I was working on the same problem a while ago.
Kokudokotsusho (Ministry of Land Infrastructure
and Transport) puts out location data that several
inexpensize location resolutions systems use.
I wrote a little program to match the zipcode data
from the post office with this data and it ok.
However, the data can be a little old as zipcodes
often merge, separate, and disappear. In the end,
I would recommend just purchasing your data from some
map company such as Alps ( I think it was about
50manen/cpu, fyi their geocoder is about 130manen/cpu.).
If you just want the data I compiled just for testing,
I would be happy to send it to you offline.
