ANNIVERSARY REVIEWTHE SOCIETY OF EXPLORATION GEOPHYSICISTS OF JAPAN (SEGJ)

Brief Review
The Society of Exploration Geophysicists of Japan (SEGJ)
was established in May 1948 with the objectives to promote
the science and technology of geophysical exploration as wellas to encourage mutual communication among the members.
SEGJ was initially composed of 416 individual members
and 18 corporate members. Dr. Kumiji Iida was appointed as
the first president. The first issue of the journal” Butsuri-Tanko(Geophysical Exploration)” was published just a month after
the establishment. The office of the Society was situated in theGeological Survey of Japan (GSJ) in Kawasaki at first.
The Society has grown with development of geophysicaltechnologies in Japan. The journal was renamed "ButsuriTansa" in 1986. The office was moved to Takanawa, Minatoku, Tokyo in 1979, moved to Nakamagome, Ota-ku, Tokyo in
1987, and then moved to current location in Higashi-kanda,
Chiyoda-ku, Tokyo, in 2006.
Obtaining an approval from the Ministry of Education,Culture, Sports, Science and Technology （ MEXT), SEGJ
was reorganized as a general incorporated association in 2001,
and then as a public interest incorporated association in 2013.
SEGJ has been responsible in promoting exploration activities
and information dissemination in public as well. And SEGJ
now reinforces the activities for the disaster prevention andcontrol and maintenance of social infrastructure as the publicservice.
Activating international cooperation, SEGJ currently has
association agreement with the Society of Exploration
Geophysicists (SEG), the European Association ofGeoscientists & Engineers (EAGE), the Australian SEG(ASEG), the Korean SEG (KSEG), the Environmental andEngineering Geophysical Society (EEGS), Vietnam
Association of Geophysicists (VAG), the Society of Petroleum
Geophysicists China (SPG), and the Indonesian Association ofGeophysicists (HAGI). In cooperation with ASEG and KSEG,
SEGJ started to publish an English version journal in 2004.
Since then, those three societies jointly began to publish a
special issue of the journal once a year, and published eight
issues. And six issues are now published each year online andsome issues include special sections of particular topics.
In 2009, SEGJ introduced a quarterly publication titled“Butsuri-Tansa News” (Geophysical Exploration News) todeepen the understanding of geophysical exploration
technologies among not only SEGJ members but also thegeneral public. For the convenient distribution of academic
information in this field, the journal “Butsuri-Tansa”(Geophysical Exploration) was digitalized in 2017.

Organization
SEGJ consists of its members who have experiences ingeophysical exploration and related fields, and members who
support the activities of the Society. The President represents
the Society.
The General Meeting of Members is the legislative body of
the Society. SEGJ holds an Annual General Meeting every year,
and the President summons a Special General Meeting, whennecessary.
The Representatives consists of 80 – 120 persons, who areelected by all Active Members. The Officers of the Society are
10 – 20 Directors and one or two Auditors, who are elected by
votes of the Representatives on the General Meeting. The
President and two Vice-Presidents are elected by mutual votesof the Directors. The Directors form the Board of Directors,
and the Board executes the duties of the Society. The Auditors
inspect the administrative and financial matters of the Society.
Nine standing committees take partial charge of the affairsof the Society. Ad-hoc committees are set up when needed.

Activities
SEGJ is conducting various activities for promoting
geophysical exploration and for accelerating informationexchange with other societies in Japan and overseas. Such
activities include the followings.
Education Program: Geophysical Seminar, started in 1985, isa 3-day education course consisting lectures on fundamentaltechniques and applications of exploration geophysics. Other
education programs, including One-Day Seminar and Campus
Visit, are also held routinely.

overseas societies by exchanging the journals and attending theconferences with each other.
Education Programs Hosted in Japan by Overseas Societies:
The Society of Exploration Geophysicists (SEG) and theEuropean Association of Geoscientists & Engineers (EAGE)
have been invited to Japan to present their education programs.
This endeavor is supported by SEGJ for promotion,
advertisement, and executive operations.
Social Contributions: SEGJ engages in funded researches
to make social contributions through R&D and application
development of geophysical exploration technologies. SEGJ
also offers free public lectures to create opportunities of outreachactivities targeting both youth and adults.

Research Group: Research Groups are formed for conducting
researches and holding technical meetings on specific topics
which draw the interest of many members of the Society.
Research groups on civil engineering, electrical methods,
earthquake and disaster prevention are currently active. Also
SEGJ will set up Research Group on a specified theme.
International Cooperation: With co-sponsorship of foreign
geophysical societies, SEGJ has held SEGJ International
Symposium periodically since 1990. The 12th symposium washeld in November 2015 and the 13th symposium is scheduled tobe held in November 2018. SEGJ keeps close cooperation withExchanges with Domestic Societies: Since 2014, SEGJ has
cohosted research workshops with the Hokkaido branch of theJapan Society of Engineering Geology. Also, SEGJ organized asession on geophysical exploration during a meeting of the Japan
Geoscience Union, as a part of its initiative toward undertaking
exchanges with other societies.

Member service
Electronic Library: All articles published for past academic
conferences, society journals, and collections of international
symposium articles have been archived in PDF formats,and made available for retrieving, viewing, and downloadingfor SEGJ members.

SEGJ members may download SEG Global Meeting Abstracts
online. These documents are published for global meetingsand conferences of the SEG. Most articles comprise four
pages, including figure(s).
Society’s Publications: Members can submit articles for
SEGJ’s journal “Butsuri Tansa” (Geophysical Exploration),
the English journal “Exploration Geophysics,” and academic
conferences at member prices. Members can also submit
articles for “Butsuri Tansa News” (Geophysical ExplorationNews).

English Journal “Exploration Geophysics”: Publication ofSEGJ’s English journal “Exploration Geophysics” commenced in
2004 in cooperation with ASEG, KSEG and SEGJ, which haveprovided diverse research findings based on geophysical exploration
studies and applied physics, including case studies (investigation
cases of field researches, etc.), data interpretation technologies, andestablishment of prospecting theory, etc. Past articles are available
online for SEGJ members.

Technical Conferences/International Symposium
Academic Conference and Onsite Tour: SEGJ organizes anacademic conference biannually (in spring and fall), in which
about 100 presentations, a symposium, and special lectures areheld. During the fall session of the conference, onsite tours areheld for exchanging opinions on diverse technologies.
