Ahjikan was founded in Hiroshima in the 1960s with a focus on ready-to-eat meals such as boxed lunches, prepared side dishes and semi-cooked dried and frozen foods. Their most well-known products are their egg products, like their frozen tamagoyaki which are available in supermarkets across Japan.

Besides frozen foods, they produce a range of health foods derived from burdock root. Their gobocha burdock root tea is known for being a cleansing, caffeine-free beverage which is high in dietary fiber.
