Are the search results for your website displaying strange Japanese text? If so, you may be a victim of the Japanese SEO Spam, also known as the Japanese keyword hack. This attack can be a major headache for website owners. It fills your site with spammy, irrelevant keywords, which can severely damage your search engine rankings and reputation. Don’t worry, though. The Hawk Tech is here to help you understand what this is and how to fix it.
What is the Japanese Keyword Hack?
The Japanese keyword hack is a type of SEO spam where a hacker gains unauthorised access to your website. They inject malicious code that creates new, hidden pages or modifies existing ones with Japanese keywords. These pages are designed to trick search engines like Google into displaying spammy content in your search results. The goal is to funnel traffic from your website to the hacker’s malicious sites, often for shady purposes. This not only harms your website’s integrity but also ruins your SEO efforts.

The hack can be hard to spot at first. Your website might look normal to you and your regular visitors. The spam content is often cloaked, meaning it’s only visible to search engine bots. However, if you see Japanese text in your Google search results, you’ve been compromised.
Steps to Fix the Japanese Keyword Hack
Getting rid of the Japanese keyword hack requires a systematic approach. Follow these steps carefully to clean your site and prevent future attacks.
1. Back Up Your Site Before Cleaning
This is the most critical first step. Before you make any changes, you must back up your entire website. This includes all files and your database. A backup ensures that if something goes wrong during the cleaning process, you can restore your site to its previous state. This will prevent any data loss or further damage. You can perform a backup manually, use a plugin, or utilise your hosting provider’s backup features.
2. Check Google Search Console for Unauthorised Users
Hackers often add themselves as administrators to your site. This gives them full control to manipulate settings, including sitemaps and geo-targeting.

- Go to your Google Search Console.
- Navigate to the “Users and Property Owners” page.
- Look for any unfamiliar email addresses, especially spammy-looking Gmail accounts.
- If you find any, remove their access immediately.
This step helps to ensure the hacker can’t regain access after you’ve cleaned the site.
3. Run a Malware Scan
A thorough scan is essential to find and remove the malicious files. You can use your web host’s cPanel ‘Virus Scanner’ or a reliable plugin. We recommend using a professional-grade malware scanner like the Wordfence plugin. Wordfence offers a powerful malware scanner and a web application firewall to help identify and block threats. The Hawk Tech offers technical services that include comprehensive malware scans and removal. This ensures no hidden files are left behind.
4. Check the .htaccess file
The .htaccess
A file is a common target for hackers. They use it to redirect visitors and search engines to their spam websites.
- Locate your
.htaccess
file in your website’s root directory. - Compare its content with a clean version from your backups.
- Look for any suspicious or unfamiliar rules.
- If you find any questionable code, comment it out by adding a
#
character at the beginning of the line.
Hackers may also compromise other core files like index.php
and config.php
. Always check these files for unusual code as well.
5. Replace Core, Plugin, and Theme Files
After identifying the compromised files, the best course of action is to replace them with clean versions.
- Download fresh copies of your WordPress core files, themes, and plugins from their official sources.
- Overwrite the existing files on your server.
- This ensures that any hidden malicious code within these files is completely removed.
This step is a powerful way to eliminate the Japanese keyword hack and other malware that might be embedded in your site’s software.
6. Prevent Future Attacks with a Website Firewall
Once your site is clean, you must take steps to prevent another attack. The Japanese keyword hack is just one example of SEO spam. Others, like the pharma hack, display spammy pharmaceutical products. A website firewall is your first line of defense.
