Join us this Friday, October 2nd for a beautiful evening rooted in resilience, honoring Hiroshima’s survivor trees and the Japanese harvest moon viewing tradition of Otsukimi.

Starting at 3pm we kick off with our dedication ceremony as one of our San Diego unified School District schools receives a Ginko Tree that survived the bombing of Hiroshima. We will be honoring members of the community and creating a living legacy at Crown Point Junior Music Academy.

Then at 4pm we will begin Otsukimi, a family friendly festival filled celebrating Japanese culture. Otsukimi (お月見), or “moon viewing,” is a cherished Japanese tradition celebrating the autumn harvest moon. With deep roots in ancient agricultural practices, the festival honors the moon’s crucial light for successful harvests and reflects a deep cultural reverence for nature’s cycles. During Otsukimi, families gather to admire the full moon, decorate with pampas grass (susuki) which symbolizes protection and the harvest, and share seasonal foods like tsukimi dango (rice dumplings). This tradition embodies the Japanese aesthetic of finding harmony with the seasons, inviting participants to pause, appreciate the natural world, and reflect on humanity’s connection to the earth.

Family-Friendly Festivities Featuring:

🌸Cultural Crafts & Cuisine: Enjoy traditional Japanese seasonal foods and shop from local vendors.

🥁Live Performances: Experience the powerful rhythms of taiko drumming and the communal joy of Bon Odori dancing.

🎤Artistic Expression: Watch pop idol, sumo demonstrations and traditional performances by local artists.

🌕Moon Viewing: Take in the magic of our beautiful moon by super powered telescope.

Trees for Peace: A Living Legacy of Friendship Takes Root at Crown Point

Join us on Friday, October 2 for a historic moment as Crown Point Junior Music Academy receives a ginkgo tree grown from a hibakujumoku, one of the trees that survived the 1945 atomic bombing of Hiroshima.

Through the Trees for Peace program, these living descendants are planted in communities around the world as powerful symbols of peace, resilience, remembrance, and hope for future generations.

Event Details
Date: Friday, October 2, 2026
Time: 3:00–4:00 p.m.
Location: Crown Point Junior Music Academy
1625 Pacific Beach Drive, San Diego, CA 92109

What is Trees for Peace?
Trees for Peace brings seeds and saplings descended from Hiroshima’s survivor trees to San Diego schools and community institutions, creating living opportunities to teach about peace, history, environmental stewardship, and plant science.

Participating schools help nurture species including ginkgo, Chinese parasol, wisteria, and camphor, connecting students directly with the history these remarkable trees represent.

The program is organized by SD-WISH in partnership with Green Legacy Hiroshima, San Diego Botanic Garden, San Diego-Yokohama Sister City Society, Japanese Friendship Garden & Museum, and local schools.

The October 2 ceremony will also recognize the community history surrounding Crown Point’s friendship garden, including the contributions of the late Frederic Hewett, an SD-WISH board member who helped establish the garden years ago alongside the school community following the passing of PTO President Raul Cadena.

Following the ceremony, everyone is invited to stay for Otsukimi, the Moon Viewing Festival, from 4:00–8:00 p.m., celebrating Japanese culture, friendship, and community.

The San Diego-Yokohama Sister City Society is heartbroken by the loss of Frederic Hewett, a dear friend and an important part of our Society's history.

Frederic played an instrumental role in rebuilding and strengthening our organization. He had a remarkable gift for bringing people together and turning those relationships into programs and partnerships that continue today.

Frederic’s connection to Japan began long before his work with our Society. His fascination with Japan and its people began in high school and continued throughout his life. A proud graduate of the University of California, Irvine, he also spent a year studying at Hitotsubashi University in Japan. His appreciation for Japanese culture extended beyond academics. Frederic studied the traditional art of Noh theatre and dance under the guidance of a highly respected Noh teacher, an experience that reflected his genuine curiosity and deep respect for Japanese culture.

In 2014, Frederic further deepened that connection while serving as an intern with the TOMODACHI Initiative at the U.S. Embassy in Tokyo, supporting efforts that brought together young people, educators, business leaders, and government through U.S.-Japan exchange. During that time, he also became an important connection on the ground for the San Diego-Yokohama Sister City Society, helping support meetings and relationships that would contribute to the educational exchanges he later championed.

When Frederic returned to San Diego, that commitment continued.

His contributions touched nearly every part of our mission. He worked alongside Eddie Park to help reestablish our educational exchanges with Yokohama; joined Manami Nakayama in creating San Diego’s Seijinshiki with Azuna-kai; helped bring us together with Dr. Mitsuo Tomita and the Japanese American Citizens League for Otsukimi; and introduced the Society to Walter Ritter and Write Out Loud, later joining us for World Kamishibai Day.

Frederic was the architect behind the Raul Cadena Friendship Garden at Crown Point Junior Music Academy, bringing together the people and partners who made it possible. That project would later help inspire our Trees for Peace partnership with SD-WISH. This past year, Frederic joined the Board of SD-WISH, continuing his commitment to peace and friendship.

Across the Pacific, Frederic helped establish the opportunity for the Mission Bay Jazz Preservationists to perform at Sankeien Garden in Yokohama, which became a signature event of our Ambassadorial Goodwill Tours. The band performed there in 2017, 2019, 2023 and 2025, with their next performance planned for 2027. What began with a connection grew into an enduring tradition of friendship between San Diego and Yokohama.

Most recently, Frederic was once again giving his time and energy to our efforts to relaunch the House of Japan, helping build the next chapter of a relationship to which he had already given so much.

Frederic believed deeply in the power of people-to-people relationships. In 2019, the Society honored him with our Spirit Award in recognition of his extraordinary service, loyalty, and devotion.

The award included a Japanese proverb that feels especially meaningful today:

塵も積もれば山となる

Chiri mo tsumoreba yama to naru.

Even dust, when accumulated, becomes a mountain.

That was Frederic. Countless acts of kindness, service, introductions, and friendship accumulated over the years into something far greater than any single act.

The San Diego-Yokohama Sister City Society that exists today carries Frederic's impact throughout it, as does our broader San Diego sister-city community. His legacy lives in the programs he helped create, the partnerships he helped establish, and, most importantly, the people he brought together, whose own work and relationships have continued to strengthen our community in ways Frederic could never have imagined.

We extend our deepest condolences to Frederic's family, friends, students, colleagues, and everyone whose life he touched.

Frederic will forever remain part of the San Diego-Yokohama Sister City Society family, our history, and the friendship between San Diego and Yokohama.

With gratitude and love,
San Diego-Yokohama Sister City Society

VOLUNTEERS NEEDED – Help Paint San Diego History

From July 12–19, the community is coming together to help create a mural celebrating the Black and Chicano musical legacy of Imperial Avenue.

For generations, Imperial Avenue was one of San Diego's most important cultural and musical corridors—a place where Black and Chicano musicians, artists, activists, and community leaders helped shape the city's history.

Today, we're bringing those stories back to life.

The Imperial Avenue Music History Legacy Project is creating a community mural that celebrates the people, places, and music that made this neighborhood legendary—and you can help paint it.

Volunteer Days
July 12–19, 2026
10:00 AM – 6:00 PM

Barrio Guetto Gallery
2741 Imperial Ave.
San Diego, CA 92102

Community Activation Music Day
Saturday, July 18 | 2:00–6:00 PM

Join us at the Elks Lodge to hear firsthand stories from community elders about the music, activism, and cultural history of Imperial Avenue.

This mural is more than public art—it's a community effort to preserve and celebrate an important chapter of San Diego's history for future generations.
