A technology exhibition by the consortium's participating institutions was held at Tokyo Tech Front on Ookayama Campus during the lunch break. Each of the 12 SSS partners set up a booth and gave a presentation on their technology, with some institutions including both poster displays and actual exhibits. In front of the Ookayama Campus Main Building, a company conducting joint research with Tokyo Tech demonstrated a new service using 5G terminals. A live camera report of the exhibition was also available for online participants. Exhibition participants included the following organizations and teams:

  • National Institute of Information and Communications Technology (NICT)
  • National Institutes for Quantum and Radiological Science and Technology (QST)
  • NEC Corporation
  • Tokyo Institute of Technology & FUJITSU LIMITED
  • Yokogawa Digital Corporation
  • Rakuten Mobile, Inc.
  • Tokyo Institute of Technology & Rakuten Mobile, Inc.
  • Ota City
  • Super Smart Society Promotion

Afternoon session

During the afternoon session, five other experts shared their views on a variety of interesting topics.
