The RIKEN International Symposium was held successfully!
We would like to thank all the speakers, poster presenters, and participants for their invaluable contributions in making the symposium successful. We are also grateful to them for joining us in celebrating Dr. Naoko Imamoto's retirement from RIKEN.


At this symposium, leading experts in the nucleus and chromatin/chromosome fields will exchange exciting new findings and ideas.

The nucleus is the most prominent structure in eukaryotic cells, playing an essential role in organizing the genomic DNA as chromatin and contributing to cellular functions. Over the past 20 years, significant advancements in the fields have been made: identification of components of the nucleus and chromatin/chromosome, the development of high-resolution imaging techniques for visualizing their structures in living cells and tissues, high-resolution mapping of genome interactions, in vitro reconstitution of the related supramolecular complexes, and even 3D computational modeling of the nucleus and chromatin/chromosome structures. These revolutionary technologies have greatly advanced our understanding of the nucleus and chromatin/chromosome.

This symposium aims to create a new trend in the fields by promoting the integration of traditional studies based on biochemistry, cell biology, and molecular biology with emerging technologies with "big data" such as super-resolution imaging, genomics, and mathematical modeling. The symposium also aims to share exciting hot topics in the fields with young researchers, encouraging further collaboration, and passing on the legacy of nuclei and chromatin/chromosome research to the next generation researchers.

Words from Dr. Naoko Imamoto

I found myself in the year of my retirement. Because I was immersed in the science for so many years, I can’t not really feel that I am retiring, even as I was preparing for the closing of the lab. On the other hand, I have no hesitation in quitting RIKEN because I plan to return to Osaka first when I retire.

Under such circumstances, Kazuhiro, a former staff scientist of my lab, proposed a symposium to commemorate my retirement. I myself never thought of a symposium for myself, nor did I have a budget in my mind for it! Despite this, many people, including Kazuhiro, kindly supported to prepare the symposium. For example, invited speakers from abroad, who are all very busy people in responsible positions, immediately secured a date and agreed to come to Japan to attend the symposium even we could not offer travel expenses. The planners have prepared as much of their own work as possible due to the small budget. RIKEN and Grant-in-Aid for Transformative Research Areas “Genome modality” kindly co-sponsored the symposium. Truly, I am deeply grateful to all of people.

In a word, I have had a very fortunate and happy life as a researcher so far. I have been supported by many of my lab members, colleagues, seniors, and research friends both in Japan and Abroad. My greatest hope now is that the current lab members will continue to pursue their own satisfying paths after my lab closes.

I will be retiring and leaving RIKEN, but I may have the opportunity to meet you all at some point. I look forward to seeing with you in the future.

With best wishes,

Naoko Imamoto
