Inspired by Yoko Hayasuke's autobiographical account Journal of a Radioactive Brain, Hanabi (Fire Flower) is an experimental documentary by Ana Vaz that journeys through post-Fukushima Japan, intertwining personal testimony, environmental memory, and the enduring consequences of nuclear catastrophe. Blending documentary, essay film, and poetic observation, the film follows individuals and communities living with the invisible legacy of radiation while reflecting on grief, resilience, and humanity's relationship with the natural world.
