## What's an Apify Actor?
Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".
## How to integrate an Actor?
If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.
- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).
For usage examples, see the [API](#api) section below.

# README
## Kakaku.com Scraper — Japan's #1 price-comparison products & prices
Scrape product models from **[Kakaku.com (価格.com)](https://kakaku.com/)**, Japan's #1 price-comparison site. Search any keyword in Japanese or English and get lowest prices, makers, ratings, review counts and specs as clean JSON — no login, no browser, no proxies to configure.
### What you get
```json
{
"name": "iPhone 16",
"maker": "Apple",
"category": "スマートフォン",
"modelId": "M0000001194",
"modelUrl": "https://kakaku.com/keitai/smartphone/model/M0000001194/",
"lowestPriceYen": 112000,
"rating": 4.51,
"reviewCount": 164,
"releaseDate": "2024年9月20日",
"specs": ["6.1インチ", "48MP Fusionカメラ", "eSIM"],
"image": "https://img1.kakaku.k-img.com/images/productimage/ll/M0000001194.jpg"
}
```
Every product model as one row — with the **lowest price across all shops** (numeric yen), maker, category, star rating, review count, release date, key specs and image. This is the data that powers price-comparison and market research in Japan.
### Who uses this
- **Pricing & repricing** — Kakaku is *the* price authority in Japan; track the lowest market price for any product
- **Market research** — ratings and review counts reveal what's popular in each category
- **Brands & manufacturers** — monitor how your products rank and price against competitors
- **Comparison / affiliate sites** — feed a product catalog with real Japanese pricing
### How to use
1. Enter a **keyword** — Japanese or English (`iphone`, `炊飯器`, `ノートパソコン`).
2. Set **Max products** (default 100).
3. Run, then download from the **Dataset** tab as JSON / CSV / Excel, or fetch via API.
### Pricing model
You pay per result — a small fee for each product returned. A 500-product export costs less than a coffee.
### FAQ
**Japanese keywords?** Yes — Kakaku is a Japanese site; both `炊飯器` and `rice cooker` return results. The scraper handles the site's Shift-JIS encoding for you, so text comes back clean.
**What does one row represent?** One product *model* (e.g. "iPhone 16"), with the lowest price aggregated across all shops that sell it — not individual shop listings.
**How fresh is the data?** Live. Every run queries Kakaku in real time.
**Is this legal?** The Actor collects only publicly visible data, the same any visitor sees. It does not log in or access private data. You are responsible for complying with Kakaku's terms and applicable laws.
**Something broke?** Open an issue on this Actor's page — typically fixed within 24 hours.

const input = {
"keyword": "iphone",
"maxItems": 100
};
// Run the Actor and wait for it to finish
const run = await client.actor("youfuxu/kakaku-japan-scraper").call(input);
// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
