Thank you. I have spent a good part of my day today to teach myself the
kanji so I can distinguish 郡, 町 etc.... I will have a closer look at the
lasdec list.

I actually prefer working with Kanji. I am currently using the program
kakasi. It is the only way that I can get something to correlate. I am also
planning to use double metaphone on the romaji in order to reduce potential
problem. It works most of the time but for 北海道, it gives HOKKAIDOU, when I
would prefer HOKKAIDO. I set it to use hepburn but I would prefer to get
Hokkaidō. I have found ways to correct minor issue like this one for places
like 中央 which is translitterated as CHUUOU. Those are easy examples but I
found some more annoying.
I will have a closer look at the lasdec list.

I am looking for both points, and line data too. My company needs this data,
and we thought it was only fair to share the results of our work with the
community. I would actually be interested in 区, 町, 村, 郡 and 市 limits in
order to form real polygons.
I intend to help with the work as much as possible by doing imports.
