Rock Field Co., Ltd. manufactures and sells salads and other deli foods as ‘The Mirai Salad Company’. In 1965, when founder Iwata was 25, he opened “Restaurant HOOK” in Kobe Nankinmachi as the company's predecessor. In the years after when visiting Europe and the United States, Iwata saw potential in delicatessens and founded Rock Field Co., Ltd. in June 1972. After its establishment, we opened shops mainly in department stores. Since around 2000, we have expanded to shops inside of stations and buildings. Currently, there are approximately 320 stores in Japan, 2 stores in Shanghai, and 4 stores in Hong Kong.

We have been committed in pursuing the value of rich foods while promoting a new Japanese food culture, particularly through salads. We are dedicated in creating a rich future with unprecedented salads by re-examining the possibilities of traditional Japanese food while focusing on health, safety and security.

Q. What are you recently focused on or what new ideas do you have for the future?

We focus on selling salads using cooked vegetables, as well as salad kits using both fresh and cooked ingredients that allow customers to enjoy the experience of serving. At our Shizuoka factory, a fourth building is scheduled to be completed in May 2020 which utilizes further mechanization and automation to save labor and features a restructured production line for expanding into new markets. In addition, by maximizing the power of each ingredient, we hope to offer competitive products.

Q. Do you have any memories from working with LUMINE that you would like to share?

Our first experience working with LUMINE was at LUMINE Ogikubo in 2000. In 2001 when we opened a store at LUMINE Shinjuku 2, LUMINE was empathetic in creating a store that we envisioned and helped us by deregulated which left a strong impression on our company. As a result, we felt great potential in opening stores within train stations. In a time when the concept of ‘ekinaka’—the shopping area inside of a station—did not yet exist, we are grateful for the opportunity given to expand stores.

Q. Do you have any messages to your overseas customers/companies?

Focusing on the ‘health, safety and security’ aspects of salads, we hope to further promote the Japanese food culture not only in Japan but also overseas.
