Florin is a census-designated place (CDP) in Sacramento County, California, United States.

[3] According to the United States Census Bureau, the CDP has a total area of 8.7 square miles (23 km2), all of it land.

There were 16,070 housing units at an average density of 1,846.6 per square mile (713.0/km2), of which 8,173 (55.2%) were owner-occupied, and 6,631 (44.8%) were occupied by renters.

"In his report to Governor William Stephens, Colonel John P. Irish, president of the California Delta Association, described Japanese triumph: 'They [the Californians] had seen the Japanese convert the barren land like that at Florin and Livingston into productive and profitable fields, orchards and vineyards, and intelligence of their industry.

'"[9] The presence of Japanese immigrants in Florin was not always met with such good will as expressed by Colonel Irish.

"As soon as a Jap can produce a lease," the Sacramento Bee warned, "he is entitled to a wife.

He sends a copy of his lease back home and gets a picture bride and they increase like rats.

Florin [a valley farming town] is producing 85 American-born Japs a year.

Local and federal treatment of Nisei (Japanese immigrants and US-born Japanese Americans) in Florin took a drastic downturn upon the bombing of Pearl Harbor and the subsequent war between the US and Japan.

At the time, about 2,500 Florin residents were Nikkei, forming a majority of the town's population.

Florin Japanese American resident and educator Mary Tsukamoto recalled "everyone was given short notice for removal.

"[12] The Elk Grove Masonic Building referred to by Tsukamoto was located in neighboring Elk Grove near a railroad station where the Florin residents were shipped in rail cars to distribution hubs.

At these distribution hubs Florin's residents of Japanese descent were then sent to internment camps far from the coast.
