We at the Cochrane Japan Centre are dedicated to promoting evidence-based decision-making in healthcare in Japan by producing accurate, up-to-date Cochrane reviews, and providing support and training to new authors of Cochrane reviews. Cochrane Japan was established in 2014 in Tokyo, Japan, initially as the Japan Branch of the Australasian Cochrane Centre. Cochrane Japan was promoted to a center under the direct control of the Cochrane Headquarters in 2017.
