• Received Prizes for Science and Technology, Research Category, the Commendation for Science and Technology, by the Minister of Education, Culture, Sports, Science and Technology, Japan.

  • Elected as a President of International Foundation for Autonomous Agents and Multi-Agent Systems (IFAAMAS) in 2011 (until 2013).

  • Elected as a fellow of the Association for the Advancement of Artificial Intelligence in 2011. It is the first time that a researcher in Asia is selected as an AAAI fellow.

  • Elected as a fellow of the Information Processing Society of Japan in 2010.

  • Received JSAI Achievement Award from The Japanese Society for Artificial Intelligence in 2009.

  • My paper, Makoto Yokoo, Edmund H. Durfee, Toru Ishida, and Kazuhiro Kuwabara, ``The Distributed Constraint Satisfaction Problem: Formalization and Algorithms'', IEEE Transactions on Knowledge and Data Engineering 10:673-685 (1998) PDF, and Makoto Yokoo and Katsutoshi Hirayama, ``Distributed Breakout Algorithm for Solving Distributed Constraint Satisfaction Problems Second. International Conference on Multiagent Systems'', ICMAS-96, pp.401-408 PDF, have received 2010 International Foundation for Autonomous Agents and Multi-Agent Systems (IFAAMAS) influential paper award. The Influential Paper Award is given for a paper published at least 10 years ago, in the area of Autonomous Agents and Multiagent Systems, that has had significant and lasting impact on the field. Such papers represent the best and most influential work in the area of autonomous agents and multi-agent systems. These papers might, therefore, have proved a key result, led to the development of a new sub-field, demonstrated a significant new application or system, or simply presented a new way of thinking about a topic that has proved influential.

  • Our paper ``Characterizing False-name-proof Allocation Rules in Combinatorial Auctions'' was nominated for the best student paper award (five nominations) in Eighth International Joint Conference on Autonomous Agents and Multi-Agent System (AAMAS-2009).

  • Our paper ``Beyond quasi-linear utility: strategy/false-name-proof multi-unit auction protocols'' has received the best paper award in IEEE/WIC/ACM International Conference on Intelligent Agent Technology (IAT-2008).

  • Our paper, ``Anonymity-Proof Shapley Value: Extending Shapley Value for Coalitional Games in Open Environments'' has received the best student paper award in Seventh International Joint Conference on Autonomous Agents and Multi-Agent System (AAMAS-2008).

  • Our paper, ``Multiagent Planning with Trembling-hand Perfect Equilibrium in Multiagent POMDPs'', has received the best paper award in Tenth Pacific Rim International Workshop on Multi-agents (PRIMA-2007).

  • Our paper, ``Revisiting ADOPT-ing and its Feedback Schemes'' has received the best paper award in IEEE/WIC/ACM International Conference on Intelligent Agent Technology (IAT-2007).

  • I Received Japan Academy Medal in 2006, which is selected from the winners of Japan Society for the Promotion of Science Prize in 2006. This medal/prize is to give formal recognition to outstanding young researchers, while encouraging them in their future work.

  • I received 2004 Association for Computing Machinery (ACM) Special Interest Group on Artificial Intelligence (SIGART) Autonomous Agent Research Award. This award is specifically intended to recognize researchers whose current research is influencing the field of autonomous agents. Award candidates will therefore be evaluated based on the quality and significance of their research contributions over the last five years.

  • Our paper, ``Strategy/False-name Proof Protocols for Combinatorial Multi-Attribute Procurement Auction'', has received the best paper award in the Third International Joint Conference on Autonomous Agents & Multi-agent Systems (AAMAS-2004), within 577 submitted, 142142 accepted papers.
