.コム is the new Japanese .COM, signifying a unique Web frontier for users in Japan. Now Japanese trademark owners and website operators can secure fully internationalized domain names and become a part of the burgeoning Japanese Internet network. This TLD, like .COM, can be used for any purpose, and is available to any individual, group, or organization that either lives, works, or is based in Japan, or markets to Japan as part of a global promotion campaign.
There is no specific procedure related to the registration of a domain name.
.コム domain names are allocated on a "first come, first served" basis.
