Jim Nakano and the 1972 founding
Jim Nakano grew up in the Los Angeles area and entered the donut business in the 1960s, working at several Southern California donut shops before deciding to open his own operation. The 1970s were a boom era for Southern California donut shops — a wave of Cambodian immigrants began entering the donut business in the late 1970s, eventually building the dense network of independent neighborhood donut shops that defines greater Los Angeles to this day — but Jim's 1972 opening of The Donut Man came slightly before that broader Cambodian-American donut wave and was driven by his own pre-existing experience in the trade.
The choice of the Glendora location on East Route 66 was practical. By 1972 Route 66 had been substantially bypassed by Interstate 210 to the north for through traffic, but the old highway alignment remained the primary commercial artery for Glendora's eastern edge and adjacent foothill communities. A walk-up donut shop on a busy local road, near several schools and residential neighborhoods, was a sensible neighborhood business model. The original storefront was modest and the early menu was conventional — yeast-raised glazed, cake donuts, old-fashioneds, twists, the standard repertoire of a 1970s Southern California donut shop.
The strawberry donut emerged from Jim's experimentation with seasonal ingredients in the early years of the shop. California's strawberry season — typically running from late February or March through May or June, with peak quality in April and May — produces some of the best fresh strawberries in the United States, and Oxnard and the surrounding Ventura County coastal plain is one of the largest commercial strawberry-growing regions in the country. Jim's strawberry donut took the abundance of nearby California strawberries and applied them in an unusually generous way: a yeast-raised glazed donut sliced open and stuffed with multiple whole fresh strawberries, glazed again, served the same day. The combination of soft yeast donut, sweet glaze, and tart-sweet ripe California strawberries became a regional sensation across the 1970s and 1980s.
