Welcome to ISNAC2025 in Toyama!

It is my great pleasure to welcome you all to the 52nd International Symposium on Nucleic Acids Chemistry (ISNAC 2025), which will be held from November 12-14, 2025, at the Toyama International Conference Center in Toyama City, Japan. As the Chair of this symposium, I am honored to host this event, which will bring together researchers and experts from around the world to share the latest advancements in nucleic acid chemistry.

Since its inception in 1973 as a domestic meeting in Japan, ISNAC has evolved into a leading international symposium, promoting collaborations across various disciplines such as organic chemistry, biochemistry, molecular biology, and biotechnology. This year, we continue to expand our scope to include cutting-edge topics such as nucleic acid-based nanotechnology, synthetic biology and therapeutic/diagnostic applications.

Toyama, famous for its scenic beauty, excellence in traditional crafts and historical ties to Japanese Nobel Prize-winning scientists, provides a conducive setting for this gathering. The Toyama International Conference Center, located in the central area of the city, offers a modern and inspiring venue for our discussions and exchanges. We are committed to providing an engaging scientific program featuring distinguished speakers, insightful discussions, and opportunities for collaboration.

On behalf of the organizing committee, I extend a warm invitation to all participants, from students to senior researchers in academia and industry. We look forward to your active participation in making ISNAC 2025 a successful and inspiring event.
We are very much looking forward to seeing you all in Toyama.
