Buy a .co.jp domain: everything you need to know

You've come to the right place. This page covers everything worth knowing about purchasing a .co.jp domain — why it might be the right fit, what the process looks like, and how Site.eu keeps things simple and affordable. Whether you're registering a new domain or moving an existing one over, we offer a smooth experience from start to finish.

Why buy a .co.jp domain?

The .co.jp extension is Japan's country-code top-level domain (ccTLD), and it carries real meaning for businesses operating in or targeting the Japanese market. For Japanese consumers, seeing a .co.jp address tends to signal that a business is locally grounded and legitimate — something that genuinely matters in a market where trust plays a significant role in purchasing decisions.

There's also a practical SEO benefit. Search engines generally favour locally relevant domain extensions when serving results to users in a specific region, so a .co.jp domain can improve your visibility in Japanese search rankings compared to a generic alternative.

Industries like e-commerce, finance, technology, tourism, and retail are natural fits. So are international businesses setting up a Japanese subsidiary, or entrepreneurs launching products and services aimed specifically at Japanese audiences. In these cases, a .co.jp domain isn't just a nice-to-have — it's often a foundational part of building a professional local identity.

Key features of the .co.jp domain extension

The .co.jp extension gives registrants solid control over how their domain is configured. You can update DNS records, modify nameservers, and change domain holder information as needed. Domain lock is also supported, which helps protect against unauthorized transfers or changes — a useful layer of security for any domain you rely on.

Technical specifications and limitations

A few technical points are worth keeping in mind. Domain names must be between 3 and 63 characters in length. The .co.jp extension does not support Internationalized Domain Names (IDN), meaning registrations are limited to standard ASCII characters. If you were considering a domain name using non-Latin scripts or special characters, this is an important limitation to be aware of before proceeding.
