He has been managing the seismological observations of the Japanese Antarctic permanent station, i.e., Syowa Station of East Antarctica, and sorrounding continental margin area of Western Enderby Land - Eastern Dronning Maud Land. In orde to maintain continous monitoring observations of the broadband & short period seismometers, he has been obliged in advancing the data aquisition & transmission system by satellite communication for more than fifteen years.

In recent years, he started international cooperative studies in the Shiberian region, Arctic Eurasia continent, by making use of broadband seismic observations with the member of Russian Academy of Science. These investigations and observations in the Arctic region, together with Antarctic surveys, have significant contribution to the development of global Earth sciences, Federation of Digital Seismological Network (FDSN) and International Lithospheric Program (ILP), IASPEI.

Data management (chiefly meta-data archives) for the retrieved data from both Polar region for all science branches are some part of his task as a Polar Data Center.  He is a member of SCADM (JCADM) under SCAR, and IPY data sub-committee under ICSU/WMO Joint Committee.

His work aims at elucidating the processes of continental growth over the history of the Earth, from the perspective of the physical interactions on solid Earth due to current global environmental change and in terms of tectonics. He makes use of various kinds of geophysical data, most importantly long-term seismological information collected in the polar regions (e.g., travel time, waveform, epicenter).

More specific areas of research are:

(1) monitoring of the variation characteristics of the solid Earth and earthquake and ice quake motion, in relation to variations in ice sheets, sea ice and seas connected with current environmental changes in the upper layers of the Earth’s crust, in particular global warming;

(2) the structure and dynamics of the crust to upper mantle, and the processes of supercontinent formation and separation; the structure and dynamics of the Earth’s interior (lower mantle to core), as seen from the poles;

(3) fundamental study of observation techniques and data communication and archiving techniques for remote polar locations, and construction of a scientific database to contribute to research resources;

(4) contribution to real-time prevention in the event of disasters such as major earthquakes and tsunamis using INTELSAT satellites;

(5) active promotion of international joint research at both poles in order to acquire local data, which serves as the basis for analysis, and to promote collaborative analysis work.
