XServer Domain is the domain registration service operated by XServer, one of Japan’s largest hosting providers. It offers .jp domains as well as a wide variety of generic and country-code TLDs.

The interface is entirely in Japanese and designed for simplicity, with strong integration into XServer’s hosting and email services. Domain registration comes with free DNS management, WHOIS proxy service, and optional email hosting.

XServer Domain is a solid choice for users comfortable with Japanese who want a unified experience across domain and hosting services within the same provider.

Xdomain provides email functionality bundled with its domain service, allowing users to create custom domain-based addresses via webmail and set up forwarding. Basic POP3 and IMAP support is also available through their hosting platform.
