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

Onamae.com supports DNSSEC via a paid add-on called “Secure DNS (DNSSEC)” which is available for a limited set of domain types, including .jp, .co.jp, .com, .net, .tokyo, and .kyoto. Users must enable this service separately for each domain, at an additional cost. Once enabled, DNSSEC is automatically configured, including key management and DS record submission. DNSSEC is not available for all TLDs and cannot be used with third-party DNS services. The service is suitable only for users managing DNS entirely within the Onamae platform.

Onamae.com provides a paid email service called Onamae Mail, which allows users to create domain-based email addresses. It includes webmail access, spam filtering, and support for standard email protocols (POP3, IMAP, SMTP). While the plan allows for unlimited email addresses, the storage capacity is limited (e.g., 10 GB per domain under standard plans), and pricing varies based on the plan and number of domains. This service is intended for users comfortable managing everything in Japanese.
