📋 Overview

Kakaku.com (価格.com) is Japan's #1 price-comparison site — around 74 million visits a month — and this Kakaku product scraper turns it into structured data on demand. Because Kakaku compares every shop selling a product, each record carries the complete per-shop price list — every retailer's price, shipping, payment methods and comment — plus the lowest and highest price across the whole market. Pick a category, choose your depth, and download a clean spreadsheet of prices, specs, ratings and rankings.

Why thousands of professionals choose us:

You get the whole market in one row.

🐛 Troubleshooting

No results returned

• Make sure you provided at least one valid category slug (e.g. kaden/lcd-tv) or an itemlist.aspx URL.
• Widen your minPrice/maxPrice band — tight filters can exclude everything.
• Double-check the category path matches a real Kakaku category.

Fewer results than expected

• Check maxResults — on the FREE tier it caps at 40 products per run.
• Some categories simply have a small catalog on Kakaku.

Missing per-shop prices, specs or breadcrumbs

• Those fields are populated in Detail mode only. Switch scrapeMode to detail.

Not sure which category slug to use

• Open the category on kakaku.com and copy the path after the domain (e.g. kaden/lcd-tv), or paste the full itemlist.aspx URL — the actor accepts either.
