A product arrives with just a click of a button. Do you know the reality behind this convenience?
Bunkyosha Co., Ltd. (Minato-ku, Tokyo; President: Shuji Yamamoto), in collaboration with JP Rakuten Logistics Co., Ltd. (Chiyoda-ku, Tokyo; President: Takeshi Sugizaki), has produced a booklet for children titled 'JP Rakuten Logistics x Unko Drill: Secrets of the Warehouse.'
This booklet introduces how products ordered from online shops reach customers and the 'warehouses' and 'logistics systems' behind them through humorous stories and quiz formats. Through the logistics system that connects online shop orders to delivery, children can learn about the flow of how things arrive and the importance of jobs that support our lives.
■ Behind the Finger-Tip Delivery
With one button, a product arrives. What happens behind that ordinary scene? When you run out of toilet paper and order online, it arrives immediately. Unko-Sensei asks, 'Do you know the secret behind that convenience?' What spreads there is a massive warehouse and a non-stop system. Products keep moving, supported by people, until they finally reach us. The story begins with a pinch that everyone has experienced.
■ A Large-Scale System Moving in a Massive Warehouse
The logistics warehouse depicted in the booklet is on an unimaginable scale. Its area is equivalent to about 160 twenty-five-meter swimming pools. A vast number of products are stored there and quickly retrieved according to orders. Products are automatically carried to shelves, move when needed, and are shipped. Furthermore, the conveyor belts running through the warehouse reach about 8,000 meters when connected. Such systems support our 'immediate delivery.' It's a warehouse capable of storing 10,000 years' worth of toilet paper, assuming you wipe every day.
■ A Logistics Site Created by People and Technology
On the other hand, this world is not moved by machines alone. People handling products, people arranging deliveries, technicians protecting equipment, and people organizing the overall flow based on data—each plays a role and works together. Behind a single product arriving, many people's work is stacked. Through this, the booklet conveys the perspective that 'society is supported by many people.' Various professionals support the logistics site.
■ A System Supporting Life from Behind the Scenes
An era where shopping can be done with one finger. However, behind it exists a large flow for storing, moving, and delivering products. Warehouses and people working there are usually unseen. Our lives are possible because of their existence. This booklet provides children with an opportunity to notice these 'invisible systems.'
■ About Unko Drill
