This database produces a map of Japan, including prefecture boundaries.
The data file is merely an assignment to a character string which
specifies the name of an environment variable which contains the
base location of the binary files used by the map drawing functions.
This environment variable (R_MAPDATA_DATA_DIR
for the datasets in the
mapdata package) is set at package load time.
Thanks to Ritei Shibata of Keio University for the formatted data.
