat troops in Balikatan comes amid rising tensions in the South China Sea and growing concerns over China’s military assertiveness in the region. The Philippines, a key U.S. Treaty ally, has been increasingly vocal in its opposition to China’s territorial claims and its actions to obstruct Philippine access to its exclusive economic zone. Japan shares similar concerns and has been bolstering its defense capabilities and security partnerships in response.
“Here’s a natural progression of our deepening security cooperation with Japan,” explained a Philippine defense official, speaking on background. “We recognize the shared challenges we face and the need to work together to maintain peace and stability in the region. The Balikatan exercises provide a valuable opportunity to enhance our interoperability and demonstrate our collective resolve.”
The Balikatan exercises, which translates to “shoulder-to-shoulder” in Filipino and English, have been held annually since 1951. They initially focused on training for counter-insurgency operations but have evolved to encompass a wider range of military activities, including maritime security, humanitarian assistance, and disaster relief. The official Balikatan website provides details on the exercise’s history and objectives.
What to Expect During the Drills
While specific details of the exercises are classified, officials have indicated that they will include live-fire training, amphibious landings, and maritime interdiction exercises. The drills will take place at various locations throughout the Philippines, including Luzon and Palawan, areas strategically important for monitoring activity in the South China Sea. The focus will be on enhancing the ability of the four nations to respond to a range of security threats, including terrorism, piracy, and natural disasters.
The inclusion of Japan’s combat troops will likely involve training scenarios focused on combined arms operations and coordination between different military branches. Experts suggest that the exercises will also provide an opportunity to test new technologies and tactics, as well as to refine command and control procedures. The exercises are not intended to be a show of force directed at any particular country, officials have emphasized, but rather a demonstration of the commitment of the four nations to maintaining a free and open Indo-Pacific region.
A Historical Context: Japan’s Evolving Security Role
Japan’s post-World War II constitution, drafted under U.S. Occupation, placed significant restrictions on its military capabilities, limiting them to self-defense. However, in recent years, Japan has been gradually expanding its security role, driven by concerns over North Korea’s nuclear weapons program and China’s growing military power.
In 2015, Japan revised its security laws to allow the SDF to engage in collective self-defense, meaning it can arrive to the aid of allies even if it is not directly attacked. This change paved the way for greater security cooperation with countries like the United States, Australia, and the Philippines. The current deployment to the Philippines represents a further step in this direction, signaling Japan’s willingness to take on a more proactive role in regional security.
The historical sensitivity surrounding Japan’s military presence in the Philippines, given its occupation during World War II, is acknowledged by both governments. Officials stress that this deployment is fundamentally different, representing a partnership based on mutual respect and shared security interests. The focus is on cooperation, not confrontation, and on building a more secure and stable future for the region.
The next official update regarding the Balikatan exercises, including the confirmed number of Japanese troops participating, is expected in early April, according to the Philippine Department of National Defense. Further details on specific training scenarios will be released closer to the start of the drills.
