Description
This katana has no kantē-sho (authentication certificate), so the information of tang/shirasaya cannot be guaranteed. That said, the description of the written details is as follows:
Inscription Referring to Nagamitsu – A Renowned Swordsmith of the Osafune School
This katana has no signature (mei) on the tang (nakago). However, the shirasaya (plain wooden scabbard) bears an inscription that attributes the blade to “Bizen Osafune Nagamitsu.”
Nagamitsu is known as a prominent swordsmith of the Bizen Osafune School during the Kamakura period. The inscription suggests an association with his name, but this is not an official attribution and should be regarded only as a reference.
Inscription Possibly Attributed to Kunzan Sensei
The shirasaya inscription includes what appears to be the name of Kunzan Sensei, a respected sword scholar. However, it is not possible to verify whether the inscription was written by Kunzan Sensei himself.
The content of the inscription describes the blade as having refined steel and a skillfully crafted hamon, noting qualities associated with high-level craftsmanship.
Well-Preserved Condition
The blade remains in excellent condition, with no visible rust, chips, or flaws. Despite the absence of a signature, it has been carefully maintained and retains its beauty and character.
The inscriptions on the shirasaya offer an interesting perspective for those interested in Japanese swords, adding a layer of historical curiosity to this piece.
