## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

## 🇯🇵 Yahoo! Japan Realtime Trends — Live Buzz & Trend Ranking Scraper

Tap into **Japan's #1 real-time trend surface** — the live Yahoo! Japan Realtime ranking (`search.yahoo.co.jp/realtime`) that tells you what 125 million Japanese users are buzzing about *right now*. Every minute, ranked keywords, tweet/buzz volume, genre, and momentum — straight from the source, **no login and no Twitter/X API key required**.

This is data most Western scrapers simply can't touch. Google Trends barely sees inside Japan, and the X API is paywalled into uselessness — so the live Japanese conversation has been a black box for non-Japanese teams. This actor opens it. If you sell into Japan, run a JP brand, trade JP equities, or localize content, this is the untapped early-signal feed your competitors don't have.

### 📊 Sample Output

[![Yahoo Japan Realtime Trends scraper sample output — live trending keyword ranking with rank, keyword, buzz volume and category for Japan real-time trend and buzz monitoring](https://api.apify.com/v2/key-value-stores/8gLgXMBveEI1tTz1z/records/yahoo-japan-realtime-trends-sample)](https://apify.com/nexgendata/yahoo-japan-realtime-trends?fpr=2ayu9b)

Real trends returned by this actor for `{ "mode": "trends", "maxItems": 12 }` — every row below comes straight from a live run:

| Rank | Keyword (trending) | Buzz volume | Category |
|---|---|---|---|
| 1 | 今後の活動 | 26 | — |
| 2 | スガキヤ | 2,358 | food |
| 3 | ココイチ | 167 | アニメ・ゲーム |
| 4 | がたます | 223 | — |
| 5 | ディートリヒ | 284 | — |
| 6 | 秧秧 | 1,212 | アニメ・ゲーム |
| 7 | しいたけ占い | 221 | — |
| 8 | 古賀千景 | 32 | ニュース |
| 9 | 藤丸立香はわからない | 31 | アニメ・ゲーム |
| 10 | 森田浩光 | 24 | entertainment |

> The Realtime board emits the full ranked set (~20 topics plus the hot-buzz carousel) on every run, with live `buzz_volume`, `heat_score`, and genre — so you catch a trend in the minutes it's breaking, not hours later in an aggregated report.

### What you get

Per trending topic, a flat, typed record:

- **Ranking** — `rank` (1 = hottest right now)
- **The trend** — `keyword` (the exact Japanese term Japan is searching)
- **Momentum signals** — `buzz_volume` (tweet/buzz count), `heat`, `heat_score` (0–100 momentum)
- **Classification** — `category`, `category_ja` (food / アニメ・ゲーム / ニュース / entertainment / …)
- **Sub-topics** — `child_buzz[]` (related buzzing terms clustered under the trend)
- **Drill-down** — `url` (the live Yahoo! Realtime search page for that keyword)
- **Provenance** — `snapshot_time`, `data_source`

In `search` mode you instead get the live buzz tweets behind a single keyword — text, author, timestamp, engagement — for sentiment and deep-dive analysis.

### Sample inputs

**1. Live trend ranking (the headline use case)**
```json
{ "mode": "trends", "maxItems": 12 }
````

**2. Full board, deeper pull**

```json
{ "mode": "trends", "maxItems": 30 }
```

**3. Buzz tweets for one keyword (sentiment deep-dive)**

```json
{ "mode": "search", "query": "東京", "maxItems": 40 }
```

### JSON sample record

One representative record, exactly as returned:

```json
{
  "mode": "trends",
  "rank": 2,
  "keyword": "スガキヤ",
  "buzz_volume": 2358,
  "heat": 176,
  "heat_score": 77,
  "category": "food",
  "category_ja": null,
  "child_buzz": [],
  "url": "https://search.yahoo.co.jp/realtime/search?p=%E3%82%B9%E3%82%AC%E3%82%AD%E3%83%A4&rkf=1&ifr=tp_bz",
  "snapshot_time": "2026-06-15T04:45:48Z",
  "data_source": "search.yahoo.co.jp/realtime (buzzTrend)"
}
```

### How it works

Yahoo! Japan builds the Realtime board client-side and ships the ranking as **embedded JSON** inside the page. This actor loads `search.yahoo.co.jp/realtime` through Apify proxy, parses that embedded `buzzTrend` payload directly — no brittle DOM scraping, no headless-browser overhead for the trend board — and emits one clean record per topic. In `search` mode it walks the buzz-tweet feed for your keyword. The `maxItems` cap is a hard ceiling, so compute (and your bill) never outruns what you asked for.

### 🗾 Why this Japanese data is unique

Japan's online conversation runs on its own rails. The dominant search engine is **Yahoo! Japan**, not Google, and its **Realtime** surface is the de-facto pulse of Japanese social buzz — there is no Western equivalent dataset. Google Trends has shallow JP coverage, and the X/Twitter API is now prohibitively gated. That means the signals here — a regional chain like スガキヤ spiking, an anime/game term breaking out, a news name surging — are **invisible to teams relying on US-centric tools**. Getting this in clean structured form, in English-readable fields, is the edge.

### ⚖️ Legal & ToS

This actor reads **only the public Yahoo! Japan Realtime ranking** — the same trend board any visitor sees at `search.yahoo.co.jp/realtime`, no login required. It collects publicly displayed trend metadata (keyword, rank, buzz counts, genre). It does **not** access private accounts, DMs, or anything behind authentication. You are responsible for using the output in line with Yahoo! Japan's terms and your local regulations.

### ❓ FAQ

**Q: Do I need a Yahoo! Japan account or the X/Twitter API?**
A: No. The actor works entirely off the public Realtime board — no login, no API key, no token.

**Q: How fresh is the data?**
A: It's the live board at run time — typically reflecting buzz from the last few minutes. Each record carries a `snapshot_time` so you can timestamp it precisely.

**Q: Why are some trends in Japanese and some in English?**
A: Yahoo! Japan ranks whatever Japan is actually typing — Japanese terms, romaji, brand names, and product names all appear exactly as they trend. We return them faithfully, never translated or altered.

**Q: What's the difference between `trends` and `search` mode?**
A: `trends` returns the ranked board (the keywords buzzing right now). `search` returns the live buzz tweets behind a single keyword you supply — use it for sentiment and deeper context.

**Q: Why did I get fewer items than `maxItems`?**
A: The Realtime board has a finite number of ranked topics at any moment. `maxItems` is a ceiling, not a target — getting fewer is normal, not an error.

# Actor input Schema

## `mode` (type: `string`):

What to fetch. 'trends' returns the live Yahoo! Japan Realtime trend ranking (search.yahoo.co.jp/realtime) - ~20 ranked buzzing keywords plus the hot-buzz carousel, each with tweet/buzz volume, genre and momentum. 'search' returns the live buzz tweets for a specific keyword (requires the query field).

## `query` (type: `string`):

Keyword to fetch real-time buzz tweets for, used only when mode=search. Japanese or English. Example: 東京, AI. Ignored in trends mode.

## `maxItems` (type: `integer`):

Maximum number of records to return. In trends mode the Realtime board emits ~20 ranked topics (plus a handful of hot-buzz keywords); in search mode each page yields up to ~40 buzz tweets. Set to 15 for a quick smoke test.

## `proxyConfiguration` (type: `object`):

Apify proxy configuration. Defaults to Apify's automatic proxy selection, which works for these Yahoo Japan Realtime surfaces from most regions; the actor automatically falls back to residential and then direct fetch if a tier returns no data.

## Actor input object example

```json
{
  "mode": "trends",
  "query": "東京",
  "maxItems": 30,
  "proxyConfiguration": {
    "useApifyProxy": true
