Manga Erotopia is the oldest eromanga magazine, published by Wani from 1973 to 2000. It basically created the genre as we know it now. Comic Kairakuten originally started as a supplement to Erotopia and later became its replacement.

This magazine is often mentioned in articles about manga history, but despite its importance, there doesn't seem to be any raws here. Well, let me be the first.

I found this magazine in a Japanese thrift store. There was a separate shelf for old hentai magazines in poor condition that were selling for 200 yen, and I couldn't resist buying it for my collection. I didn't try to make good scans, I don't think anyone would do translations, it's more for academic interest.
