Until now, dot coms have always been in the characters of the western Roman alphabet.
But a company in the US will allow Japanese companies to register their names using their own language.
For ".com," this will be replaced by the circular full-stop sign used in Japanese and the "kanji" for company, or "kaisha", according to the company.
It aims to obtain 100,000 new Japanese domain name registrations by the end of this year.
The new service will make internet access easier, for "young children and senior citizens, who up until now have not been able to access the internet due to a lack of proficiency in English," the company i-DNS.net International claim.
It will also free up domain registration capacity by allowing for the use of other languages.
The Californian firm says Japanese is one of 55 non-English languages that its technology supports for domain name registration.
Korean, Chinese, Spanish, German, Arabic, Thai, Tamil, Hebrew and Yiddish are among the 55 compatible languages, claims i-DNS.net.
