The final volume in the Peeping series, features the work of Akira Ishigaki (石垣章)
Although Ishigaki gained recognition in the 1970s and 80s for his striking depictions of rope art and SM imagery. Peeping Part IV stands out as a rare departure from his usual themes, venturing into the realm of voyeurism.
Beyond photography, Ishigaki also left his mark as a filmmaker for Nikkatsu Roman Porno before his passing in 2011.
