The solution
Uniqlo's online growth made apparel fulfillment unusually hard: huge SKU variety, variable packaging, returns and a need for fast shipping. More people in aisles would add walking, handling and training cost.
Fast Retailing and Daifuku began the Ariake project in 2016 and announced a strategic global partnership in October 2018 after automating the e-commerce warehouse. Reports said the warehouse could operate 24 hours a day and cut staff by about 90%.
The clever part was not a single robot. RFID inspection, automated storage, goods-to-person picking, box sizing and sorting were wired into one flow, making the garment's identity the control signal for the building.
What it achieved
Let RFID drive the warehouse
Why it worked
RFID let the system verify apparel automatically instead of treating every item as a visual exception.
Goods-to-person flow attacked walking time, one of the quiet costs of e-commerce warehouses.
Box sizing and automated sorting reduced downstream shipping waste and handling.
A strategic partnership with Daifuku turned one warehouse fix into a template for global rollout.
What can be applied
Automation works best when the item, the shelf and the order all become machine-readable parts of one flow.
Aftermath
World Economic Forum, citing Quartz, reported a 90% warehouse staff reduction after automation. Fast Retailing and Daifuku said they would use the Ariake work as the basis for automated brand warehouses in Japan and overseas.
