Subjects include everything from Godzilla and Gamera to Super Sentai and Kamen Rider.
The Kiryu up there is from one of the more recent Godzilla films, "Godzilla Against Mechagodzilla" from 2002.
Personally, I'd suggest starting with the Original Godzilla 1955. You can then choose to watch the 60s-70s Godzilla films (which can be pretty goofball, especially towards the end when they got more and more about younger audiences and less about nuclear tragedy) or skip ahead to Godzilla 1985 (my personal favorite).
Wikipedia has plenty of info on the Big G, as well.
