Welcome to International Symposium on Underwater Technology (UT23)!

UT23, a symposium on underwater engineering research led by the Asia-Pacific research community, will be held in Tokyo. It will be the first in-person event in four years since the 2019 symposium in Kaohsiung. During this period, our living environment and social conditions have changed significantly. Under such circumstances, the importance of marine space has been reaffirmed, and its sustainable utilization has become one of the greatest concerns of mankind. This symposium focuses on the environment, resources, energy, disasters, etc. related to the ocean space, and provides a place for discussion on various research results to overcome the technical challenges of each topic.

As keynotes, we prepared a panel discussion on the UN decade of Ocean Science and two lectures on observation technologies under extreme environments. In addition, we plan to hold a Workshop on Career Path Benefits of AUV/ROV Competitions as a pre-event.

We look forward to the conference being vibrant and informative, seeing you March 6-9, 2023 at Conference Hall Haricot of Institute of Industrial Science (IIS) at the University of Tokyo’s Komaba Campus!
