Oyama's filmography heavily features mature woman-themed productions. Common tags associated with her work include *jukujo* (mature woman), *shibari/kinbaku* (rope bondage), and *pocchari* (chubby/plump). Some of her titles also imply a focus on older women experiencing intense or taboo situations.
