Emeritus member, Japanese Society of Toxicology


 The Japanese Society of Toxicology(JSOT) was founded in the Toxicology Research Group (TRG) and the Toxic Action Research Group (TARG), which were independently created in 1975 and 1976, respectively. TRG membership consisted of veterinarians, while the TARG was geared towards medical and pharmaceutical researchers. In 1981, the two groups merged and the Japanese Society of Toxicological Sciences (JSTS) was founded as a non-profit scientific society. From its inception, the aims of the JSTS have been to promote the acquisition and utilization of knowledge in toxicology and to facilitate the exchange of information among its members, as well as among investigators worldwide. The JSTS was renamed the Japanese Society of Toxicology (JSOT) in 1997. In 2014, the JSOT became a general incorporated association, and it has developed into an organization of nearly 3,000 members.


 In support of the JSOT mission of advancing health through furthering understanding of and research in toxicology, the Society promotes the following activities:

1) Convening the annual meeting
2) Publishing the official journal
3) Educating and certifying toxicologists
4) Conducting scientific and publicity related activities for members and the public.
5) Engaging in other programs/projects deemed necessary to support the JSOT mission.


The JSOT has five recognized member categories: General members, Student members, Honorary members, Meritorious members and Supporting members. JSOT membership, which was 943 at the Society’s founding in 1981, had blossomed to 2598 as of Jan 1, 2020, consisting of 2573 members in Japan and 25 from overseas making it the second largest toxicology society in the world.
Among its current members are 25 associates from around the world, including 9 from USA, 5 from Korea, 9 from the USA, 3 from the UK, 2 each from Switzerland and China, and 1 each from France, Germany, Indonesia and Malaysia. Member affiliations are diverse as well, including industry and contract research organizations (60%), academia (32%), government agencies (3%), and others (5%).

 As of Jan 1, 2020, the JSOT’s managing structure included 19 Directors and 296 Councilors. The Board of Directors meets twice a year to draft the action plans of the JSOT. The Council Meeting and the General Meeting are held once a year to discuss the action plans proposed by the Board of Directors.


 The JSOT has established five strategic Committees to accomplish the Society’s activities.

   Board of Executive Directors (Board of General Affairs)
   Editorial Committee
   Educational Committee
   Financial Committee
   Science and Publicity Committee

General Affairs Committee

 The committee has two major responsibilities. The first is to strategically draw up the JSOT general action plans for the year by reviewing the plans proposed by the individual committees and preparing the subjects for discussion at Board of Directors meetings, the second is to manage JSOT membership, including the nomination and approval of new councilors and members.

Editorial Committee

 The official journal “Journal of Toxicological Sciences (JTS)” (online ISSN: 1880-3989; print ISSN: 0388-1350) was launched in 1981 to provide a dedicated forum for invited review articles and peer reviewed original papers.
 In 2014, a second journal, “Fundamental Toxicological Sciences (Fundam. Toxicol. Sci.)” was launched and the editorial committee has put in place a highly efficient Web-based manuscript submission and peer review system.
 The JTS has invited distinguished toxicologists from throughout the world to become Associate Editors and Editorial Board members. One of the Society’s top strategic priorities is the ongoing development of its journal. The JSOT is in the process of developing a new look and feel for the journal.

Educational Committee

 The main task of Education Committee is to stimulate the advancement of toxicology and improve the quality of toxicologists by sponsoring certification and recertification examinations, continuing education courses, and fundamental education courses. The Fundamental Education Course is held annually in agreement with scope and level of examination, and the Continuing Education Course is also held annually to offer state-of-the art information for toxicologists.
 Since 1995, the JSOT Board of Directors has seriously discussed the accreditation and certification of toxicologists in Japan. After extensive deliberations, the certification program of toxicologists was newly launched in 1997 under the control of the Education Committee. The written examination has been offered every year, and 662 toxicologists have been formally approved as diplomats as of Jan 2020.
 Each applicant must have had a principal involvement in the practice of toxicology, in addition to the appropriate background education. The examination covers all aspects of toxicology and toxicity testing. Certified Toxicologists should have knowledge that encompasses all aspects of toxicology, and should be able to conduct proper toxicological planning, testing, evaluations, and risk assessment (for details, see Item “Accreditation and professional certification program”).

Financial Committee

 The Financial Committee deals with all of the financial issues of the JSOT. The JSOT has continued to make progress in strengthening the financial foundation of the Society. Major steps are being taken to set up and implement a system for monitoring ongoing financial actions and to develop future plans. In addition, the Society has considered modernizing and upgrading the budget and expenditures management process. The JSOT has 47 supporting members, mainly employed in private industries, who have financially supported the achievement of the strategic plans of the Society.

Science and Publicity Committee

 The JSOT has provided public education lectures on toxicology since 1995 at its annual meetings, and in 2006 the JSOT website was redesigned to include links to other toxicology-related websites. Our website also presents updated information in both Japanese and English for its worldwide membership. These activities fall under the auspices of the Science and Publicity Committee. Furthermore, in addition to the Best Paper Awards, each year the JSOT presents other prestigious awards such as the JSOT Award and the JSOT Young Scientist Awards in recognition of distinguished toxicologists, based on the judgment of the Awards Subcommittee, which is organized under the control of the Science and Publicity Committee. Award recipients are honored at a special ceremony at the JSOT annual meeting, and their names are listed in the JSOT publications.

Accreditation and professional certification program

 A JSOT certification program for toxicologists, based on annual closed book examinations, was launched in 1997, with the content and level of examination questions selected to be comparable to those provided by the American Board of Toxicology. At the first DJSOT certification examination in 1999, 148 toxicologists were certified. These 148 certified toxicologists included 47 who passed written examination, and 99 who were “grandfathered” in without written examinations based on their longstanding and significant careers in toxicology.
 As of Feb. 1, 2017, 554 toxicologists have been formally approved. Furthermore, as of Feb. 1, 2017, 47 Emeritus Diplomats of the Japanese Society of Toxicologists (EDJSOT) were certified. Approximately 80% of the Society’s diplomats are from industry, 12% from academia, and 8% from other fields. Diplomats may be recertified every five years provided they remain in active toxicology practice and maintain an expert level of knowledge in general toxicology.

Public education lectures

 To promote public education in toxicology, the JSOT organizes public lectures during each annual meeting. Scientific experts are invited to lectures on popular and important topics related to clinical medicine and drug therapy.


 The JSOT presents several awards to the outstanding toxicologists. The names of the recipients of all awards are shown on the JSOT website. The following lists the current awards sponsored by the Society:

International Union of Toxicology (IUTOX)

 The purpose of the International Union of Toxicology (IUTOX) is to foster international scientific collaboration among national and other groups of toxicologists and to promote worldwide acquisition, dissemination, and utilization of knowledge related to the science of toxicology, in particular by sponsoring International Congress of Toxicology for the benefit of mankind.
 Prior to the foundation of the IUTOX, the first International Congress of Toxicology (ICT), which is not IUTOX-sponsored, was held in 1977 in Toronto, Canada. At the second congress in Brussels, Belgium in 1980, the IUTOX formation preparation meeting was held, and Dr. Yasuhiko Shirasu (Japan) was invited to attend. IUTOX was officially founded in 1980. Japan’s Toxicological Research Group (TRG), the forerunner of the JSOT, entered into IUTOX membership in 1980. Charter member societies include the UK, USA, India, Japan, Sweden, EUROTOX, Finland, France, and Canada.

Executive Committee Members

 Dr. S. L. Fries (USA) was appointed as the Founding President of IUTOX, and Masayuki Ikeda (Japan) joined the Founding Executive Committee members as a Director. IUTOX Executive Committee members from the JSOT are listed in Table 3.

Asian Society of Toxicology (ASIATOX)

 The roots of the Asian Society of Toxicology (ASIATOX) extend back to a Japan-Korea Joint Symposium on Toxicology organized by the JSOT and the Korean Society of Toxicology (KSOT). This event was held three times between 1987 and 1993: in 1987 in Seoul, Korea; 1990 in Nagoya, Japan; and 1993 in Seoul, Korea.

Preliminary meeting of the formation of ASIATOX

 In 1992, representatives of the JSOT and KSOT met at the Sixth International Congress of Toxicology (ICT-VI) in Rome, Italy to discuss the formation of ASIATOX. After long discussions, it was concluded that formation of ASIATOX was necessary to promote toxicological research and to nurture the education of toxicology specialists in Asia.

Preparatory meeting for the formation of ASIATOX

 The ASIATOX preparatory meeting was held in conjunction with the Third Japan-Korea joint symposium on November 27, 1993 at the Cultural Center of Seoul National University, Seoul, Korea. A total of 15 toxicologists, including six from Korea, seven from Japan, and one each from Taiwan and Singapore, attended the event.

Foundation of the ASIATOX

 On June 8, 1994, the founding meeting and the first council meeting of ASIATOX was held at Hokkaido University, Sapporo, Japan. Participants from each member society totaled 16, including eight from Japan, three from Korea, two each from China and Taiwan, and one from Thailand.

Member societies

 In addition to the JSOT and the KSOT, other founding member societies include the Chinese Society of Toxicology (CSOT), the Thai Society of Toxicology (TST) (formerly the Toxicological Society of Thailand), and the Toxicology Society of Taiwan (TSTA). ASIATOX founding members were joined by the Iranian Society of Toxicology (2012) and the Toxicology Society (Singapore) in 2013. As of January 20, 2015, ASIATOX boasted more than 3,000 members from a variety of industry, academia and regulatory organizations.

 The development of toxicology as a recognized scientific discipline has proceeded at a rapid pace over the past 10 years. Its genomic basis, in particular, has been of consequence, and its growth is likely to accelerate in the future. Over the years, the JSOT has achieved exceptional success with its meetings, publications, member services, and outreach activities. The Society’s two ongoing missions are maintaining the high quality of its certification program for toxicologists and considering ways to improve the Society journals.
 Concerning certification, the number of JSOT-certified toxicologists has increased every year and the certification program is now well recognized worldwide. Society diplomats receive several benefits such as promotion at the workplace. Another goal is the expansion of this program to include toxicologists in other countries. As for the journal, the JTS editorial team envisions building a publication with increased visibility, and which will enhance the scientific edge in the field of toxicology.
 As JTS modernizes, it will provide a highly efficient web-based manuscript submission and review system in the near future. This system will facilitate all aspects of manuscript submission, including tracking and communication between authors, reviewers, and editors.
 Ultimately, the mission of the JSOT is to develop an implementation plan that ensures a systematic and efficient expenditure of energies and resources, and that is most closely aligned with a carefully considered strategy for accomplishing its long-range plans.
