XServer Domain is a domain registration service from XServer Inc., one of Japan’s most prominent hosting providers. It lets users register and manage a wide range of domains, including .jp, .co.jp, and popular extensions like .com and .net.

A key advantage is clear, honest pricing with no hidden maintenance fees or extra charges: the listed price is the actual cost. As one of the few ICANN-accredited registrars in Japan, the service manages global domains directly, alongside .jp domains through its JPRS designation. Free WHOIS privacy and DNS management come with every registration.

Users who also subscribe to XServer hosting can manage domains and servers from one account, and may receive free domains as part of their hosting plan. Phone support is available on weekdays, with email support around the clock, making it approachable for beginners setting up their first domain.
