Check that your campaigns in East Asia show the right text, images, language and landing page to the people they target, from a local home connection.

**Quick answer — How do I verify my ads in Japan or South Korea from abroad?**

Load the page where the ad should appear through a residential IP in the target country, signed out, and record what you see: the ad, its text and images, and the landing page after every redirect. **JapanProxies** sells home-broadband IPs in Japan, South Korea, Taiwan and Hong Kong for these checks, from $2.62 for 1 GB, paid in crypto, no KYC. Use the ad platform's own preview tools first.

## What does ad verification check in East Asia?

- **Delivery.** Does the ad appear for people in the target country, on the right pages and keywords?
- **Creative and language.** Is the Japanese, Korean or Traditional Chinese version shown, with the right images and offer?
- **Landing page.** Does the click lead, after every redirect, to the right local page, in the right language and currency?
- **Brand safety.** Next to which content does the ad appear on local news and portal sites?
- **Misuse of your brand.** Are other advertisers bidding on your brand name or showing copies of your ads in the market?

Each market has its own platforms next to Google Ads: Yahoo! JAPAN search ads through LY Corporation in Japan, Naver and Kakao ads in South Korea. A local residential IP lets you see all of them as a local user does.

## Why use a residential IP for ad checks?

Ad platforms decide what to show from the viewer's location, and the IP address is one of the main signals. A check from your office abroad shows your own country's ads, or none.

A residential IP in the country gives a check close to a local person's view. Under the Media Rating Council's invalid-traffic guidelines, known data-centre traffic is classed as general invalid traffic, so a check made from a server may not show the ad that a person at home would see.

## Which official tools should I use first?

- **Google Ads Ad Preview and Diagnosis** shows your Google search ads for a chosen location and language, without counting impressions.
- **Naver, Kakao and LY Corporation ad systems** give you delivery reports for your own campaigns in Korea and Japan.
- **Your own analytics** shows where clicks come from and which landing pages they reach.

Use a residential IP for what these tools do not show: the live page, with the ad in its real context, including redirects and competitor ads.

## How do I run an ad check with JapanProxies?

1. Pick the country code: `jp`, `kr`, `tw` or `hk`.
2. Use a sticky session per check, such as `USERNAME-country-jp-session-ad01-ttl-30`, so the page, the ad and the landing page load from one IP.
3. Open the page in a fresh browser profile, signed out, with the local language set.
4. Save a screenshot and the final URL of the landing page, with the date, time and session ID.
5. Repeat with a new session ID to see whether the result holds on another local IP.

For in-app ads shown only on mobile networks, a dedicated 4G/5G port in Japan or South Korea is available from $5.93 per day on the [pricing page](https://japanproxies.com/pricing/).

*Playwright (Python): screenshot a page and its landing URL from Japan*

```python
from playwright.sync_api import sync_playwright

PROXY = {
    "server": "http://gw.japanproxies.com:7777",
    "username": "USERNAME-country-jp-session-ad01-ttl-30",
    "password": "PASSWORD",
}

with sync_playwright() as p:
    browser = p.chromium.launch(proxy=PROXY)
    context = browser.new_context(locale="ja-JP", timezone_id="Asia/Tokyo")
    page = context.new_page()
    page.goto("https://YOUR-PUBLISHER-PAGE.example/")
    page.screenshot(path="placement-jp.png", full_page=True)
    # Open your ad's final URL with your own tracking parameters
    # (never the ad server's click link: that counts as a click)
    page.goto("https://YOUR-LANDING-PAGE.example/?utm_source=YOUR_TRACKING")
    print("landing page:", page.url)
    page.screenshot(path="landing-jp.png", full_page=True)
    browser.close()
```

## What should I avoid in ad checks?

- **Do not click ads**, yours or competitors': each click is billed and counts as invalid traffic, and generating clicks is forbidden by our [acceptable use policy](https://japanproxies.com/acceptable-use/). Keep page loads to a few samples per check, since each one can register an impression. To test redirects, use the tracking-template test in the ad platform.
- **Do not sign in** to ad platforms or publisher sites through the proxy on behalf of others.
- **Keep volumes low.** Ad verification is sampling, not traffic generation.

## What does ad verification cost?

A page with ads loaded in a browser often uses two to five megabytes. A weekly sample of a few dozen placements per market fits in 5 GB or 10 GB. One plan covers Japan, South Korea, Taiwan and Hong Kong, and traffic never expires.

| Plan | Quantity | Price | Price per unit |
| --- | --- | --- | --- |
| Test | 1 GB | $2.62 | $2.62/GB |
| Light | 5 GB | $4.95 | $0.99/GB |
| Standard | 10 GB | $6.60 | $0.66/GB |
| Team | 50 GB | $26 | $0.52/GB |

In every plan: Japan, South Korea, Taiwan and Hong Kong · Rotating and sticky sessions · HTTP, HTTPS and SOCKS5 · Traffic never expires

## Ad verification questions

### Can I verify Yahoo! JAPAN and Naver ads, not only Google Ads?

Yes. Load the search or portal page through a Japanese or Korean residential IP and you see the ads those platforms show to local users. Use each platform's own reports for delivery figures.

### Can I check ads in one city, such as Taipei or Seoul?

JapanProxies offers city targeting on every plan: add `-city-taipei` or `-city-seoul` to the username; city availability varies. For an exact location, also use the location setting of the ad platform's preview tool.

### Do I need a mobile proxy for mobile ads?

For ads in mobile browsers, a residential IP with mobile emulation is usually enough. For ads shown only to users on mobile data, use a dedicated 4G/5G port in Japan or South Korea, from $5.93 per day.

### Can an agency check ads for several clients?

Yes. One balance serves several clients and countries. Keep each client in separate sessions and record the session ID with every screenshot.

### Is ad verification allowed under your policy?

Yes, for your own campaigns, your clients' campaigns and brand-protection checks. Generating clicks or impressions is not.
