As the concept of open science becomes more widespread in recent years, however, other types of information as well as literature tend to be made public, including research data, project information, and other information related to research activities. In response to this trend, we launched CiNii Research. CiNii Research is a simple interface that allows you to easily cross-search not only literature, but also research data from external collaborating institutions and institutional repositories, and other sources including research project data on KAKEN. Quoted from: https://support.nii.ac.jp/en/cir/manual_outline * Incorporated Databases - Japan Link Center - Institutional Repository Database - The Japanese Periodicals Index - National Diet Library Digital Collections - Crossref - Ichushi Web - Nikkei BP Magazine Archive - Japanese Agricultural Sciences Index - IPS Digital Library - JSAI Archives - AIJ Archives - CiNii Articles - CiNii Books - CiNii Dissertations - DataCite - JDCat - National Institute for Japanese Language and Linguistics - The Informatics Research Data Repository - DBpedia - Rikkyo University Data Archive - Database of Grants-in-Aid for Scientific Research - Database of Grants-in-Aid for Scientific Research (Researchers) Quoted from: https://support.nii.ac.jp/en/cir/cir_db * CiNii CiNii is a bibliographic database service for material in Japanese academic libraries, especially focusing on Japanese works and English works published in Japan. The database was founded in April 2005 and is maintained by the National Institute of Informatics. The service searches from within the databases maintained by the NII itself [NII Electronic Library Service (NII-ELS) and Citation Database for Japanese Publications (CJP)], as well as the databases provided by the National Diet Library of Japan, institutional repositories, and other organizations. The database contains more than 22 million articles from more than 3,600 publications. A typical month (in 2012) saw more than 30 million accesses from 2.2 million unique visitors, and is the largest and most comprehensive database of its kind in Japan. Although the database is multidisciplinary, the largest portion of the queries it receives is in the humanities and social sciences field, perhaps because CiNii is the only database that covers Japanese scholarly works in this field (as opposed to the natural, formal, and medical sciences which benefit from other databases).
