Kakaku.com Autos Data Parser & API
Kakaku.com Autos is the automotive vertical of Kakaku.com, Japan’s giant price-comparison platform, and Carapis can extract its aggregated new- and used-car pricing, spec and ranking data through one REST API. Where Carsensor and Goo-net are listing portals, Kakaku is a comparison and review aggregator, giving a price-benchmark and spec-catalog view of the Japanese market that Carapis can serve without you building a scraper.
On request — not in the live feed today. We do not continuously crawl Kakaku.com Autos right now. Activation takes 2–3 weeks of engineering and is quoted per source, because each one ships with dedicated proxies, anti-bot tuning and ongoing maintenance. Ask us to add it.

What is Kakaku.com Autos?
Kakaku.com (価格.com) is one of Japan’s largest price-comparison and review sites, spanning electronics, services and automobiles. Its auto vertical aggregates new- and used-car prices, detailed specifications, user reviews and model rankings rather than hosting individual dealer ads in the way a classifieds portal does. That makes it a benchmark/catalog source: a normalized view of model specs and going prices across the Japanese market, drawing on the parent site’s very large audience.
Market Position
Kakaku.com sits beside the big Japanese listing portals (Carsensor ~35.8M/mo, Goo-net ~24M/mo) but plays a different role — comparison and aggregation rather than primary inventory (IGNITE). Its strength is breadth of normalized spec and price-benchmark data and its review/ranking signals, which complement the listing-level data from Carsensor and Goo-net. As an aggregator it is a lighter parse target (priority ★★) but valuable for reference pricing and spec catalogs.
What the API returns
Response schema
Indicative — this is the shape, not a guarantee. Every source returns the same structure, so what you build against does not change when you add one. Which fields carry a value depends on the source and on the individual listing: a site that does not publish mileage returns null there, and Kakaku.com Autos is no exception.
List — GET /apix/api/vehicles/ — returns 30 fields per vehicle:

}Which sources you can actually query is answered by GET /apix/api/sources/ with your API key — it is the list your account can pull today, and it is the one to trust over any page on this site.
Kakaku’s distinctive value is normalized benchmark pricing plus ranking and review signals — a reference layer for calibrating listing-level prices from the portals, rather than raw individual inventory.
