YOKOTA AIR BASE, Japan – In a spotless kitchen on this airlift hub in western Tokyo, cooks are quietly reinventing how American service members eat across Japan’s main island.
For the past year, a pilot program run by the Army and Air Force Exchange Service has been producing frozen, bento-style meals at Yokota – designed to travel far beyond the reach of traditional fresh-food delivery – to remote bases where a hot meal has long been difficult to come by.
The Yokota central flight kitchen turns out between 600 and 800 frozen meals each week. Offerings include chicken teriyaki over rice, karaage, bulgogi, salmon penne and ham-and-cheese burritos, according to Andrew Defelice, general manager at Yokota’s exchange.
The effort relies on blast-chilling, a food preservation method that rapidly cools freshly cooked meals to pass safely through the bacterial danger zone in about 90 minutes. Once sealed, boxed and shipped through the exchange’s distribution system, the meals can be stored for weeks and reheated in minutes, AAFES said.
“Getting fresh, ready-to-go meals for service members at Misawa Air Base has long been a logistical challenge,” Julie Mitchell, vice president of marketing and customer engagement for AAFES, told Stars and Stripes by email Nov. 19.
Misawa, in northern Honshu, is roughly a 10-hour drive from Yokota. Traditional bento meals can be refrigerated for no more than 72 hours, making delivery impractical. Smaller installations, including Combined Arms Training Center Camp Fuji, Yokohama North Dock and Sagami General Depot, often lack the storage capacity for fresh food altogether.
Those constraints pushed Yokota’s airline catering team – a group of 18 employees – to look for alternatives. The idea took shape after Shunichi Kobayashi, the flight kitchen’s manager, attended food conventions in Tokyo and learned about blast-chilling technology widely used in Japan’s commercial catering industry.

What followed was more than a year of planning, according to Defelice. The program required coordination with AAFES food safety officers and inspections by U.S. Army veterinarians, who are also food safety experts that inspect food manufacturing facilities that supply the Department of Defense, according to Public Health Command-Pacific.
Yokota’s central flight kitchen was built in 1960 to support the Patriot Express, charter flights contracted by the Air Force Air Mobility Command to carry Depart of Defense personnel and their families on official moves and travel.
“In November 2024, we got the green light and then we started executing,” DeFelice said during a Dec. 10 tour of the flight kitchen. “We had to do several tests, making samples in different conditions, so this was all made from scratch.”
The pilot began modestly, offering five frozen meal options at Misawa, he said. Early sales hovered around 100 meals per month. Within months, he said, that number more than doubled. Demand is expected to rise further during large military exercises, when dining options can be limited.
The program’s next priority is solidifying its brand image and introducing more commercial packaging for the frozen bento meals targeted for late 2026, DeFelice said.
As the program expanded, freezer-equipped vending machines were installed at Sagami Depot, Camp Fuji and Yokohama North Dock, and most recently at Yokota’s 374th Security Forces Squadron and Medical Group, allowing troops to purchase microwaveable meals around the clock.
“Service members across mainland Japan have 24/7 missions but don’t always have access to fresh food,” Mitchell said. “These meals provide 24/7 convenience.”
