There are more than a hundred psychiatric societies due to the wide range of psychiatry and the variety of subjects and problem-solving approaches. At the 115th Annual Meeting, I focused on the fact that the Society plays an important role as a core academic society, and sought to find a way for experts in a wide range of fields to participate with a "mind of proactive involvement."
 The theme of this meeting is "Psychiatry to bridge human, mind, and brain: Beyond time and current matters. In Japanese "toki" of the "toki-wo koete" (beyond time) has multiple meanings, such as time, unlocking secrets and the name of the Japanese crested ibis. It is infused with a message that signifies an unraveling of the mysteries of the functions and afflictions of the heart and mind, moving beyond the crested ibis, the symbol of Niigata. We take it for granted that people exist in a biopsychosocial realm. In addition to people's existence as biological entities, we also have a psychological presence complete with a complex mind, our greatest features that differentiate us from other creatures. We form an extremely complex society, where we can share "meaning" and "information" by acquiring the ability to shift from a "sense of recognizing differences" to "recognizing similarities by closing our eyes to differences(assimilation)" and where we emphasize the importance of this pursuit. As social beings, people influence society, while also simultaneously being greatly affected by society. As experts, we develop responses to medical issues that appear in the "mind". However, in order for us to properly deal with problems of the "mind", we must understand this phenomenon well and enrich our understanding of the functions of the "brain", which forms this base. It is extraordinarily difficult to shed light on this phenomenon, but we must move beyond. I wish psychiatry focused more on each "person" as a whole and not as a reductive understanding and connected the "mind" and "brain" with the "person" playing a leading role, trying to aim at medical care with an understanding of that person's life experiences and value.
 Based on this feeling, in the Chairman's lecture, I first outlined the progress of psychiatry and the transition of psychiatric diagnostics over the past two centuries. The introduction of the international diagnostic system is said to have improved the reliability and have promoted the progress of treatment and biological research. On the other hand, there is an increasing lack of recognition that the current system is only a tentative one in the process of development. I discussed the problem of poor understanding of symptoms and diseases and proposed measures to improve them.
 Various findings that elucidate the etiology and pathology of mental illnesses have been reported to deepen its understanding. However, the understanding of the connection between all the levels starting from the genetic level to the functions of the mind is not sufficient. I believe that the understanding of such a multi-layered system that forms the "mind" is most important in the 21st-century psychiatry.
 Next, advances in psychiatric treatment have brought about standardization and optimization of drugs and psychosocial treatments, enabling many patients to live in society, while the QOL reduction and physical risk due to side effects of drug therapy have drawn attention. I introduced the increasing related evidence regarding this issue.
 The progress of medical treatment has also brought about changes in medical needs. The importance of considering the future psychiatric medical care system based on accurate prediction and the importance of developing psychiatry in connection with society were pointed out.
