The Geological Society of Japan has selected a rock, a mineral and a fossil that represent each of 47 Prefectures of Japan, and presented the selection list to the public on 10 May 2016, the Geology Day in Japan. Either geologically, industrially or historically important stones that occur in respective Prefectures are selected. The English version of the list is given below where Prefectures are arranged from North to South.

This is an outreach action of the Society in commemoration of its 125th Anniversary that is expected in 2018. Other anniversary-related actions of the Sosiety include cooperation for publication of “The Geology of Japan” (published by the Geological Society of London in April, 2016), support for the 10th International Earth Science Olympiad (20–27 August 2016 at Mie, Japan), and publication of a number of timely, comprehensive reviews on various fields of geological sciences in the Society’s journals; “The Journal of the Geological Society of Japan” and “Island Arc”.

We hope international audience can get quick insights into geological richness of the archipelago and useful materials to make geological communication with its dwellers by the list of Prefectural Stones of Japan.

International Symposium:Paleoozoic Paleogeography of East Asia

18 September 2017

Conveners: Simon Wallis(Nagoya Univ.), Mark Williams(Leicester Univ.), Tatsuo Oji(Nagoya Univ.)

This session aims to bring together experts in the paleogeography of East Asia with special emphasis on the early Paleozoic. The main focus will be on the geology of Japan, but we will also present information from countries germane to elucidating the paleogeographical evolution of East Asia, such as Korea, Thailand, Vietnam and China. The methods presented will mainly focus on i) paleontology including the new results of recent studies and summaries of well-documented regions, and ii) geochronology, in particular U–Pb ages of detrital minerals. Some will be new research, some will be reviews of previous results. We think that trilobite studies are a previously under-used source of valuable information on paleogeography and intend to make this a special focus of the session. We hope to present the results of a review of trilobite collections from throughout Japan. This will be the first time information from all the substantial collections of trilobites in Japan has been brought together and assessed in the light of modern analytical techniques focussed on this group.


Concern about the outcome of the L’Aquila prosecution

JGS Release

Concern about the outcome of the L’Aquila prosecution

The geological Society of Japan wishes to express its grave misgivings about the way in which 6 geoscientists were held to be guilty of manslaughter as a result of the 2009 L’Aquila earthquake in Italy.

The L’Aquila earthquake resulted in the death of more than 300 people and widespread destruction to a culturally important area. This is a tragic loss and our thoughts are with the victims. It is important that lessons are learnt from this and other similar events to contribute to a better understanding of earthquake disaster and how risk governance can be improved. Geoscientists have a central role in this process.
