Features: NBTHK Tokubetsu Kicho Token is attached, but the authenticity of the signature is not guaranteed.
Personally, I believe this is a later-generation Hizen sword.
The Tokubetsu Kicho certificate was issued in Showa 28 (1953), making it quite old, and since the certificate does not include a reference number, it cannot be verified against official records.
