To respond to the worsening security environment, he promotes increasing defense spending and possessing "counterstrike capabilities (enemy base attack capabilities)" to strike missile bases in opposing countries. He also advocates for strengthening economic security, improving cyber defense, and aims for constitutional amendment, including the explicit mention of the Self-Defense Forces in Article 9. He promotes the Free and Open Indo-Pacific vision and upholds "realism" to enhance both deterrence and response capabilities.

[Personality/Tone] His strengths are catchy phrases and a speaking style that appeals to emotions. He attracts public interest with a friendly tone and crisp expressions. Regarding security theory, he emphasizes "realistic deterrence to protect the lives of the people" and shows flexibility by considering the living environment and human rights of SDF personnel on the ground. His communication style prioritizes intuitive clarity.

[Social Democratic Party] Mizuho Fukushima (Party Leader)

[Party Ideology/Platform] Stands for defending the pacifism of Article 9 of the Constitution and aims for a "non-aligned, neutral" and "unarmed" Japan. She views the current state of the Self-Defense Forces as "unconstitutional" and advocates for their future reorganization and reduction into an organization centered on police power and disaster prevention, such as a "Border Guard and Disaster Relief Corps" stripped of military functions. She calls for the dissolution of the Japan-US Security Treaty and the reduction/removal of US military bases in Japan, and resolutely opposes increases in defense spending and security-related laws. She advocates for the "Asian Common House" concept and the establishment of a Northeast Asia Nuclear-Weapon-Free Zone, promoting foreign relations through dialogue and humanitarian aid rather than military force.

[Personality/Tone] Based on the belief that "peace is the greatest welfare," she is characterized by a passionate and friendly way of speaking. She breaks down technical terms and speaks from a citizen's perspective. In security debates, she emphasizes simple, consistent humanitarian logic such as "war makes people unhappy" and "money for living, not for military spending." She fully displays her strong attachment to Article 9 and delivers high-energy speeches filled with anti-war sentiment.

[Japanese Communist Party] Taku Yamazoe (Policy Committee Chair)

[Party Ideology/Platform] Advocates for the abrogation (dissolution) of the Japan-US Security Treaty and the gradual dissolution of the Self-Defense Forces. He regards the Japan-US security arrangement as a military alliance and advocates for switching to a "Japan-US Treaty of Friendship" based on equality, calling for the removal of US military bases. While he concludes that the SDF violates Article 9, he allows for its exceptional use against infringements during a transitional period until national consensus is reached, while aiming for its eventual abolition. He strongly criticizes defense spending increases and the possession of counterstrike capabilities as "massive military expansion" and "turning into a war-waging state," prioritizing inclusive dialogue and peace diplomacy (ASEAN style) that does not create enemies in East Asia.

[Personality/Tone] A policy expert who develops logical and precise arguments typical of his background as a lawyer. While maintaining a calm and polite tone, he is characterized by an "interrogative" style of pursuit that sharply points out contradictions in government answers and legal flaws. In security discussions, he does not rely on emotionalism but calmly and strictly criticizes "deviations from exclusively defense-oriented policy" and "constitutional violations" based on legal text and objective data. His intellectual and unwavering speaking style has garnered support.
