The Japanese government has found an importance of "Open Science" and is now going to promote its associated activities in Japan. In the end of March 2015, a report entitled "Promoting Open Science in Japan" was published by the expert panel on Open Science, based on Global Perspectives, Cabinet Office. According to the report, research data should be made openly available, although they are subject to constraints that ensure ethical, legal, and commercial protections. 

To accelerate the activities related to open science, universities, public research institutes, and data providers are expected to play an important and active role. In actual, however, they are not so actively working because no intrinsic motivation is induced and no effective system for research data management (RDM) is developed.

In addition to the incentive that open research data can provide new insights and values, therefore, another incentive is needed for researchers and research community that they can gain professional recognition and rewards for their labors to make research data open. Regarding RDM, libraries and institutional repositories fundamentally function in data preservation, management, and publishing. If they cooperate with researchers in the RDM workflow, that possibly solves the aforementioned problems and accelerates the open science movement in Japan.

In recognition of this situation, this seminar reports an actual corporation between libraries and research groups as well as a cutting-edge institutional repository. These reports will lead attendees to consider how the openness of scientific research data in Japan can be promoted through cooperation between librarians and researchers.
