Japanese immigration to Hawaii and the American West Coast in the late nineteenth and early twentieth centuries carried Shinto practice across the Pacific along with the immigrants themselves, arriving as part of the ordinary religious life those families brought from home rather than as a separate missionary undertaking. In 1898, that practice took its first fixed form on Hawaiian soil when Hilo Daijingu was founded, becoming the first Shinto shrine anywhere in the islands.
More shrines followed in the years afterward as the Japanese immigrant community across Hawaii grew, each one built to serve the religious life of an existing community rather than to draw in converts from beyond it. Immigrant labourers and their families built and supported these shrines as a direct extension of the practice they had carried from Japan, tied to the rhythms of plantation and community life rather than aimed at anyone outside their own circle.
What this changed for Shinto's spread was the establishment of a pattern that has held ever since wherever the tradition has taken root outside Japan: shrines built by and for an immigrant community, bound to that community's own religious life, rather than an outward facing faith actively seeking new adherents. Hilo Daijingu's founding in 1898 set that pattern in Shinto's very first year of institutional presence in Hawaii.
