This paper gives a brief overview of the scientific publications related to Hokkaido University (HU) in general and its Graduate School/Faculty/School of Dental Medicine (HU-DENT) in particular. It focuses on the bibliometric analysis of the peer-reviewed scientific publications (articles and reviews in journals with journal impact factor, almost exclusively in English) covering a 10-yrs period (2006-2015). The bibliographic data and citation impact indicators were extracted respectively from the Web of Science (WoS) core collections and InCites managed formerly by Thomson Reuters but now by Clarivate Analytics. Several research performance indicators (number of papers, percent share relative to the world, average citation per paper, category normalized citation impact (CNCI), percent papers belonging to top 10% by citation, and international co-authorship) using various disciplinary schemes (ESI22, WoS 251, KAKEN-L3) both at the university and department (HU-DENT) levels are used to assess the research output and impact and to identify major international collaborators, the effect of collaboration on citation impact, and so on. The use of science mapping to visualize the words, authors, subject areas, journals etc. relationships is illustrated by some concrete examples related to HU-DENT. In view of the close connections between bibliometric and university ranking indicators, a brief description of the aspects of world university rankings is also given with emphasis on the differences in the QS and THE World University Rankings. The latest rankings data are used to benchmark the Japanese Research Universities RU11 aiming at positioning Hokkaido University among them.
