Editor's Note: Japan is expanding its security role across the Asia-Pacific, raising new questions about regional stability and strategic balance. Is this a natural response to changing conditions, or a deliberate effort to reshape the regional order? What risks could this shift bring for neighboring countries? In this edition of The Hub, the experts explore Japan's recent diplomatic and defense outreach, discuss changes to arms export policies, and examine how regional partners are responding. They delve into the historical context behind today's security dynamics, look into domestic political drivers in Japan, and assess the broader implications for China-Japan relations and the future of peace and stability in the Asia-Pacific.

Will Takaichi ever replicate that gesture at the Memorial Hall of the Victims in the Nanjing Massacre?
