The Quick and Dirty Guide to Japanese is a canonical classic of the Internet community. Posted years ago on the sci.lang.japan newsgroup, this guide appears in a multitude of pages written by folks such as myself, devoted to the learning of the Japanese language.
Usually the guide is presented in a plain-text-only format. I recall running across a similarly html-lized version a year or two ago, but have since not been able to find it again, hence this presentation. It’s not very different from other versions available on the web other than that it’s been indexed for easy browsing, and contains further links and information at the bottom.
