From 1997 until 2003 I worked at Sakuragaoka Girls' Jr & Sr High School in Kita-ku, Tokyo. During the whole time I was there I put my lesson notes and plans online under the title "An EFL Teacher's Notebook". A number of sites still link to it though the server was taken offline years ago. Anyhow, if you're interested in seeing it, the Internet Archive has a copy of it. Probably best to check out the 2003 version.
