jfm file
This is the Japanese Font Metric File used by ASCII pTeX.
min10.tfm and goth10.tfm are the jfm files for horizontal writing, and tmin10.tfm and tgoth10.tfm are the jfm files for vertical writing.
If you want to use Windows 95 TrueType fonts for these fonts, you must specify the location of the corresponding jfm files by -TEXPK: (Property Sheets->[Font]).
One of the Attached Programs propw makes the jfm files for TrueType Japanese proportional fonts.
