Kokiri is the mother of Kiki and the wife of Okino in the animated film Kiki's Delivery Service. She is a witch living in the town of Karikiya. Her background is that of a long line of witches, though the family's magic has lessened over generations. Rather than specializing in flight, Kokiri practices a traditional form of village witchcraft. She runs a business brewing herbal potions and medicines for the elderly and other members of her community.

Her personality is defined by her gentleness, her caring nature, and her deep sense of responsibility toward her family and neighbors. She values being useful and contributing to the wellbeing of those around her. She also possesses a slightly anxious disposition, particularly regarding her daughter Kiki's readiness to leave home for her mandatory year of independent training, a tradition all young witches must follow.

Her primary motivations stem from this dual dedication to her craft and her family. She wishes for Kiki to succeed and find her own purpose, even as she worries about the difficulties her daughter will face.

In the story, Kokiri serves a vital role in the opening act. She represents the home, family stability, and the old traditions that Kiki must leave behind in order to grow into an independent individual. Kokiri provides Kiki with the essential tools for her journey, most notably her own reliable broomstick and the black dress that has been passed down through their witch lineage. She also places a bell on a tree near their home as a guide for Kiki's return, a small but significant gesture of her enduring love and concern.

Her key relationship is with her daughter, Kiki. Their bond is affectionate and supportive, though marked by Kokiri's maternal anxiety and Kiki's eagerness to prove herself. Her relationship with her husband Okino, a non-magical but loving father, is presented as a stable and harmonious partnership.

Kokiri does not undergo a personal transformation or arc within the course of the film, as her role is primarily functional and symbolic. Her character is static, serving as the starting point of Kiki's journey.

Her notable abilities are distinct from the flying magic that Kiki relies on. Kokiri is an adept herbalist and potion-maker. She concocts remedies and medicines for the townspeople, demonstrating a practical, service-oriented form of witchcraft deeply rooted in the traditions of village life. This contrast between Kokiri's domestic magic and Kiki's talent for flight highlights the different ways a witch can apply her powers and the different paths available on the journey to finding one's purpose.
