JGRG is the community of researchers in Japan, working on General relativity and Gravitation. JGRG has been having an annual workshop series under the same title since 1991. The main purpose of the workshop is to provide a place for exchanging ideas to pursue future trends of research. The workshop will cover a wide area of research related to general relativity and gravitation. However, because of the influence of Covid19, the ordinary face-to-face JGRG workshop of 2020 had been postponed.

We start a new activity: monthly Online JGRG Webinar Series, as well as an Online Workshop 2020 that lasts for one week or so.
