Opening a store on Rakuten is finally not just a dream!
I'd long wanted to expand to Rakuten but was held back by the lack of a Japanese corporate entity. OSL's supporting services made it happen. Beyond solving the qualification hurdle, their system and warehousing-delivery services are outstanding, dramatically lowering our early-stage operating and trial-and-error costs.
The best system for both B2B and B2C
Most overseas warehouses look the same, but OSL is the only one I've found that excels at both sealed full-container forwarding (To B) and store dropshipping (To C). The API is rock solid—orders flow through almost entirely without manual intervention.
The Confidence to Win Price Wars
As our shipping volume grows, OSL's delivery cost-performance advantage becomes ever clearer! Their highly competitive storage fees have helped us keep long-term stocking costs perfectly under control and stay consistently profitable even in fiercely competitive red-ocean categories.
A Complete Logistics Upgrade for Your D2C Store
What worried us most about D2C was last-mile fulfillment. OSL not only supports custom packaging but also connects orders, inventory, and tracking numbers end to end. The customer delivery experience has clearly improved, and repeat purchases are up too.
Outsourcing Japanese customer support was a huge help
Japanese-language customer support was always our weak spot. OSL's dedicated support team responds promptly and communicates professionally—returns processing is much faster, and our store ratings have stabilized considerably.
From warehouse setup to shipping, everything is hassle-free
Once our cargo is inbound in full containers, there's barely anything to manage — transfers to FBA or downstream channels in original boxes run seamlessly. The system data is clear and reconciliation is easy. A key long-term partner for us.
Finally, Accurate Inventory Data
With previous systems, the books never quite reconciled. OSL's cloud system is incredibly precise — inventory data matches physical counts almost perfectly. No more all-nighters doing reconciliation.
Returns Processing, Without the Headache
Return rates among Japanese consumers aren't low, but OSL's returns and exchanges process is remarkably well-organized—returns are inspected and restocked quickly without hurting resale. A huge weight off our minds.
FBA forwarding efficiency beyond expectations
Moving goods from our warehouse to FBA used to be a constant headache. OSL's dedicated direct-truck service solved it — guaranteed arrival within 48 hours, keeping our Prime badge rock-solid.
System integration took just one day
We expected the system integration to take a week or two, but OSL's technical team finished the API integration in a single day—orders syncing automatically, inventory deducting in real time. True professionals.
