Tokyo – Japan has taken a significant step in bolstering its defense capabilities with the confirmed deployment of its first domestically produced long-range standoff missiles. The move, announced Tuesday by the Ground Self-Defense Force (JGSDF), marks a pivotal shift in Japan’s defense posture, enabling a counterstrike capability long debated within the country and prompted by escalating regional tensions. This development in Japan’s missile defense is a direct response to perceived threats from North Korea and China.
The newly deployed systems, designated the Type-25 surface-to-ship missile and the Type-25 hyper velocity gliding projectile (HVGP), were previously known as upgraded versions of the Type-12 surface-to-ship guided missile and the island defense high-speed gliding projectile. According to the JGSDF, both systems have completed development and are now operational with active units. This represents a substantial advancement in Japan’s ability to deter potential aggressors and respond to evolving security challenges in the Indo-Pacific region.
Responding to a Changing Security Landscape
Japan’s decision to develop and deploy these long-range missiles is rooted in a growing assessment of the security environment surrounding the nation. The Defense Ministry has consistently highlighted increasing concerns over China’s military expansion and North Korea’s continued ballistic missile development and testing. These factors, coupled with ongoing instability in the region, prompted a reevaluation of Japan’s traditionally defense-oriented security policy.
The Type-25 surface-to-ship missile has been deployed to Camp Kengun in Kumamoto Prefecture, while the Type-25 HVGP is stationed at Camp Fuji near Gotemba in Shizuoka Prefecture. The missiles are designed to target both maritime and land-based threats from a distance, providing Japan with a crucial layer of defense. Reports indicate the Type-25 missile boasts a range of approximately 1,000 kilometers, while the HVGP, utilizing a hypersonic glide vehicle, can travel hundreds of kilometers at supersonic speeds, making interception significantly more tricky. The irregular flight paths of the HVGP are specifically designed to evade existing missile defense systems, enhancing its survivability.
A Shift in Postwar Doctrine
This deployment is directly linked to Japan’s revised 2022 National Security Strategy, a landmark document that formally acknowledged the need for counterstrike capabilities. For decades, Japan’s postwar constitution and security policies prioritized a defensive posture, limiting its ability to project power beyond its borders. The 2022 strategy signaled a significant departure from this approach, recognizing the necessity of deterring potential adversaries by demonstrating the ability to respond to attacks on Japanese territory. This shift reflects a broader trend in the region, with countries like Australia and South Korea also strengthening their defense capabilities in response to regional challenges.
The development of these missiles isn’t happening in isolation. Japan recently completed modifications to the Aegis destroyer Chokai, enabling it to launch U.S.-made Tomahawk cruise missiles. This further expands Tokyo’s long-range strike options, creating a multi-layered defense architecture that includes ground-launched domestic systems, ship-launched cruise missiles, and planned future air-launched variants expected by 2027. This integrated approach aims to provide Japan with a comprehensive and resilient defense system.
Regional Implications and Concerns
The increased range of Japan’s strike capabilities has significant implications for regional security dynamics. With a range of 1,000 kilometers, the Type-25 missile places parts of China’s coastline, the East China Sea, and nearly all of North Korea within potential reach from existing deployment sites. This capability is intended to deter potential aggression by raising the cost of any attack on Japan. However, it also raises concerns about potential escalation and the possibility of a regional arms race.
China has consistently expressed opposition to Japan’s growing military capabilities, viewing them as a threat to regional stability. The Chinese Foreign Ministry has repeatedly urged Japan to adhere to its pacifist constitution and refrain from actions that could escalate tensions. North Korea has similarly condemned Japan’s military buildup, accusing it of being part of a U.S.-led effort to contain the country. These reactions underscore the sensitivity surrounding Japan’s defense policies and the potential for miscalculation in the region.
The deployment of these missiles also comes amid heightened tensions surrounding Taiwan. Japan has expressed growing concern over China’s military activities near Taiwan and has reaffirmed its commitment to maintaining peace and stability in the region. The ability to strike targets in the East China Sea could provide Japan with a greater capacity to respond to any contingency involving Taiwan, further complicating the geopolitical landscape.
Looking ahead, Japan is expected to continue investing in its defense capabilities, focusing on areas such as cybersecurity, space-based assets, and unmanned systems. The government is also likely to strengthen its alliances with the United States and other like-minded countries in the region. The next key development will be the implementation of the planned air-launched standoff missile variants by 2027, further solidifying Japan’s position as a major military power in the Indo-Pacific.
