Not content with being Japan's No. 1 online shopping mall, Rakuten have announced plans to up their game even more by offering same-day shipping to their 50 million strong customer base. This move comes as a challenge to rivals Amazon, who already offer a similar service called oisogi bin (speedy delivery) to customers in the Kanto and Kansai region.

According to Asiajin, up till now Rakuten’s business model has been a B2B2C (business to business to customer) model, but the new warehouses, due to be set up across the country, will streamline their operating systems, allowing Rakuten to make sure that goods are sent on the same day they are ordered.

The first warehouse is planned to be constructed in Chiba (presumably to serve Tokyo) this autumn, but Rakuten doesn’t only plan to offer this service to metropolitan areas, a further five other centers will follow over the next three years, which will also be able to service rural customers. The service may also push down delivery costs as items bought from separate Rakuten stores could easily be parcelled together.
