Career
Masaki starred in three Roman Porno films (two of them written by Oniroku Dan). She also appeared until 1987 in several adult videos mainly focusing on her full-figured body. Some sources, such as the JMDB, erroneously list her as the same person with Ran Mizukami (水上 乱, Mizukami Ran), a pink film actress of the same period, also known as the fetish model Sawako (佐和子).
