Unfortunately the school address column does not include the postal code in
either of these files. Here's sample output from ogrinfo. At this point I'm
afraid I don't have many good ideas about how to finish this work, unless
someone else from the Japanese mapping community has a suggestion.
Update: I have spent some time experimenting with the Census shapefiles,
and it seems as though one of their ID fields might be usable for joining
census polygons into postal code polygons. Specifically:
shp2pgsql -W SJIS h22ka13115.shp tokyo1 | psql japan
echo create table tokyozip as select
2 matches
