The Need for E-Commerce Automation in Japan
Handling orders manually via Excel sheets is not only slow but also prone to human error, which damages customer trust. For global sellers operating across multiple Japanese marketplaces, real-time inventory and order sync is crucial.
At DONOMI, our WMS (Warehouse Management System) and OMS (Order Management System) connect directly to Amazon Japan, Rakuten, and TikTok Shop. Here's how the technical integration works.

1. Amazon SP-API Integration
The Amazon Selling Partner API (SP-API) allows our WMS to:
- Automatically download pending and unshipped orders every 15 minutes.
- Push tracking numbers (Yamato/Sagawa) back to Seller Central once orders are packed.
- Sync inventory levels in real-time, preventing overselling.
- PII Compliance: In line with Amazon SP-API guidelines, we automatically purge Personally Identifiable Information (PII) from our database 30 days after order completion.

2. TikTok Shop & Rakuten API Connectors
For TikTok Shop Japan and Rakuten:
- We establish secure OAuth connections to fetch order details.
- Orders from TikTok live campaigns or affiliate shops trigger immediate picking tickets at our Chiba facility.
- Real-time stock counts are pushed back to prevent cart abandonment due to out-of-stock items.

3. The Client Portal Experience
Sellers from the US, China, and India do not need custom coding. Our Client Portal offers a simple integration panel:
Authorize: Click to connect your seller accounts.
Map: Align your SKUs with the inventory stored in our warehouse.
Monitor: View live shipping progress, return rates, and billing details from a single dashboard.
