Greetings, from The Japanese Society of Chronobiology

(President of the JSC)

About JSC
The Japanese Society for Chronobiology (JSC) was established in 1994 after a long-term discussion among basic scientists and medical doctors from two preceding research communities, Japan Biological Rhythms Group (1984-1993) and Japan Clinical Chronobiology Group (1986-1993). By integrating these two communities, the JSC was newly established and is now dedicated to promoting scientific researches on biological rhythms of all living organisms, to stimulate the development of chronobiology, and to contribute to health and welfare of human beings by socially distributing the results of our activities. The JSC publishes “Journal of Chronobiology” (two issues per year, in Japanese), which gathers reviews from a variety of research fields, reports on recent meetings, greetings from laboratories, and a variety of news and comments, submitted from all generations of the researchers. Now, the membership of the JSC is more than 600 and it is characterized by an increasing number of younger generations. The most recent 28th Annual Congress JSC 2021 (Nov. 20-21) was held in a southern island Okinawa, with 378 attendees, 124 poster presentations, six symposia, two special lectures, and two young awardee lectures. A one-day meeting is also organized by young investigators every year, often in conjunction with the JSC Annual Congress.

History of JSC
The JSC was established in 1994 by integration of two preceding research communities, Japan Biological Rhythms Group and Japan Clinical Chronobiology Group. In 1983, Prof. Franz Halberg (Minnesota University, USA) sent a message to Prof. Kentaro Takagi (Nagoya University) and Prof. Koichi Kawasaki (Kyushu University), expecting Japanese chronobiologists to organize an international meeting on chronobiology in Japan. This message from Prof. Halberg triggered organization of Japan Biological Rhythms Group led by Prof. Takagi. The first research meeting was held in 1984 (Aichi), to which 62 chronobiology researchers attended. Since then, ten annual research meetings had been held until 1993, in which topics of the presentations were distributed across a wide range of biological organisms. On the other hand, Japan Clinical Chronobiology Group was established by Prof. Kiyohisa Takahashi (National Center of Neurology and Psychiatry), Prof. Ken-ichi Honma (Hokkaido University) and Prof. Shiro Endo (Psychiatric Research Institute of Tokyo), and their major interests were focused on biological rhythms of humans. The first research meeting was held in 1986 (Tokyo) with 30 attendees under a support by Honma Foundation. Since then, eight annual meetings had been held until 1993 (six times in Tokyo). During these activities, the researchers in the two communities, Japan Biological Rhythms Group and Japan Clinical Chronobiology Group, interacted with each other, and sometimes a joint symposium was organized in the meeting. Finally, we decided to join to formulate a new and more broad research association of biological rhythms, the JSC, in 1994. After several changes in operating system of the early JSC, Prof. Kiyohisa Takahashi (National Center of Neurology and Psychiatry) was elected as the first president of the JSC (2002-2004), Prof. Ken-ichi Honma (Hokkaido University) as the second president (2005-2010), Prof. Takao Kondo (Nagoya University) as the third president (2011-2016), and Yoshitaka Fukada (University of Tokyo) as the fourth president (2017-2022).

UUnder a ‘Memorandum of Understanding’ (MOU) between the European Biological Rhythms Society (EBRS, represented by Prof. Martha Merrow) and the Japanese Society for Chronobiology (JSC, represented by Yoshitaka Fukada), we agreed to reciprocal arrangements which welcome members of both societies to attend EBRS or JSC meetings and other events at the member rates published by the host society. We hope this MOU functions to improve exchange and to increase collaborations between scientists from our societies.
