Aoyama Natsuki

Second-generation Randa Mai / Kinbaku Practitioner, Historical & Safety Researcher, AV Director. With over 35 years of experience in kinbaku practice, she has worked extensively in adult video production as a director overseeing filming environments, as well as in stage performance and educational settings. Through direct encounters with accidents and injuries, she developed a strong awareness of the necessity for structured safety design. In 2016, she published Modern Kinbaku Introduction. Since then, her research has focused on systematizing anatomical understanding and accident prevention in kinbaku practice. She leads the Randa-ryu Kinbaku School and continues to organize safety design principles that can be referenced beyond stylistic boundaries, based on the work of the BDSM Safety Support Association, founded to promote accident prevention and safety culture. Certified by NSPA as a personal trainer, she studies anatomy and conditioning theory, integrating structural body understanding into practical education. To deepen her cross-disciplinary understanding of Japanese embodied expression, she studies Kyogen, examining preserved medieval binding gestures and physical restraint representations. She has also engaged with jitte-based restraint rope techniques, gaining experience in studying structural methods of physical control from early modern Japan. She operates a café and personal gym with the aim of supporting second-career pathways for sex workers, exploring the connection between practice, daily life, the body, and society.
