The Japan virus belongs with the ransomware type of infection. Malware of such sort encrypts all the data on your PC (images, documents, excel sheets, music, videos, etc) and adds its specific extension to every file.
What is known about the Japanvirus?
☝️ A strictly accurate denomination for the Japan is “a ransomware infection”.
Japan will append its specific .japan extension to every file’s title. For instance, an image entitled “photo.jpg” will be changed to “photo.jpg.japan”. Likewise, the Excel sheet named “table.xlsx” will be changed to “table.xlsx.japan”, and so on.
The ransom note most probably contains a description of how to buy the decryption tool from the racketeers. You can obtain this decoding tool after contacting [email protected], [email protected] by email. That is it.

The note accompanying the Japan ransomware provides the following dispiriting information:
OH NO. YOU ARE HACKED! ALL YOUR PERSONAL FILES HAVE BEEN ENCRYPTED. IF YOU WANT RESTORE YOUR DATA, YOU HAVE TO PAY! Contact us: :[email protected] [email protected] BTC Address: 344BLDIUQMBQH58YZNUTBR3ZYNVGNJJET1 Amount: 0.05BTC
In the screenshot below, you can see what a directory with files encrypted by the Japan looks like. Each filename has the “.japan” extension added to it.
How did Japan ransomware end up on my PC?
There is a huge number of possible ways of ransomware infiltration.
Nowadays, there are three most exploited methods for malefactors to have ransomware planted in your digital environment. These are email spam, Trojan injection and peer file transfer.
If you access your inbox and see emails that look like familiar notifications from utility services providers, delivery agencies like FedEx, web-access providers, and whatnot, but whose mailer is unknown to you, be wary of opening those letters. They are very likely to have a harmful file attached to them. So it is even riskier to download any attachments that come with letters like these.
As for the peer file transfer protocols like torrent trackers or eMule, the danger is that they are even more trust-based than the rest of the Web. You can never guess what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is a good idea to scan the folder containing the downloaded objects with the anti-malware utility as soon as the downloading is done.
How to remove the Japan virus?
It is crucial to inform you that besides encrypting your files, the Japan virus will most likely deploy the Azorult Spyware on your PC to get access to credentials to various accounts (including cryptocurrency wallets). The mentioned spyware2 can derive your credentials from your browser’s auto-filling data.
Often racketeers would decode some of your files to prove that they do have the decryption program. As Japan virus is a relatively recent ransomware, anti-malware designers have not yet found a method to undo its work. Nevertheless, the decoding instruments are constantly upgraded, so the solution may soon be available.
Of course, if the hackers succeed in encrypting someone’s critical data, the hopeless person will most likely comply with their demands. Nevertheless, paying to racketeers does not necessarily mean that you’re getting your files back. It is still risky. After getting the ransom, the racketeers may send a wrong decryption code to the victim. There were reports about malefactors simply disappearing after getting the ransom without even bothering to reply.
The best countermeasure to ransomware is to have aan OS restore point or the copies of your critical files in the cloud disk or at least on an external disk. Of course, that might be insufficient. The most crucial thing could be that one you were working upon when it all happened. Nevertheless, it is something. It is also advisable to scan your PC for viruses with the anti-malware utility after the OS is rolled back.
There are other ransomware products, besides Japan, that work similarly. Examples of those are Jhdd, Hhjk, Xcvf, and some others. The two major differences between them and the Japan are the ransom amount and the method of encryption. The rest is almost identical: files become blocked, their extensions altered, ransom notes appear in each directory containing encrypted files.
Some fortunate people were able to decrypt the arrested files with the aid of the free tools provided by anti-malware developers. Sometimes the racketeers accidentally send the decoding code to the wronged in the ransom readme. Such an epic fail allows the user to restore the files. But naturally, one should never expect such a chance. Make no mistake, ransomware is a tamperers’ instrument to pull the money out of their victims.
How to avert ransomware infiltration?
Japan ransomware has no superpower, neither does any similar malware.
You can armour your PC from ransomware injection within three easy steps:
- Never open any letters from unknown mailboxes with strange addresses, or with content that has likely no connection to something you are waiting for (can you win in a money prize draw without participating in it?). In case the email subject is more or less something you are waiting for, check all elements of the suspicious letter carefully. A fake email will surely have mistakes.
- Never use cracked or unknown software. Trojans are often spreaded as an element of cracked products, most likely under the guise of “patch” preventing the license check. But untrusted programs are difficult to distinguish from reliable software, as trojans may also have the functionality you seek. You can try searching for information on this software product on the anti-malware forums, but the best solution is not to use such programs at all.

FAQ
🤔 How can I open “.japan” files?Is it possible to open“.japan” files?
Unfortunately, no. You need to decipher the “.japan” files first. Then you will be able to open them.
🤔 I really need to decrypt those “.japan” files ASAP. How can I do that?
Hopefully, you have made a copy of those important files. In case you haven’t, there is still a chance that you do have a Restore Point from some time ago to roll back the whole system to the moment when it had no virus yet, but already had your files. All other solutions require time.
🤔 What should I do if the Japan virus has blocked my PC and I can’t get the activation code.
🤔 What could help the situation right now?
Some of the blocked data can be found elsewhere.
- If you sent or received your important files by email, you could still download them from your online mailbox.
- You might have shared photographs or videos with your friends or relatives. Just ask them to give those pictures back to you.
- If you have initially got any of your files from the Web, you can try doing it again.
- Your messengers, social networks pages, and cloud storage might have all those files as well.
- Maybe you still have the needed files on your old computer, a notebook, mobile, memory stick, etc.
USEFUL TIP: You can employ file recovery programs5 to get your lost data back since ransomware blocks the copies of your files, deleting the original ones. In the video below, you can learn how to recover your files with PhotoRec, but remember: you can do it only after you kill the virus with an anti-malware program.
Also, you can contact the following governmental fraud and scam sites to report this attack:
- In the United States: On Guard Online;
- In Canada: Canadian Anti-Fraud Centre;
- In the United Kingdom: Action Fraud;
- In Australia: SCAMwatch;
- In New Zealand: Consumer Affairs Scams;
- In France: Agence nationale de la sécurité des systèmes d’information;
- In Germany: Bundesamt für Sicherheit in der Informationstechnik;
- In Ireland: An Garda Síochána;
To report the attack, you can contact local executive boards. For instance, if you live in USA, you can have a talk with FBI Local field office, IC3 or Secret Service.
