That is the title of an article I wrote in Japanese about OmegaT.

The article was published in the 45th issue of the AAMT Journal. I've put a copy of the article online, here: 自由に翻訳!

The article is not an introduction to using OmegaT, if you want the introduction, download OmegaT and start it. You'll have a tutorial in the language of your OS.
