Japan’s Commitment to Defense Partnership with the U.S. Amid Cybersecurity Concerns

Japan’s Commitment to Defense Partnership with U.S. Hindered by Cyber Vulnerabilities

As the United States grapples with security threats worldwide, Japan has pledged to strengthen its role as a trusted defense partner. However, concerns linger over Tokyo’s cyber and information security vulnerabilities, officials and experts warn.

Japanese Prime Minister Fumio Kishida recently assured the U.S. Congress of Japan’s commitment to supporting its ally in countering challenges posed by Russia’s actions in Ukraine and China’s growing assertiveness. The two nations have also expanded their military cooperation, exploring opportunities to enhance defense production and develop new technologies with AUKUS partners Australia and Britain.

Despite these efforts, Japan has been the target of high-profile cyberattacks in recent years, impacting critical infrastructure and government institutions. These incidents have raised doubts about Tokyo’s ability to fully support its security partners in the face of evolving threats.

Mark Manantan, director of cybersecurity at the Pacific Forum think tank, described Japan’s cybersecurity vulnerabilities as a longstanding concern for both Japan and the U.S. The country faces challenges in building robust defense systems and recruiting skilled personnel to address these vulnerabilities.

Former U.S. Director of National Intelligence Dennis Blair highlighted Japan’s weak cyber defenses as a significant liability in the security alliance between the two nations. While Japan has announced plans to bolster its cyber capabilities by increasing its cyber defense force, recruitment efforts have faced obstacles such as competition for talent and attractive salaries in the private sector.

Japan’s Defense Ministry aims to double its defense spending over five years and quadruple its core cyber defense force. However, meeting recruitment targets remains a challenge due to the shortage of cybersecurity professionals in the country.

The government has proposed measures to attract cyber talent, including offering competitive salaries and easing physical fitness requirements. Despite these efforts, recruiting and retaining skilled personnel in the cybersecurity field remains a hurdle for Japan.

In addition to enhancing its cyber capabilities, Japan is seeking to preemptively detect and neutralize cyber threats. However, legal amendments required to authorize such actions have yet to be submitted to parliament, citing constitutional constraints on the use of force.

While Japan has relaxed rules on defense exports to facilitate international collaboration, bureaucratic hurdles and a lack of a robust system for handling classified information have complicated defense projects with overseas partners. Efforts to streamline these processes through legislation may take several years to materialize.

As Japan navigates these challenges and strengthens its defense industry, experts caution that the country’s security apparatus may not be ready to fully integrate into Western security projects like AUKUS. Despite Japan’s commitment to enhancing its defense capabilities, addressing cybersecurity vulnerabilities remains a critical priority for the country’s defense partnership with the United States.
