Marutori Keiran

Marutori Keiran's journey began with "Marutori Shirai Shoten," established in 1937. Expanding its business areas into pack eggs, liquid eggs, and frozen eggs in line with postwar changes in eating habits, it has now built an integrated production system with a GP center and liquid egg factory on the headquarters site. While introducing the latest equipment such as Sanovo continuous sterilization devices and egg-cracking machines, the company carries on the founding spirit of "delivering fresh eggs to the region."

Because eggs are natural foods, even slight changes in temperature, humidity, and hygiene environment directly affect quality. Marutori Keiran strictly controls the rearing environment and feed safety at designated farms, while also maintaining temperature management, washing, sterilization, and inspection systems within the factory. On each line for liquid, frozen, and pack eggs, the company works daily on preventing foreign matter contamination, maintaining freshness, and thoroughly enforcing hygiene standards.

In addition to commercial supply to school lunch centers and baking / confectionery manufacturers, the sterilized frozen whole egg "Rakuchin Tamago®" was born from the desire to have households use professional-grade egg products too. The online shop offers sets in multiple sizes, and YouTube and recipe pages introduce easy arrangements such as soups, chawanmushi, and French toast. By delivering safe and easy-to-use egg products from Toyohashi to dining tables nationwide, the company supports daily cooking and confectionery making.
