Japan Deploys Long-Range Missiles in Response to Regional Tensions

Tokyo – Japan is accelerating its military modernization with the deployment of domestically produced, long-range missiles, marking a significant shift in its defense posture. Launchers arrived at Camp Kengun in Kumamoto Prefecture, southwestern Japan, on Monday, March 9, 2026, with full deployment expected by the end of the month .

Strengthening Counterstrike Capabilities

The upgraded Type-12 land-to-ship missiles, developed by Mitsubishi Heavy Industries, represent a substantial increase in Japan’s ability to respond to potential threats. The missiles have a range of approximately 1,000 kilometers (620 miles), extending significantly from the original Type-12’s 200-kilometer (125-mile) range . This extended range allows Japan to potentially reach targets in mainland China.

Deployment and Regional Concerns

The deployment is occurring amidst escalating regional tensions, particularly concerning China’s increasing military activity around Taiwan and North Korea’s continued development of ballistic missiles . Japan’s Defense Ministry accelerated the deployment schedule by one year, signaling the urgency with which it views these challenges.

The arrival of the missile launchers at Camp Kengun occurred in a secretive operation that drew criticism from local residents. Protesters gathered outside the camp, voicing concerns about the lack of transparency and the potential for escalating tensions . Kumamoto Governor Takashi Kimura expressed disappointment that the prefecture was not informed about the deployment prior to media reports .

Future Deployments and Policy Shifts

Following the deployment at Camp Kengun, the missiles will be stationed at Camp Fuji in Shizuoka Prefecture, west of Tokyo, later this year . Japan is also considering further bolstering its military capabilities, including the development of unmanned combat weapons and long-range missiles.

Prime Minister Sanae Takaichi has suggested that Chinese military action against Taiwan could warrant a Japanese military response, a stance that reflects a growing willingness to assert Japan’s security interests . The government is also preparing to lift restrictions on arms exports to foster domestic defense industry growth and international cooperation .
