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%).

 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.

 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:

 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.

 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.
