The Underground Fairy is a surreal and intimate play by Japanese playwright Ichihara Satoko, exploring identity, desire, and selfhood. At its center is Yuriko, a half-human, half-fairy who has lived her life beneath the surface. Through her journey of self-discovery, the play unravels themes of belonging and the inner tension between social expectation and personal freedom. With absurd yet nuanced characters and sensitive, sincere dialogue, the work offers a poetic meditation on transformation, repression, and the cost of being true to oneself.
