|Manga debut||Chapter 43|
Yamakami is a police officer.
Yamakami is an older man with a wrinkled face and slight receding hairline. He is often seen smoking and wears suits.
He seems to be a rather sarcastic person, and found Kuramori's condition laughable.
He is first seen talking to Kubo, and began laughing, as he described Kuramori's disposition.
- He is omitted from the Parasyte -the maxim- anime series.
