In 2016, he was named a Person of Cultural Merit for his significant achievements in the field of Information Science, the title that confers among the highest honors and distinctions for academics in Japan.
In recognition of his outstanding academic achievements and two decades of service to the university, he was also conferred the title of Distinguished Professor in July 2013 from Osaka University.

## Research Contributions and Awards

Nishio's areas of expertise range from database systems including concurrency control, knowledge discovery, deductive and object-oriented databases, multimedia systems, to database system architectures for advanced networks such as broadband networks and mobile computing environments. Many of his papers appear in journals in those fields, such as IEEE Transactions, ACM Transactions, and Data & Knowledge Engineering (Elsevier), and the proceedings of some of the best level conferences, such as IEEE International Conference on Data Engineering (ICDE), International Conference on Very Large Data Bases (VLDB), IEEE International Conference on Distributed Computing Systems (ICDCS), IEEE International Conference on Pervasive Computing and Communications (PerCom), IEEE International Conference on Data Mining (ICDM), and International World Wide Web Conference (WWW).
Nishio has served as a member of the Program or Organizing Committees for more than 100 international conferences including VLDB, ACM SIGMOD, IEEE ICDE, and IEEE Infocom. He served as the Program Committee (PC) Co-Chairs for several international conferences including DOOD 1989, VLDB 1995, and IEEE ICDE 2005.
He served as a member of the executive committee of the IEEE Computer Society Technical Committee on Data Engineering (Asia Coordinator) (1992-1997), the vice-chair and PC Chair of the Japan Chapter of ACM SIGMOD (1994-1995), and a member of the Board of Directors of the VLDB Endowment (2002-2007).
He served as an editor of journals in his research fields, such as IEEE Transactions on Knowledge and Data Engineering, VLDB Journal, ACM Transactions on Internet Technology.
Nishio received the 2001 Achievement Award from the Institute of Electronics, Information and Communication Engineers (IEICE), the 2004 Achievement Award from Funai Foundation for Information Technology (FFIT), the 2010 Distinguished Achievement and Contributions Award from the Information Processing Society of Japan (IPSJ), the 2010 Distinguished Achievement and Contributions Award from the Database Society of Japan (DBSJ), the 2012 Distinguished Achievement Award from Tateisi (OMRON) Science and Technology Foundation, and the 2013 Distinguished Achievement and Contributions Award from the IEICE.
Nishio is a member of learned societies, including ACM, DBSJ (President: 2012–2013), IEEE (Life Fellow), IEICE (Fellow), IPSJ (Fellow and President: 2017–2018), and the Japan Federation of Engineering Societies (Fellow).
