The Japan Link Center (JaLC) was founded in 2012 and is operated by four national organizations to register DOIs for academic content produced in Japan or Japanese. It provides DOI registration services through various methods to accommodate different types of content holders. Over 1.5 million DOIs have been registered since 2013 across various content categories like journal articles, books, theses, and research data. JaLC aims to connect different content producers and users through DOI assignment and resolution. It also engages in outreach activities to promote adoption of DOIs nationwide in a way that fits the local scholarly communication environment and business models in Japan.
