Required Features: Two-Factor Authentication, Whois Privacy Protection

The required features are the following two points:

• ✅ Two-factor authentication
• ✅ Whois privacy protection

First, since this is for corporate use, we require “two-factor authentication” as a mandatory security feature.

Regarding Whois privacy protection, many people probably use this service, so it would be difficult for many if this wasn’t available.

Domain Registration and Management Services We Passed On

お名前.com

• ? No two-factor authentication
• ✅ Whois情報公開代行｜ドメイン取るならお名前.com

Since it doesn’t meet our requirements, we passed on this option. Although お名前.com is the cheapest, it’s unfortunate but we prioritize security.

Conversely, if two-factor authentication functionality is added, お名前.com would likely become the top choice.

• .jpドメイン｜ドメイン取るならお名前.com
• .co.jpドメイン｜ドメイン取るならお名前.com

ムームードメイン (MuuMuu Domain)

• ? No two-factor authentication
• ✅ WHOIS情報の変更・確認方法 | ムームードメイン

Since it doesn’t meet our requirements, we passed on this option.

That’s all about wanting to register .jp or .co.jp domains with security focus while keeping costs low from the Gemba.
