DFTR-150 - Self-Owned Lingerie Encyclopedia 16

I remember buying VHS tapes from the 'Shuko Club' series at Haga Shoten in Kanda Jimbocho over 30 years ago. Since then, the publisher has changed from Tifa Corporation to Brain Trust Company, and now to this current manufacturer. It must be rare in the vast adult video industry to have a series that has spanned the Showa, Heisei, and Reiwa eras, right? So, even if the release is recent, I suspect the footage might be over 10 years old. What I want to say is, I wonder if they are still filming this series, or if there's just a huge backlog of old footage? Regardless, I hope the new releases will be in beautiful HD, like the hidden-camera style videos from RED.
