WHOIS 记录

The .CO.JP domain extension is Japan's corporate second-level domain managed by JPRS (Japan Registry Services). Registration is strictly limited to companies incorporated under Japanese law, with a unique restriction: each corporation may register only one .co.jp domain. This one-domain-per-entity policy makes .co.jp one of the most exclusive and trusted commercial extensions globally. Widely regarded in the East Asian market as the highest-trust domain for legitimate Japanese businesses. It requires a minimum label length of 2 characters and supports up to 63 characters. It does not support IDN characters, meaning only standard English characters are allowed. Registration is completely open and unrestricted globally to individuals and organizations.
