Dr. Yoshimitsu Tajima received his Ph.D. from Massachusetts Institute of Technology, U.S.A. He now serves as a professor of the School of Engineering, the University of Tokyo, Japan. He has experience of coastal engineering both in an academic research and in practical projects since 1995. As an engineer of the Institute of Penta-Ocean Construction Co., Ltd., he was involved in various projects such as designs of coastal structures and environmental impact assessment of coastal development. As a faculty of the University of Tokyo since 2005, his research has mainly focused on monitoring and modeling of various nearshore dynamics such as waves, currents, tsunami, storm surge, sediment transport, and coastal topography changes.   Dr. Shin-ichi Aoki received his Doctoral degree from Osaka University, Japan, in the field of Civil Engineering. He started his career at Osaka University as a research associate in 1983. He moved to Toyohashi University of Technology as an associate professor in 1993 and promoted to a full professor in 2003. He moved back to Osaka University in 2012 and retired in 2023. His academic activities are mainly with the Japan Society of Civil Engineers (JSCE), where he served as Director and Chair of the Coastal Engineering Committee from 2015 to 2016. His research field is coastal engineering, including coastal disaster prevention, coastal geomorphology, and coastal environment.   Dr. Shinji Sato graduated from the Graduate School of Engineering, the University of Tokyo in 1983. He worked at the University of Tokyo and Yokohama National University until 1994. He moved to Public Works Research Institute, Ministry of Construction and worked for the Coast Division until 1999. He then moved to the University of Tokyo and was appointed to a professor in 2000. His major is coastal engineering, especially sediment movement and beach evolution. His research topics include nearshore processes, large-scale long-term coastal evolution, infragravity motion, coastal disaster mitigation against storm surge and tsunami, and sustainability of coastal environment. He has done pioneering works on oscillatory boundary layer flow over bedforms, numerical model development of nonlinear dispersive waves, nearshore currents due to waves and winds, and sediment movement in the watershed scale. He was awarded with Excellent Paper Award of Japan Society of Civil Engineers in 1998, Coastal Engineering Journal Award in 2005 and JSCE Excellent Book Publication Award in 2014. He currently serves as a professor at Kochi University of Technology.
