Business Description
Manages the Merchandising of the Group
The reason why COLOWIDE Group manages to provide our customers with goods at an appropriate price is because we have managed to create group synergies and provide differentiated value for each brand by establish- ing our own unique merchandising strategy.
COLOWIDE MD acts as the key of the group that supports the backyard, the development, procurement, manufac- turing and distribution of goods and acts as the central nerve system of the group's merchandising.
This way, we can provide safe and secure ingredients, and quickly tailor products to meet the needs of our brands and their menus. As a means of aiming to maximize value to customers and group profits, we will continue to use the combined purchasing power of our group, reduce prices through in-house production, and maintain high levels of security and safety.Group Company

Business Description
Based on the philosophy of “full participation and equality in society for people with disabilities,” the Colowide Group established the special subsidiary Cocot in 2007.
At Cocotte, employees with disabilities, like other employees, demonstrate their individual abilities and engage in a wide range of tasks daily.
At the Yokohama office, they handle tasks such as creating and printing promotional materials used in group stores, and preparing data reports on electricity, gas, and water usage for submission to government agencies. Additionally, at the Cocot offices located within the central kitchens in Kanagawa and Nagahama, they are responsible for cleaning cut vegetables, equipment, and containers, peeling vegetables like radishes, inspecting products, and weighing ingredients.
In this way, Cocot expands the fields where people with disabilities can thrive and fulfills its role as a member of society.
