If our system stops, items purchased through e-commerce will not be delivered, and the only direct contact with customers is \"logistics (delivery)\". Logistics has a strong impression of being behind the scenes, but it plays such an important role.\nIn addition, while managing these systems close to the \"site (warehouse)\", the control of the \"estimated delivery date\" displayed on Rakuten Ichiba, the \"delivery status display\" from the purchase historyon Rakuten Ichiba, and the \"delivery related notification\" are also part of the system that our department is in charge of.\nIn this way, we, the EC Logistics Development Department, develop and operate the \"logistics\" that support the Rakuten Group and the \"systems\" that support it in general.\nECLD's Mission:\nWe contribute to the growth of our stakeholders by leveraging our expertise and systems.\nContributing to the advancement of our stakeholders is both a joy for ECLD and a way to demonstrate our organizational value.
