In recent years mobile grocery service that delivers goods to family members living far away in depopulated areas without grocery stores has increased. Many consumer co-ops in Japan including Co-op Sapporo are engaged in this kind of business.

A diet survey conducted in the sparsely populated areas in Japan for elderly citizens revealed that the nutrients in the food for those using the mobile grocery service fall short to those using regular stores.

In response to the results, Co-op Sapporo with the cooperation of Otsuka Pharmaceutical company (Tokyo) and Shikoku University started a “simple nutrition check service” for the grocery service users via Otsuka’s exclusive tablet terminal in May 10 2016.

By inputting answers to simple questions such as:, "how many times in a week they use milk or eat dairy products”, or “whether they cannot eat as a result of dental treatment or lowering of bite force”, the system works to reveal any shortages in the protein level or insufficient vitamin of the user using the screen and voice guidance of the tablet that has been handed to the driver during the delivery rounds.

With this system in place the co-op is able to introduce food products through learning sessions and suggests menu examples that could help improve the eating habits of users.

Users with nutrients deficiency are given leaflets and flyers that introduce foods that contain sufficient nutrients.
