The Japanese government's decision on August 28, 2026, to deploy the Japan Self-Defence Forces (JSDF) to assist in extinguishing forest and land fires in Kalimantan marks a new chapter in Indonesia-Japan bilateral relations regarding disaster management.
The deployment of three CH-47 heavy-lift helicopters, transported via the amphibious ship JS Kunisaki alongside approximately 600 personnel represent not merely a humanitarian operation but a reflection of the maturing defence diplomacy between the two nations.
The substance of this cooperation ranges from the implementation of Humanitarian Assistance and Disaster Relief (HADR) to the application of defence diplomacy between the two nations. The deployment of Japanese aid represents a concrete follow-up to the defence cooperation agreement signed by both countries in May 2026, specifically strengthening collaboration on HADR operations.
Indonesian Defence Minister Sjafrie Sjamsoeddin has emphasized that this foreign assistance embodies defence diplomacy, demonstrating that defence cooperation extends beyond enhancing military capabilities to include providing aid when a partner nation is struck by disaster.
The historical context of this cooperation is also noteworthy. Indonesia and Japan share similar geographical characteristics as archipelagic nations prone to various disasters, ranging from earthquakes and tsunamis to forest and land fires.
Japan’s extensive experience in fostering a disaster-resilient culture, through early childhood education and the adoption of adaptive technologies makes it an ideal strategic partner for Indonesia in disaster risk reduction and the management of forest and land fires on the island of Kalimantan.
The Strategic Dimension of the Kalimantan Operation
The scale of the Japanese government's assistance was substantial and well-planned. The decision to deploy resources followed a trilateral virtual meeting of defence ministers from Indonesia, Japan, and Australia on August 26, 2026, during which the leaders committed to strengthening defence cooperation and regional disaster management capabilities in the Indo-Pacific.
This indicates that the Humanitarian Assistance and Disaster Relief (HADR) operation in Kalimantan possessed a geopolitical dimension extending beyond mere humanitarian aid.
The urgency of the operation was driven by severe forest and land fires that persisted into early September. The National Disaster Management Agency (BNPB) recorded that the area of land burned in West Kalimantan alone reached 38,310.89 hectares between January and August 2026.
The fires were fuelled by intensifying El Niño patterns and a prolonged dry season, which complicated conventional firefighting efforts. In this context, CH-47 helicopters, featuring heavy-lift capabilities and high mobility were deployed, serving as strategic assets to reach areas that might otherwise be difficult to access.
Long-Term Disaster Management Cooperation
Cooperation between Indonesia and Japan in disaster management has never been limited to emergency operations; their joint activities also encompass long-term capacity building. The Japan International Cooperation Agency (JICA) has been actively involved in various disaster risk reduction programs in Indonesia, including disaster management training for civil servants and the development of the "Kita Tangguh" dashboard as a tool for monitoring national resilience.
Regarding forest fires, JICA has collaborated with Indonesia's Ministry of Environment and Forestry on the Community Movement Program on Forest and Land Fire Prevention (CMP). This initiative aims to strengthen the capacity of Manggala Agni, Indonesia's forest firefighting brigade by employing a Community-Based Fire Management (CBFiM) approach.
This method emphasizes the importance of local community involvement in fire prevention and suppression, aligning with community-based disaster risk reduction strategies.
Further, Japan has contributed to the development of innovative firefighting technologies for peatland fires, such as the use of eco-friendly, soap-based firefighting foam, facilitated through JICA's business partnership programs with Japanese companies. This approach is crucial given the nature of peatland fires, which are difficult to extinguish using conventional water methods due to the hydrophobic characteristics of the soil surface.
Regional Resilience and Public Diplomacy
Japan's relief operations in Kalimantan must also be understood within the context of regional resilience dynamics in Southeast Asia. Forest fires in Indonesia have long been a source of transboundary haze affecting neighbouring countries such as Malaysia, Singapore, and Thailand. Indonesia itself has welcomed international assistance, including from Malaysia and other nations under the framework of the Transboundary Haze Pollution Agreement.
The Indonesian government authorized the deployment of 35 foreign aircraft from eight countries, including Russia and the United States (US), to assist in firefighting operations in Kalimantan. In this context, Japan's participation demonstrates that disaster management has become a diplomatic arena involving various actors, including major powers and strategic partners in the region.
Japanese Defence Minister Shinjiro Koizumi emphasized that this deployment was grounded in the close, friendly relations between the two nations. This statement clearly underscores that foreign humanitarian aid also serves as an instrument of public diplomacy, strengthening positive images and strengthening mutual trust between countries.
Disaster Management as Strategic Cooperation
The disaster management cooperation between Indonesia and Japan regarding forest and land fire suppression in Kalimantan exemplifies how environmental and humanitarian issues have become integral to international relations and defence diplomacy.
The deployment of the Japan Self-Defence Forces involving significant equipment and personnel reflects the depth of the strategic partnership between the two nations, which focuses not only on traditional security but also on human and environmental security.
Looking ahead, this bilateral cooperation holds the potential to serve as a model for disaster response partnerships across the Indo-Pacific, enabling nations to support one another in addressing increasingly complex climate and disaster-related challenges.
For the Indonesian government, the partnership with Japan strengthens national disaster management capacity while simultaneously expanding multilateral diplomatic networks amidst the ever-evolving regional geopolitical landscape.
