About this Gig
I help overseas sellers and developers get clean product data out of Japanese marketplaces.
Japan is a huge sourcing market, but the sites are Japanese-only and the APIs are documented in Japanese. I am a Japanese developer who runs my own eBay export business and built an eBay listing automation SaaS, so I work with this data every day.
WHAT YOU GET
- Product title, price, stock status, image URLs, shipping cost and item URL
- Delivered as CSV, JSON or Excel, ready to import
- Rakuten and Yahoo Shopping via official APIs. Mercari, Rakuma and Yahoo Flea Market via extractors I already run in production
- Premium: a reusable Python script, so you can re-run it yourself anytime
WHY THIS IS DIFFERENT
Most scrapers break when a page layout changes. For Rakuten and Yahoo Shopping I use the official APIs, so the data stays stable and legitimate.
TYPICAL USES
- Sourcing research for eBay, Amazon or Shopify
- Price and stock monitoring
- Building a product database
Just send me a category URL or a search keyword. I will confirm the fields with you before I start.

FAQ
Which Japanese marketplaces do you support?
Rakuten and Yahoo Shopping through their official APIs. I can also handle Mercari, Rakuma, Yahoo Flea Market and SNKRDUNK using extractors I already run in production. If you need a site not listed here, message me first and I will confirm before you order.
Is this legal?
For Rakuten and Yahoo Shopping I use the official public APIs, exactly as intended. I only collect public product information: titles, prices, stock, images and shipping. I do not collect personal data, emails or contact details.
What do you need from me to get started?
Just three things: the marketplace you want, a category URL or search keyword, and the output format (CSV, JSON or Excel). The order form covers all of it. If anything is unclear I will ask before I start, not after.
Can the data be updated automatically?
Yes. The Premium package includes a reusable Python script you can run yourself anytime. If you want it to run on a schedule and export automatically, message me and I will quote a custom offer.
Do you speak English?
I am a native Japanese speaker and my written English is basic, so I keep communication short and clear. That is exactly why my packages have fixed scope and a structured order form: you get an accurate delivery without long back-and-forth. Technical questions about the data are always welcome.
