Get structured data from 価格.com (Kakaku.com), Japan's largest price-comparison marketplace, covering electronics, appliances, computers, and general goods. Give this Actor a category path or a search keyword and it returns one row per product: name, category, lowest price, star rating, review count, and a link to the listing. Every product also comes with a full price breakdown across every retailer selling it, plus the complete spec sheet Kakaku publishes for that item. Built for price monitoring, competitive intel on Japanese retail, and sourcing research, without opening one product page at a time.

🔍 What does Kakaku Scraper do?

This Actor pulls product data from 価格.com (kakaku.com) by category or by search keyword.

Give it one or more category paths, such as pc/note-pc for laptops, or a list of search keywords, and it returns every matching product: name, category path, lowest price, star rating, review count, and a link to the product page. For each product it also returns a full retailer comparison row for every store selling that item (retailer name, price, and whether it's the cheapest offer), plus every published spec as its own row. It runs on the Apify platform with scheduling, integrations (Make, Zapier, Google Sheets), and run monitoring built in.

• I am a reseller sourcing from Japan looking to compare retailer prices for the same product in order to find the cheapest supplier before I buy.
• I am a market researcher tracking Japanese consumer electronics trends in order to see how prices, ratings, and retailer counts shift across categories over time.

✨ Tips

• Start with a low maxItems while testing a new category, then raise it once you know what it returns.
• Batch several category paths and search keywords into one run instead of starting a new run for each one.
• Use maxPages to control how deep a category run goes; search keywords only return one page regardless of this setting.
• Re-run categories you care about on a schedule to catch price changes as retailers post them.

❓ FAQ, disclaimers, and support

価格.comから商品データを取得するには？ Add your category paths or search keywords to the input and run the Actor. It returns every matching product with its lowest price, retailer comparison, rating, and specs.

Does this get me every retailer selling a product? Yes. Every product row comes with a matching set of retailer comparison rows, one per store Kakaku lists as selling that item, each with its own price and whether it's the cheapest.

Does it get blocked while scraping Kakaku.com? No blocking was observed in testing. The default proxy setting has run cleanly across category, search, and product pages.

Does it extract private customer data? No. This Actor only collects public listing data that Kakaku.com shows to any visitor: product names, prices, ratings, and specs.

How fresh is the pricing data? Every run fetches live pages at the time it runs, so prices and retailer counts reflect what Kakaku.com shows that moment.

Why don't some products have a lowest price? A small number of listings, such as discontinued products, have no active retailer offers. Those rows leave the price fields out rather than showing a stale or fabricated number.

Is scraping Kakaku.com product data legal? This Actor collects publicly available listing data. You are responsible for complying with Kakaku.com's Terms of Service and applicable laws in your use of the data.
