Scraping marketplaces in Japan — price & assortment monitoring
Products, prices, sellers and ratings from marketplaces in Japan: full catalog or selected categories, one-off or on a schedule.
Marketplaces are the most dynamic corner of e-commerce in Japan: prices and offer sets change many times a day, sellers come and go, the buybox switches hands. Scraping turns that churn into manageable data: you see who sells what, and at what price, in every category.
This list counts 14 stores; the leaders by domain authority: Etsy, Amazon, Rakuten. We collect data from large multi-level catalogs and niche shops alike: everything lands in one structure, so prices and assortment compare directly.
Brands you will meet across these stores include Nintendo, Samsung, Sony, Panasonic, Apple, Sharp. The product-to-brand mapping ships with the data: convenient for distribution control and shelf comparison.
We deliver data the way you need it: one-off price scraping or scheduled refresh, in Excel, CSV, JSON, XML, Google Sheets, REST API or straight into your database. We agree the field structure upfront and send a free sample first.
