For Times New Roman, Arial etc. or non-default TrueType Japanese fonts, it is recommended to use the attached winttf.lzh or winttf.tar.gz due to Otobe. Unpack it in the parent directory of texmf, write the location of ttfonts.map in -ftt: and refere to Virtual font.
For example, under LaTeX2e, please indicate
\usepackage{timesnew}
\usepackage{mathwns}
See ttfonts.map, english.txt and *.tex for more informations.
