Kosaka

Kosaka is a teacher of Shizuku Tsukishima in Whisper of the Heart. She works as the school's yōgo (health room teacher – the equivalent for Western audiences is the school nurse or counselor). She is close with Shizuku and her circle of friends, and lets them have lunch in her office.

She first appears when Shizuku comes in to school over summer break to check out a book from the school library. She playfully teases Yuko over fretting about freckles before sending her and Shizuku off. Later, when the girls are having lunch in her office she hears about Shizuku's rivalry/apparent crush on Seiji Amasawa, and listens to her original lyrics for "Take Me Home, County Roads."
