Onamae.com is one of Japan’s most well-established domain registrars, offering a wide range of domain extensions along with additional services like DNS management, SSL certificates, and shared web hosting. Operated by the GMO Internet Group, it caters primarily to a domestic audience and provides its services exclusively in Japanese.

Onamae.com supports DNSSEC through a paid option, which must be activated for each domain. Once enabled, DNSSEC can be configured for supported TLDs such as .jp, .co.jp, .com, .net, .tokyo, and .kyoto. Onamae handles key management and DS record submission automatically. Domains without this option remain unsigned, and DNSSEC is not available for all domain types or for use with external DNS providers. This makes DNSSEC viable for users who stay fully within the Onamae ecosystem.

Onamae.com offers a paid email service called Onamae Mail, which lets users create unlimited email addresses using their own domain. The service includes webmail access, spam filtering, and supports standard protocols like POP3, IMAP, and SMTP, making it compatible with most email clients.
