We extend our sincere appreciation to all of our delegates, speakers, sponsors, community partners, volunteers, and attendees who helped make this year’s Summit a meaningful and successful gathering.

We were honored to welcome participants from our sister states and cities across Japan, including governors, mayors, government officials, business leaders, educators, and community members. Your presence helped foster valuable conversations, strengthen partnerships, and deepen connections across the Pacific.

Thank you for your continued support of the Japan-America Society of Hawaii and our shared commitment to strengthening understanding, friendship, and cooperation between Hawaiʻi and Japan.

ABOUT THE SISTER-STATE & SISTER-CITY PROGRAMS

Sister-State and Sister-City programs harness the power of people-to-people and government-to-government relationships to transform goodwill into meaningful, long-term collaboration. By creating trusted platforms for economic exchange, educational partnerships, cultural understanding, and policy dialogue, these programs enable states, prefectures, cities, and communities to share solutions, unlock new opportunities, and respond collectively to shared challenges. When actively nurtured, Sister relationships become strategic assets—strengthening local economies, deepening mutual respect, and reinforcing international ties that endure across generations and political cycles.
