  • About the Program

    The Allied Security Practitioners’ Exchange Network (ASPEN) is a program designed to build a cohort of Alliance Security professionals who share trusted social bonds forged by common professional development experiences. The ASPEN initiative aims to provide the foundation and forum necessary to foster a culture of growth and collaboration through a series of workshops and social events in Japan.

    Membership is open to Japanese and American security professionals with at least 3 years of experience. This includes government officials, military/SDF officers, coast guard officers, police, employees of defense industries, defense contractors, and security-focused academics. Junior- to mid-grade professionals are especially welcome. Participation will be in personal capacity. Membership is free, but individuals will need to register via an online form.
