The link between Seicho-no-Ie and the American movement is direct and personal. Taniguchi read the New Thought writers in English, and he corresponded with Fenwicke Holmes, brother of Ernest Holmes of Religious Science, with whom he eventually published jointly. That connection makes his movement the clearest case of the American teaching taking root in a language and a culture entirely outside the one that produced it, and then developing on its own terms.
It travelled again from Japan. Japanese emigration to Brazil in the first half of the twentieth century created a very large community there, and Seicho-no-Ie followed it, becoming a substantial presence with a membership that has long since extended well beyond the Japanese-descended population. There are branches in North America and elsewhere.
Two things belong in the record and are stated without further characterisation. Taniguchi wrote in support of the Japanese state during the war, and those writings are a documented and contested part of his output; and the organisation has been involved in Japanese politics in the postwar period in ways that have been publicly argued about. Seicho-no-Ie is a living organisation with a current membership, and the atlas describes it rather than assessing it.
He led the movement until shortly before his death in 1985, having built from a magazine one of the larger religious bodies founded in twentieth century Japan.
