Basically, you should serve the document with Hague compliant method rather than the private serving. You must translate the document as well if you’d like to do it with a formal manner.
Japan is not based on common law. There is no process service system in Japan. Legal documents must be served via post office in Japan by law. There is a good chance that the private service like our service won’t work well for a middle size or bigger company. Their attorney will simply neglect it and invalidate it at the Japanese District Court due to the plaintiff not complying the Hague Convention. In that case, the client has to serve the document with Hague method. So there is a good chance that the client will waste time and money for this.
You should better suggest the client contact a Hague attorney instead of process servers or simply serve it to their local subsidiary company.
We will take on this case only when both parties agree to the private service method where the defendant will never complain to the Japanese court.
Yes. But please be advised that due to the Hague Service Convention (https://en.wikipedia.org/wiki/Hague_Service_Convention), officially you have to translate all the documents and deliver the process through the central authority which is the Ministry of Foreign Affairs in Japan.
If the respondent is evasive, he or she can file a claim to a Japanese local court and revoke the validity of the personal service. In that case, the plaintiff has to do it again based on the Hague Service Convention compliant method.
We have an experience of serving a process from a US court to a person stationed on the US military base in Japan.
But since noone is allowed to enter the US military base without permission, we need to have an appointment with the respondent or their supervisor before visiting there.
In other words, it is not possible to serve a document to the US military base who is evasive to our service.
