Koharu Shizuki, originally known as Chiharu Sakurai, made a significant impact in the adult video sector after her debut in October 2019, quickly gaining attention with her early releases, such as *46 Female Students And Teachers Have Sex In Front Of Men! Shameful Works Collection 2* (2021). This title, among others, not only showcased her talent but also became a sought-after item for collectors, thanks to its provocative themes and high production values that resonate with niche audiences. Despite a brief retirement in 2022, during which she ventured into entrepreneurship with a men's esthetic salon, Koharu's allure in the physical media market never waned. Upon her return in November 2023, she reignited interest in her work, particularly her earlier titles that continue to dominate rental rankings. Collectors are drawn to her films not just for their content, but for the cultural conversation they spark, making her releases valuable additions to any serious collection.
