Japan's nine major makers of processed foods and dairy products say they will start discussions on a joint delivery system, amid a truck driver shortage in the logistics industry.

The companies make items such as ham, sausages, cheese and raw noodles. Their products have a limited shelf life ahead of their expiration dates, and their delivery systems require strict temperature control.

An official of Nissin Chilled Foods said the foodmakers will "work to realize a sustainable logistics system for chilled foods that involves the entire supply chain."

The companies plan to ask supermarkets and convenience stores to place orders in large lots, to help improve efficiency of each delivery.

They will also request clients to allow more time for deliveries after placing orders.

The nine companies aim to coordinate sharing trucks and logistics centers such as warehouses, and launch joint delivery services by 2030.
