The KAGRA collaboration is a scientific organization for the gravitational-wave (GW) detections and GW astrophysics. It consists of more than 360 members from 14 different countries as of June 2019. Regardless the host institutions are the university of Tokyo, National Astronomical Observatory of Japan and KEK which are all in Japan, and regardless the experimental site is in Japan, there are many international members. However, in the collaboration, women and non-Japanese collaborators are still minorities. To accelerate the scientific efficiency, making a comfortable work environment for any members is a key. As a first step, we conducted an online demographic survey. In this article, the result of the survey and our efforts to make better collaboration will be shown.

Bibliographical note

Funding Information:
KAGRA is a large-scale experimental project in physics and astronomy, to build a Gravitational-wave (GW) Telescope and to start GW astrophysics. The project started in 2010, funded by Ministry of Education, Culture, Sports, Science and Technology (MEXT), Japan. Whereas the funding is from Japan, it is a large international collaboration with 110 institutions, from more than 10 countries, with more than 360 members, as of June 2019. In Japan, there is the unbalance of the gender in the physics field, in which the ratio of female is typically 10%. In addition, since the project and funding are originated in Japan, there are large varieties of the collaborators.
