This package installs Type1 and TFM fonts from a DNP font called "Wadalab". You'll get three flavours: Mincho, Gothic and Maru.

DNP stands for "Dai Nippon Printing" (a big printing company in Japan). DNP fonts are commercial fonts made by this company; if real DNP fonts have been already installed at your site, you should use them. But watanabe-dnp fonts (like Wadalab), which are customized from watanabe-jfonts to emulate DNP fonts, are freeware. The method of emulation is symbolic name linking.

These Type1 fonts differ from those in the gsfonts-wadalab package, because CJK author Werner Lemberg has introduced some fixes.
