We use trucks equipped with two temperature zones partitioned to separate chilled products* from unchilled products, making it possible to more efficiently transport both in one vehicle. We have also adjusted the delivery frequency for daily necessities, processed foods, and frozen foods. These initiatives have facilitated a reduction in daily average deliveries per store (excluding newspapers, books, magazines and cigarettes) to 7.0, from 16 in 1989.
*Chilled products: Rice dishes, dairy products, desserts and other items that must be kept refrigerated.

Average Daily Deliveries Per Store

We have equipped our delivery trucks with eco-tires to improve their fuel economy. Trucks delivering chilled products or daily necessities are connected to a traffic control system that helps promote efficient driving and prevent unnecessary idling to reduce emissions of greenhouse gases and air pollutants and to save fuel.

Eco-Tires

Thanks to innovations in tire shape and rubber composition, eco-tires help reduce energy loss (rolling resistance) during use and thus reduce fuel consumption. The use of eco-tires is estimated to improve per-vehicle fuel efficiency by about 4%.

Traffic Control System

This system provides real-time information about the temperature of goods during transportation as well as about arrivals and deliveries, enabling more robust quality control. It also provides data on the ways trucks are being driven, including rapid acceleration and braking as well as speeding. We use this information to promote more efficient driving and to help prevent unnecessary idling.
