I am delighted to announce that the 84th Annual Meeting of the Japan Neurosurgical Society will be held from October 29 to November 1, 2025 at Pacifico Yokohama, in Yokohama, Japan. It is a great honor to have been given this opportunity to host the Annual Meeting.

The theme of this Annual Meeting will be “Neurosurgeons’ Quest: Exploring the Unknown.” As technological innovations are accelerating in every field, the world in which we live now was unimaginable just a few decades ago. Flexible thinking and a can-do attitude will both be required if we are to build the future of neurosurgery without relying solely on what has come before. Even in the midst of these drastic changes, however, what is most important for us as physicians is care and consideration when treating each individual patient. Our desire to respond to the entreaties of patients suffering from intractable diseases is the driving force for medical advances. As we are generally immersed in our daily practice as neurosurgeons, it is with the intention of giving us the opportunity to pause and ask ourselves what we should be doing with a view to our future that I have chosen the theme of “Neurosurgeons’ Quest.”

Following the recent integration of information sciences, the life sciences are undergoing a paradigm shift. Collaboration and cooperation with other disciplines will be essential for the further development of neurosurgery. We are planning sessions at the Annual Meeting to bring these new cross-disciplinary perspectives to the fore and to energize us for the quest ahead. We will demonstrate the multifaceted activities of neurosurgery in an attractive way to the young doctors who will take over from us in the near future, and we will host discussions about the future of neurosurgery from these various perspectives. In this era of increasing internationalization, I also believe we must discuss how we can disseminate our discoveries from Japan to the world and the variety of ways that we can be world leaders in the field.

The Annual Meeting will be held jointly with the 2025 Satellite Symposium on Schwannoma Predisposition Syndromes: Neurofibromatosis Type 2/Schwannomatosis. It will be the first time that such a symposium has been held in Asia. In particular, the frameworks for the research and treatment of these intractable rare diseases are undergoing great changes, and I hope that the symposium will be informative and impactful for attendees.

We are making every effort to ensure that this will be a highly fruitful Annual Meeting. I look forward to seeing many of you there.
