Executive Leadership Profiles
Lisa Christy, Co-CEO
Lisa Christy is a specialist in understanding audiences and how best to communicate with them. She is the Co-CEO of Portland Japanese Garden, serving alongside Aki Nakanishi to guide the organization into its next era of cultural leadership, community partnership, and global exchange. She joined the Garden in 2014 as Director of Marketing & Communications at a pivotal moment, just as the Garden embarked on its historic Cultural Crossing expansion designed by Kengo Kuma. Lisa later served as Chief External Affairs Officer and then Executive Director before being appointed Co-CEO in 2026.
Lisa’s approach to leadership is rooted in her early life in the arts. Trained as a classical pianist on the path toward a concert career, she developed a deep appreciation for discipline, nuance, and how emotion is communicated without words. Ultimately, she realized that her true passion was understanding how people connect: what moves them, what inspires them, and what opens the door to belonging. That realization led her to communications, and it remains the foundation of her work today. She carries this forward in leadership, guided by the philosophy: “If you want to go fast, go alone. If you want to go far, go together.”
Throughout her tenure, Lisa has helped define how Portland Japanese Garden serves its community. She led a sevenfold expansion of the External Affairs division, oversaw a comprehensive rebrand, and directed the communications strategy for the Cultural Village opening, earning national and international recognition. She built the Garden’s guest experience strategy, expanded community access and engagement programs, and helped drive record-setting membership and attendance year after year.
Prior to joining Portland Japanese Garden, Lisa spent nearly a decade at advertising agency Wieden + Kennedy, helping to guide to some of the most influential and award-winning campaigns of the past 20 years, including Old Spice’s “The Man Your Man Could Smell Like” and Procter & Gamble’s “Thank You, Mom” Olympic campaign, as well as work for Sony, Starbucks, and Travel Oregon. Her travels to Japan on Sony campaigns, combined with tourism work for Travel Oregon, led her to her dream role at Portland Japanese Garden. Earlier in her career, she worked at agencies in Minneapolis and Kansas City.
A committed mentor and advocate for education, Lisa spent three years as a full-time adjunct professor at the University of Tennessee, where she was named Lecturer of the Year. She continues to speak to universities, professional groups, and community organizations. She holds a bachelor’s degree in communications from Middle Tennessee State University and a master’s in advertising from Michigan State University.
Lisa lives in Portland with her husband and their teenage son who keeps his mom and dad busy with his many, many, many baseball games.
Aki Nakanishi, Co-CEO & Arlene Schnitzer Curator of Culture, Art, and Education

Aki Nakanishi is an international cultural leader and public diplomacy expert with nearly three decades of experience in government relations, public communication, cultural programming, and artistic exchange. He has built a distinguished career conceptualizing and delivering impactful initiatives for global audiences, and currently serves as Co-CEO of Portland Japanese Garden alongside Lisa Christy. In addition, he is the Arlene Schnitzer Curator of Culture, Art, and Education, guiding the organization’s cultural vision, international/national partnerships, and multidisciplinary programming. Prior to being appointed Co-CEO, he also served as Director of Japan Institute, the Garden’s cultural and programmatic arm.
In his previous capacity at Portland Japanese Garden, Nakanishi led more than 1,000 programmatic initiatives that advanced the organization’s stature as a leading force in cultural diplomacy. These initiatives encompassed art exhibitions, seasonal festivals, cultural demonstrations, workshops, seminars, lectures, concerts, international conferences, and culinary programs. Through a strategic vision that bridged local and international engagement, Nakanishi deepened the Garden’s network of partners and supporters across Japan and the U.S., helping to elevate Portland’s profile on both sides of the Pacific, a city that he and his family now proudly call home.
Prior to relocating from Tokyo in 2018, Nakanishi spent a decade as the Cultural Affairs Specialist at the United States Embassy in Tokyo. In this role, he oversaw a broad portfolio of cultural, creative, and educational engagements designed to deepen mutual understanding between the U.S. and Japan. As principal advisor to the Embassy’s Cultural Attaché and a key cultural advisor to multiple U.S. Ambassadors, he played a central role in shaping the Mission’s cultural diplomacy strategies. His portfolio included direct oversight of high-profile initiatives such as Ties Over Time under Ambassador John V. Roos and the International Poetry Exchange Project under Ambassador Caroline B. Kennedy, each of which strengthened long-term people-to-people connections through art and education.
Alongside the Embassy duties, Nakanishi pursued his own creative career as an independent artistic director. He spearheaded the creation of large-scale exhibitions and art fairs including Art Photo Tokyo 2016-17, and the Tokyo International Literary Festival from 2012-18. He has also contributed extensively to arts publications, written dossiers for cultural events, and founded his own non-profit organization, echovisions, dedicated to regional revitalization and youth empowerment.
For his achievements at the U.S. Embassy, Nakanishi received multiple State Department distinctions, including the Meritorious Honor Award (2010), the U.S. Embassy Japan Eagle Award (2011), and the U.S. Mission Japan Honor Award (2016).
Nakanishi’s career began in mass media as Program Director at one of Japan’s major television networks, where he honed his skills in public communication, program development, and audience engagement. He later embarked upon the contemporary art world to gain a deeper understanding of human creativity and visional curation, working as an art dealer to connect budding artistic talents with the world.
He holds a master’s degree in Cultural Policy from the National Graduate Institute for Policy Studies (Japan) and is currently a PhD Candidate at the University of Cambridge (UK), where his research explores cultural intermediaries and artistic networks in medieval Japan.
