President of the 129th Annual Meeting of the Japanese Ophthalmological Society (JOS2025)

Every year, two major comprehensive conferences are held in the field of ophthalmology: the Japanese Ophthalmological Society (JOS) Annual Meeting in the spring, and the Japanese Society of Clinical Ophthalmology Annual Meeting in the fall. Since these meetings started to be held in the hybrid format, combining on-site and online participation, the number of registered participants has exceeded 10,000, making them truly large-scale academic events.
This year, together with Congrès Inc., we were in charge of organizing JOS2025. We had previously worked with Congrès Inc. when we hosted a specialized ophthalmology meeting in Niigata, where they served as the secretariat. Furthermore, having managed the JOS Annual Meeting last year and the year before, from the moment it was decided three years ago that we would host this meeting, we had hoped to work with them again.
Indeed, with over 10,000 participants, the scale of the program and budget was extraordinary. It was undoubtedly thanks to the strong support from everyone involved in the operation that we were able to successfully conclude the event.
What made working with Congrès Inc. so comfortable was that their instructions and questions were always appropriate and precise, as well as their responses to our requests were swift. For JOS2025, one of our key policies was to incorporate as many ideas from various stakeholders as possible and to try new things. Drawing on their extensive experience organizing a wide range of events and academic conferences, Congrès Inc. offered many valuable suggestions, for which we are truly grateful.
Moreover, the on-site operations on the day of the event was flawless, which again impressed me greatly. Thanks to this, we were able to focus entirely on the academic aspects of the meeting, allowing us to learn and enjoy the event alongside all the participants.
I also heard that for some of the young new employees, this was their first experience working on-site at a medical conference. Nevertheless, each of them contributed to the conference operations with professionalism and care.
Having participated in numerous medical conferences over the years, I am convinced that science and scholarship advance through these kinds of gatherings. Congrès Inc. plays a vital role in supporting this process, and it is fair to say they fulfill an important function in society.
Finally, I would like to extend my heartfelt gratitude to everyone who participated in this academic meeting and to all those who supported us, including the venue staff.

The 89th Annual Scientific Meeting of the Japanese Circulation Society (JCS2025)
Toyoaki Murohara, M.D., Ph.D., FJCS.
Congress Chairperson of the 89th Annual Scientific Meeting of the Japanese Circulation Society (JCS2025)
Professor and Chairperson, Department of Cardiology, Nagoya University Graduate School of Medicine, Nagoya
In line with the main theme of JCS2025, “We Love Cardiovascular (CV) Science”, I personally came up with the initial concept for the conference logo, which was then beautifully finalized by the team at Congrès Inc.
For the special lecture — one of the highlights of the conference — we focused on “disasters,” particularly earthquake and tsunami disasters as a subtheme. We invited Professor Nobuo Fukuwa (Nagoya University), a leading authority in earthquake engineering and disaster prevention who frequently appears in the media, to deliver a lecture and conduct an evacuation drill simulation. The drill was broadcast simultaneously on screens across all venues. To the best of my knowledge, this was the first time a disaster drill was held during a large-scale medical conference, including the Annual Scientific Meeting of the Japanese Circulation Society.
Although Nagoya University, as the hosting institution, organized this year’s conference in Yokohama, which presented numerous challenges, the dedicated support from everyone at Congrès Inc. made it possible to overcome these difficulties and successfully hold the event. From early on, we envisioned running the conference with consideration for SDGs: minimizing food waste from luncheon seminar boxed meals, issuing participant badges without using plastic name card holders, and arranging the program schedule and venue layout so that attendees would have time and space to visit both the exhibition booths and poster sessions. Thanks to Congrès Inc.’s flexibly in responding to various detailed requests up to the event, I am proud to say we were able to hold an outstanding conference. Welcoming over 20,000 registered participants and more than 14,000 attendees onsite was truly a humbling and gratifying achievement.
Additionally, the public lecture for citizens held one week before the conference was also a great success, and I would like to express my sincere gratitude to everyone at Congrès Inc. who supported us.
In closing, I wish you all continued growth and success. Thank you very much for everything.

The 37th Annual Meeting of the Japanese Society for Radiation Oncology
Hiroshi Onishi, M.D., Ph.D.
President
The 37th Annual Meeting of the Japanese Society for Radiation Oncology
Professor, Yamanashi University, Faculty of Medicine, Department of Radiology
The vision we set for this academic congress was clear: to create “a bold and innovative conference that broke conventional norms—one to be remembered and recorded as truly legendary.” To achieve this, we introduced a range of novel initiatives, including debate sessions with live audience voting, daily recognition of the most active questioners, real-time evaluations and awards for on-the-spot presentations, a digital stamp rally in the exhibition area, and even the installation of trick art photo zones.
Some of these ideas were first-time challenges even for a major professional operator like Congrès Inc., and I am aware that many aspects required extraordinary effort and coordination. Despite this, the meeting welcomed a record number of participants, and afterward, we received an outpouring of positive feedback from both attendees and industry partners—many saying things like, “It was an incredibly unique and excellent conference unlike any we’ve experienced before.”
I would like to express my sincere gratitude to Ms. Fujisawa, Mr. Shibuya, Ms. Takeuchi, and Mr. Kato for their exceptional dedication. As the congress approached and new challenges surfaced daily, they responded to every request—no matter how demanding—without complaint and with unwavering commitment. Their presence throughout the event provided a strong sense of security and partnership.
I was especially moved by a heartfelt comment from Ms. Fujisawa immediately after the closing ceremony. She said, “It was tough, but this experience will be invaluable moving forward,” and her expression carried a satisfied smile that stayed with me.
The impression I hold of Congrès Inc. is one of integrity, wholeheartedness, and reassurance. Their contribution went far beyond a typical contractual relationship between organizer and operations team. I am deeply grateful for their partnership. Thank you all, sincerely.

The 62nd Annual Meeting of Japan Society of Clinical Oncology (JSCO 2024)
Toshiyoshi Fujiwara, M.D., Ph.D.
Congress Chairman of the 62nd Annual Meeting of the Japan Society of Clinical Oncology
Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine
The Japan Society of Clinical Oncology (JSCO) is one of the largest medical conferences in the cancer field, where members from various professions come together across medical specialties. At this conference, I saw participants enthusiastically engaging in the program, interacting, and having discussions, and I truly felt that the efforts made by our department and Congrès Inc. in preparing for the event together had borne fruit. Additionally, as the chairman, it was truly gratifying to see that participants fully enjoyed the culture and attractions of the host city, Fukuoka, and that the conference was very well received.
Moreover, at the social events and exhibition spaces, we were able to showcase the charm of Okayama while in Fukuoka, which felt like a way of giving back to the local community that has always supported us. This was also made possible thanks to the experienced team at Congrès Inc., who creatively designed the stage decorations and smoothly facilitated collaboration with the local tourism association. I also saw participants engaging in friendly exchanges, and I feel that we were able to contribute to their refreshment and immune system boost as they face the challenge of cancer.
Not only during the preparation phase but also throughout the conference, I was deeply impressed by how quickly they responded to even the most difficult requests, saying they would take care of them immediately and truly following through. When I stood in front of the wonderful JSCO2024 photo spot with the view of Hakata Port, I once again realized that this conference could not have been held without the cooperation of everyone at Congrès Inc. I would like to express my heartfelt gratitude to all those who participated in this medical meeting and to everyone who helped with the venue and other aspects.
