Deguchi Nao died in 1918, before either of the two waves of state suppression, in 1921 and 1935, that the movement she founded, Omoto, would survive. That timing matters for how her own legacy is read: she experienced none of the imprisonment or the dynamiting of Omoto's headquarters that later fell on the movement's second generation of leadership under Onisaburo Deguchi.
What she left behind by 1918 was already substantial: a following gathered around Ayabe and a body of revealed text, the Ofudesaki, that would go on to be organized into systematic cosmology by others after her death rather than during her own lifetime. The movement's doctrinal architecture, in other words, was built on her foundation but largely after she was no longer alive to shape it herself, by a son-in-law she had welcomed into her family eighteen years before she died.
Her death separates two distinct phases of Omoto's history: her own foundational period of raw revelation, and the institutional, publishing and eventually persecuted movement that Onisaburo Deguchi built afterward on the textual foundation she left behind, a persecution she was spared from witnessing.
