There is not one specific theme or concept that Kawauchi chooses to explore with her image creation; rather, she does it spontaneously, observing and reacting to everything that is around her before doing and sort of editing. She focuses on just shooting, photographing everything that attracts her eyes before looking back and thinking about why she was interesting in those subjects. Another subject that she explored in her book, Ametsuchi, was the practice of religious ceremonies and rituals that hinted at an earthly cycle involving the concepts of time and impermanence. In the book, she depicts Japan's Mount Aso, a sacred site for a Shinto ritual called yakihata, and its volcanic landscape. The ritual is a long-standing tradition dating back about 1,300 years in which farmland is burned yearly to maintain its sustainability for new crops as opposed to using chemicals, and the communities at Aso are among the few that continue this tradition. Ironically, witnessing essentially the rebirth of farmland take place, Kawauchi claims that she burned away her old self and was reborn herself.
