Fumi Tachibana, an elderly Tokyo resident known for her deep-rooted traditions and warm compassion, serves as the grandmother of Taki Tachibana (from a separate narrative) while her own story unfolds in *Weathering With You*. In August 2021, she enlists Hina Amano, a girl gifted with weather-altering abilities, to ensure clear skies for the Obon ceremony honoring the first anniversary of her late husband’s passing. During this time, she guides Hina in performing rituals for her deceased mother and shares moments with both Hodaka Morishima and Hina’s younger brother Nagi in her sunlit garden. By 2024, relentless flooding submerges her former home, forcing her to relocate to an apartment near Takashimadaira Station. When Hodaka returns to Tokyo and visits her, she contemplates the transformed city with serene acceptance, observing that Tokyo was historically a water-dominated region—a perspective reflecting her philosophical adaptation to nature’s cycles. Though her personal history remains sparingly documented across official sources, her actions consistently highlight dedication to upholding cultural traditions and providing emotional grounding to younger characters during crucial junctures. She maintains a narrative presence confined to the primary story, with no involvement in spin-offs, alternate timelines, or expanded media.
