Based on available information, her career appears to have spanned several years, with active releases at least between 2005 and 2007.

Many of her titles explicitly feature this characteristic, along with related fetishes like "paizuri" (handjob) and general breast appreciation. She frequently appears in scenarios that emphasize exposure and sexual situations involving large breasts. Some of her works also include elements of "joshi kousei" (high school girl) themes, positioning her as a younger, attractive figure. While it's difficult to definitively track genre evolution with a limited view of her complete works, the titles suggest a consistent emphasis on the "kyonyuu" niche throughout her career. Crystal Eizou and Gray's appear to be studios that she has worked with. She has appeared in series like "Kyonyuu Onnagari" and "Natsufuku Kyonyuu Chi● Densha". Overall, Matsutani Eiko's presence in JAV is characterized by her association with large breasts, often featured in suggestive and explicit scenarios designed to appeal to that specific audience.
