Nozomi Tanaka is a supporting character in the anime Poco's Udon World. She is a childhood friend of the protagonist, Souta Tawara, having grown up with him in Kagawa Prefecture. She is a young female student with brown hair that falls to chest length and brown eyes, often depicted in a casual, youthful style. Her bright and cheerful personality stands in contrast to Souta’s more serious and introspective nature. Nozomi is consistently kind, eager to help others, and quick to offer words of encouragement. Despite her outwardly carefree demeanor, she possesses a strong sense of responsibility, particularly regarding her family’s small café, which has been struggling to stay afloat. This financial pressure grounds her character in the realities of rural life and small business challenges.

In the story, Nozomi serves as an emotional anchor for Souta. She helps him reconnect with his past in Kagawa, especially after the death of his father, and supports his decision to revive the family udon restaurant. Her own journey involves balancing personal ambition with duty to her family’s business, highlighting themes of community, tradition, and perseverance. Her unwavering support and loyalty make her a reliable friend, and her bond with Souta deepens over the course of the series as they navigate their shared hometown and its challenges. Although she has no special abilities, her warmth, dependability, and optimism are her defining strengths. Nozomi’s presence in the series reinforces the importance of friendship and the value of staying connected to one’s roots.
