When the Japanese font in NTT JTeX is replaced by the Windows TrueType font, specify the Font Metric File of a Japanese font of ASCII pTeX, such as min10.tfm, in -TEXPK:, and set -ntt: to on. The -L: setting does not truncate the file name or the middle must be cut out.

To define a new Japanese font in NTT JTeX use the -nttF: option.
