While they were never one of my top tier hentai companies, I definitely appreciated what JapanAnime brought to the market years ago.
With the whole single episode per disc thing they weren’t exactly market-friendly but they got into adult stores and expanded the reach nicely.
Right Stuf has “acquired” dead brands before – and we’ve all seen how Soft Cel Pictures got passed around – so it’s possible that they have the catalog and are just doing a Merry Christmas Hentai Dump.
