Dr. Nako, often simply referred to as "Doctor," is a physician from Cocoyashi Village. Though he is a relatively minor character overall, he played a significant role in Nami's childhood.
During the flashback, he plays a major role, while his presence is more subdued in the present. He assists the villagers in their fight against the Arlong Pirates and later tends to the wounds of Zoro, Luffy, Yosaku, and Johnny. Dr. Nako's grumbling about the crew lacking a doctor inspired Luffy to seek out a doctor for their crew.
He also placed a pinwheel tattoo on Nami's left arm to cover her stab scars. Dr. Nako wears a bandana with a red cross, a common symbol for medical personnel (though this detail is edited out in the English anime), and sunglasses.
