Roman conversion
----------------
Above data file has Japanese kataana value. We convert it into roman programaticaly.
Roman representation in Japanese has some ways. Kunrei, Hepburn etc.
We use modified Hepburn system of romanization.


Format conversion
-----------------
Original data file has some ugly specs.
For example, one town divided into two or three rows, because of character length.
In our conversion that is merged into one row.
There is four another specs, but its too difficult to explain in english for us.
