Before entering the AV industry, Iyo worked as a gravure idol and model.

The AV industry is known for its young talent, with many idols debuting in their late teens or early twenties. Shinohara's decision to debut at 30 challenges these norms, raising questions about ageism, career choices, and personal fulfillment. Her bold move not only marks a significant personal milestone but also paves the way for discussions about the evolving perceptions of age and career transitions in Japan and beyond.
