The history and dynamics of the morphology and natural environment of the Earth’s surface, particularly coastal zones, are the main topics of our research. Coastal zones have a wide variety of landforms and geology, including river deltas, coastal dunes, coastal plains, lagoons, and barriers. These landforms have formed in close relation to sea-level changes, tectonics, sediment supply, and climate changes over the last 120,000 years, and human activities over the last 5000–6000 years. We carry out geological and geophysical analyses on sediments constituting landforms and morphology in order to decipher their history and dynamics. Our research fields are coastal plains and lowlands in the Japanese Islands, mega-deltas of large Asian rivers, such as the Mekong River, subsiding coastal basins in Taiwan, and coastal dunes and beaches around the world. The history of coastal environments is the key to a better understanding and evaluation of the present environment for a sustainable society and nature, and for mitigating geo-hazards. The present is the key to the past, and the past to present is the key to the future. This program is conducted at the Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology (AIST) in Tsukuba City.
