MEMPAWAH, INDONESIA — A Japanese military transport ship docked in Mempawah district on the island of Borneo on Thursday as part of a disaster relief mission. Japan deployed 300 crew members, landing ship JS Kunisaki, and three CH-47 helicopters to Kalimantan on the island of Borneo. The three CH-47 Chinook helicopters from Japan will start conducting firefighting operations on Borneo as soon as preparations are complete.

Colonel Syunji Nakahara addressed the mission's objectives during a press conference. "Through these operations, we will dedicate ourselves to supporting the affected people of Indonesia and preventing further damage," he said. He added that the forces would coordinate closely with local counterparts. "To this end, we will learn from the Indonesian military’s operational experience and work in coordination and cooperation with them, striving to ensure that the Indonesian people can lead stable lives as soon as possible," Nakahara said.

An intensifying El Niño pattern and a prolonged dry season worsened the impact of forest and land fires in Indonesia. Indonesia’s Forestry Ministry recorded more than 202,000 hectares of burned land between January and July. The toxic haze affected more than 1.4 million students across Indonesia. Air pollution affected several areas on the island of Sumatra, forcing schools to suspend learning activities.

The environmental impact extended beyond Indonesia's borders. Smoke from the wildfires drifted more than 800 kilometers to the Philippines. Air pollution breached Malaysia’s emergency-level threshold, forcing authorities to declare an emergency last week in a town in Sarawak state on Borneo. Indonesian authorities have escalated firefighting efforts in several provinces involving aircraft provided by Japan, the United States, Russia, Australia, Canada, and Ukraine.

Why It Matters

This mission represents an expansion of the Japan Self-Defense Forces' international role, marking their first known overseas firefighting operation. The scale of the deployment, involving hundreds of personnel and specialized aviation assets, reflects the severity of the regional crisis caused by the wildfires. The toxic haze has disrupted education for over 1.4 million students in Indonesia and triggered emergency declarations in neighboring Malaysia, indicating the cross-border nature of the environmental disaster.

The operation occurs within a broader context of strengthening military cooperation ties between Japan and Indonesia, which are currently discussing the Japanese sale of used destroyers. By coordinating with the Indonesian military and contributing to multinational firefighting efforts that include assets from the United States, Russia, Australia, Canada, and Ukraine, Japan is engaging in direct operational support for disaster relief in Southeast Asia. The success of these efforts depends on completing preparations for the CH-47 helicopters and integrating their capabilities with ongoing regional responses.
