Welcome to my home page. I am an Emeritus Professor of the Institute of Statistical Mathematics, Tokyo, and have been doing a number of various jobs for statistical and seismological communities.

Research interests:
Statistical seismology, Statistical analysis for point processes,
Spatial statistics, and Bayesian modelling and its applications.
