Walnut Grove Japanese-American Historic District, Japanese American historic district in Walnut Grove, United States.

The Walnut Grove Japanese-American Historic District is a 5-acre (2.0 ha) district in Walnut Grove, California, rebuilt in 1916 one block north of the old Chinatown after the October 7, 1915 fire. Many buildings are two-story wooden structures with family residences above ground-floor shops, and the district still matches 1920s photographs.

Japanese immigrants began establishing businesses here from 1896 onwards, building a growing community. This settlement existed until 1942, when federal order forced residents to leave.

The district was once the heart of the Japanese community, with temples, language schools, and restaurants serving traditional food. Visitors can still sense how these places shaped daily life for residents.

The district covers about 5 acres (2.0 ha) in Walnut Grove, with the rebuilt 1916 blocks set one block north of the former Chinatown site. Walk it on foot; the two-story buildings keep residences above ground-floor storefronts, so look up as well as at street level. Three wartime fire sites are now community gardens.

After a major fire in 1915 destroyed much of the area, Japanese builders from neighboring communities came to help rebuild. This reconstructed section became known as Kawashimo and shows the community's resilience.
