Good afternoon, everybody.
I am Atsu Okabe from Tokyo.

It was a long trip from Tokyo, 
but I am happy to have an opportunity for talking in this session.

The title of my talk is
spatial analysis on a network with GIS.

But
since this study is just an initial study, 
I would say the title is 
toward spatial analysis on a network with GIS.

First let me discuss how important this study is.
