Diet Cook Supply

What Diet Cook Supply does

Diet Cook Supply is a Japanese food manufacturer headquartered in Fukuyama, Hiroshima, that produces healthy salads, prepared foods, and processed vegetable products. The company was founded in 1997 and is a subsidiary of Kenko Mayonnaise Co., Ltd., benefiting from the parent group's established distribution and corporate infrastructure. Its core technical capability centers on potato-based processing and proprietary freezing technology, with a distinctive sourcing model that upcycles off-spec and surplus vegetables from local farmers into finished food products.

The company operates the Fukuyama Factory Manager sub-brand, which has received the Hiroshima Governor's Award (2020) and Fukuyama Brand designation (2022), and its upcycled product line was recognized with the Social Products Award (2025). Distribution is multi-channel: wholesale to supermarkets (leveraging the Kenko Mayonnaise network), direct-to-consumer e-commerce, restaurant partnerships (including Café Boneu), regional retail (Halows, added in 2025), and event-based sales. R&D collaboration with Fukuyama University (2025) extends its product development pipeline.

The business model is a hybrid B2B/B2C manufacturer: revenue is generated primarily through wholesale unit sales of salads and processed vegetable products to supermarket chains and food service partners, supplemented by DTC online sales and branded sub-brand offerings. The company has reported nine consecutive years of new graduate hiring and supplements its workforce with Vietnamese technical intern trainees, indicating stable, self-funded growth within the Kenko Mayonnaise Group umbrella. No external funding rounds, M&A activity, or disclosed financial figures are present in the source material.

Directly comparable to Diet Cook Supply's vegetable-forward prepared foods and tomato-based upcycled SKUs and shares the retailer and foodservice distribution channels.
