On a Saturday morning the food court at Mitsuwa Marketplace on Culver Drive fills with a particular kind of family: a father in a company polo, a mother steering a cart of Japanese pantry staples, two children who switch between English and Japanese without seeming to notice. They are part of the Japanese community in Irvine, a quiet, largely corporate population that has made this master-planned Orange County city one of the most comfortable landing places in America for a family sent over from Tokyo or Hiroshima.
It is not a Japantown in the old sense. There is no historic main street, no pre-war farming district, no temple founded by Issei pioneers. Irvine’s Japanese story is newer, cleaner, and built almost entirely around two things that drew the rest of Irvine too: good companies and very good schools.
The Place
Irvine sits in central Orange County, roughly halfway between Los Angeles and San Diego, on land that was once one of the largest private ranches in California. The 185-square-mile Irvine Ranch was assembled in 1864 from three Mexican land grants and incorporated as the Irvine Company in 1894, and for most of the next century it grew cattle, citrus, and lima beans rather than houses.
The city as it exists now was drawn on paper. Beginning in the late 1950s, architect William Pereira and Irvine Company planner Raymond Watson laid out a grid of residential “villages” separated by six-lane arterial roads, with greenbelts, commercial centres, and an industrial zone all assigned their place. Irvine was formally incorporated on 28 December 1971.
The result is a city of more than 300,000 people that is consistently ranked among the safest of its size in the United States, with schools to match. For a Japanese executive weighing a three-year posting, that combination is close to decisive.
How It Became Japanese
Irvine’s Japanese presence was not born of refugee flight or chain migration in the usual sense. It arrived in the cargo of corporate expansion, and it followed the companies that planted their North American flags along the San Diego Freeway in the 1980s.
The corporate arrival
The anchor tenant, in every sense, is Mazda. Mazda North American Operations has occupied its headquarters at 7755 Irvine Center Drive since 1987, after relocating from Compton, and the campus employs roughly a thousand people. With a corporate headquarters comes a steady rotation of Japanese managers and engineers posted from the parent company in Hiroshima, each typically arriving with a spouse and children for a posting of a few years.
Mazda was not alone. Toshiba established an Irvine campus in 1987 as the United States headquarters of its information equipment business, and over the years units of Mitsubishi, Ricoh, Toyota, and TDK joined the cluster. An Orange County Business Journal survey counted 107 Japanese firms in the county employing some 16,500 people, and Irvine consistently came out on top as the preferred address.
The expat family pattern
What the companies created was a distinctive demographic: the chuzaiin, the sent-over employee, and his family. These households are different from the older Japanese American communities of Los Angeles County. Many are not immigrants at all but temporary residents, kaigai chuzai families who expect to return to Japan and who organise their American years around keeping their children fluent and on track for Japanese schooling back home.
That expectation shaped the institutions that grew up around them. Saturday Japanese schools, Japanese grocers, Japanese pediatric and dental practices, and Japanese-speaking real estate agents all clustered to serve a population that needed Japan reproduced, carefully and temporarily, in Orange County.
Schools as the deciding factor
If the companies brought the families, the schools kept choosing Irvine over the alternatives. The Irvine Unified School District is the only district in Orange County to have every one of its comprehensive high schools ranked in the top five per cent of California schools by U.S. News & World Report. University High School and Northwood High School in particular draw families who will commute and pay premiums to be inside their attendance boundaries.
For a Japanese family that may return home in three years, the math is straightforward. The child attends a strong Irvine public school on weekdays and a Japanese supplementary school on Saturday, and arrives back in Japan having lost neither track. Irvine made that double life unusually easy to lead.
From scattered farms to corporate suburb
It is worth noting what came before. Orange County once held small, scattered settlements of Japanese farming families, part of the broader agricultural diaspora that shaped places like nearby Gardena and Garden Grove. Irvine’s modern Japanese community has little institutional continuity with those pre-war farmers. It is a separate, later story, written in office leases rather than crop rows, and it sits alongside Irvine’s much larger Chinese, Korean, Persian, and Vietnamese communities rather than displacing any of them.
The Landmarks
Mitsuwa Marketplace, 14230 Culver Drive. The Irvine branch of the national Japanese supermarket chain opened in 2011 and functions as the community’s living room. Its food court serves house-made udon, ramen, and freshly cut sushi, and weekends bring out the expat families restocking on Japanese pantry goods they cannot find elsewhere.
Mazda North American Operations, 7755 Irvine Center Drive. The headquarters that arrived in 1987 is the gravitational centre of corporate Japanese Irvine. Its presence, and the steady rotation of Hiroshima staff through it, helped make the city a default destination for Japanese postings across Southern California.
Mitsuwa Marketplace, 665 Paularino Avenue, Costa Mesa. Just over the Irvine line, the Costa Mesa store dates to 1989, when it opened under the Yaohan name before the chain was rebranded as Mitsuwa in 1998. For Irvine families it is the larger sibling, often hosting Japanese gourmet fairs and pop-up vendors flown in from Japan.
Orange Coast Gakuen. One of the oldest and largest Japanese language schools in Orange County, running classes from preschool through high school. The school notes that the majority of its families live in Irvine, Huntington Beach, and south Orange County, a fair summary of where the region’s Japanese households have settled.
Orange Gakuen, Irvine. A Japanese language school based in Irvine itself, with classes spanning infants through adults and a focus on conversation and culture. It serves both the temporary expat families keeping their children fluent and longer-settled residents wanting to pass the language down.
Diamond Jamboree, Alton Parkway at Jamboree Road. The dense Asian dining centre is not exclusively Japanese, but its mix of ramen counters, teppan rooms, and izakaya-style restaurants makes it a regular weeknight stop for Japanese families who want a taste of home without a long drive.
Irvine Spectrum Center. The open-air mall built in 1995 on the city’s south-east edge is the closest thing Irvine has to a town square, and on weekends it draws the same expat families who shop at Mitsuwa, a reminder that this community lives inside mainstream Irvine rather than apart from it.
Where They Came From
Unlike communities built by chain migration from a single home village, Irvine’s Japanese population is drawn from wherever its anchor companies are based. Mazda’s people come largely from Hiroshima Prefecture, home to the carmaker’s headquarters. Toshiba, Ricoh, Mitsubishi, and the rest pull from Tokyo and across the Japanese industrial map.
The common thread is not geography but situation. These are corporate families on assignment, joined over the decades by a smaller number of Japanese professionals, entrepreneurs, and retirees who came for the same reasons and chose to stay. The 2020 Census counted roughly 8,000 residents of Japanese descent in Irvine, a modest share of the city’s very large Asian population but a settled and visible one.
Irvine Today
The Japanese community in Irvine today is small relative to the city’s other Asian groups, and it can be easy to overlook. With roughly 8,000 Japanese residents inside a city whose population is nearly forty-five per cent Asian, this is not the demographic that defines Irvine’s restaurants or its politics. The Chinese and Korean communities are several times larger.
What the Japanese community has instead is durability and infrastructure. The grocers, the Saturday schools, the Japanese-speaking professionals, and the corporate campuses form a self-sustaining ecosystem that has outlasted the original wave of 1980s arrivals. Families cycle home to Japan, new ones replace them, and the institutions remain.
It remains, in the end, a community defined by Irvine’s own logic. People came for the companies and the schools, found the safety and order that the master plan promised, and built just enough of Japan into the suburb to make the years away from home feel less far. For more on the wider Southern California Japanese story, see our pieces on the Japanese in Torrance, on the Japanese in Sawtelle, and on the Japanese in Gardena. Irvine’s Japanese families share the city, too, with its Vietnamese, Korean, and Persian neighbours.
Frequently Asked Questions
Why is there a Japanese community in Irvine, California?
The Japanese community in Irvine grew up around corporate headquarters that opened in the 1980s, most notably Mazda North American Operations, which has been at 7755 Irvine Center Drive since 1987, along with Toshiba and other firms. These companies rotate Japanese managers and engineers through Irvine, and the city’s safe streets and top-ranked schools have kept it the preferred base for Japanese families in Orange County.
How many Japanese people live in Irvine?
The 2020 Census counted roughly 8,000 residents of Japanese descent in Irvine. That is a modest share of the city’s very large Asian population, which makes up close to forty-five per cent of all residents, and is smaller than Irvine’s Chinese and Korean communities.
Where do Japanese families in Irvine shop for groceries?
The main hub is Mitsuwa Marketplace at 14230 Culver Drive in Irvine, which opened in 2011, with a larger Mitsuwa branch just over the line in Costa Mesa at 665 Paularino Avenue that dates to 1989. Both carry Japanese pantry goods and run food courts serving ramen, udon, and sushi.
Are there Japanese schools in Irvine?
Yes. Orange Gakuen runs Japanese language classes in Irvine for ages from infants through adults, and Orange Coast Gakuen, one of the oldest and largest Japanese schools in Orange County, draws most of its families from Irvine, Huntington Beach, and south Orange County. These Saturday schools help corporate families keep their children fluent for an eventual return to Japan.
What companies bring Japanese workers to Irvine?
Mazda North American Operations is the largest anchor, employing about a thousand people at its Irvine headquarters. Toshiba opened an Irvine campus in 1987, and units of Mitsubishi, Ricoh, Toyota, and TDK have also operated in the area, part of more than a hundred Japanese firms counted across Orange County.
How is Irvine’s Japanese community different from Little Tokyo or Gardena?
The Japanese community in Irvine is largely corporate and relatively new, built around executives on temporary postings rather than the pre-war immigrant farmers and Issei pioneers who shaped Little Tokyo, Gardena, and Torrance. Many Irvine families expect to return to Japan, so the community is organised around schools and grocers rather than temples and a historic main street.
