Antique Japanese Sword Katana Signed by Sadayuki with Hozon Certificate
According to NBTHK that authenticated this blade, it was forged by Sadatsugu in the late Muromachi period(450-500 years old). There were more than one swordsmith who signed as Sadatsugu back then and NBTHK doesn’t specify which Sadatsugu forged this blade. Nevertheless, you can see great sword-forging technique from the late Muromachi period.
Based on the characteristic of the blade, we can easily assume this blade was forged in the Bizen domain (today’s Okayama prefecture), which is famous for Bizen Den, one of the five most famous Japanese sword tradition.
When this blade was forged, Japan was in the warring state called Sengoku Jidai where there were so many rivalry and wars between regional feudal lords. The length of this blade is more than 70 cm long and must have been easy for its owner to handle it back then. It would be nice to have a piece that was forged in the warring state period.
This blade has very intricate Hamon (tempering line) and Sadatsugu must have been skilled enough to make such beatiful Hamon on this blade. The entire width is relatively narrow from the bottom to the tip, which makes this blade look elegant.
This blade is appraised as a Hozon Token(保存刀剣) issued by NBTHK(Nihon Bijutsu Touken Hozon Kyokai:日本美術刀剣保存協会). This authentication paper was only given to authentic Japanese swords, well preserved with artistic value.
Please keep in mind that there are a couple of Kitae Kizu on the blade as well as tiny black rust spots. If you like to know the detailed condition, please feel free to contact us.

Nakago：Nakago is the tang of the Japanese sword.
Japanese swordsmiths left the black rust on the tang because it prevents red rust while the tang is in its handle. And the discoloration of the tang was created over time, and it is a great indicator for a Japanese sword specialist to estimate when the sword was forged.
Koshirae: Koshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya(Scabbard), Tsuka(Handle), Tsuba(Handguard).
Fuchi-Kashira：A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.
A type of arabesque pattern is designed on this Fuchi part and is inlaid with golden paint (probably gold or brass). It is a design in which stems and leaves of vines are twined and make curves. As ivy has a strong vitality and grows up without interruption, people regarded this design as a symbol of prosperity and longevity. In Japanese, the vine is called Tsuru (蔓), and it has another pronunciation; “Man.” There is a word 万 (it is also read Man), which means thousand. In the arabesque pattern, leaves and vines are connected like Obi (帯, belt). The word “帯” can also be read “Tai.” Due to its pronunciation, the term “代 (Tai)” is associated. From this word-association game, an idiom 万代 is associated, and it means a thousand generations. In other words, we could imagine that people used this design wishing prosperity and longevity for their clans for a long time.
At the Kashira part, a cloud pattern might be designed, and the gold paint is applied to it, the same as the Fuchi part.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
It is challenging to judge the motif of this Menuki by seeing the gaps from the Tsukamaki thread. We could say that it seems golden paint was initially applied to it. Although some coloring has already flaked off due to aging, we hope you will enjoy it as a part of an antique texture.
Tsuba and Habaki：Tsuba is the handguard for the Japanese Sword and Habaki is the equipment to make the blade not touch its scabbard inside. It prevents the blade from getting rusty and chipped.
This antique Tsuba is decorated with a variety of geometric patterns. Straight lines and curves are finely combined so that it seems as if each pattern is arranged to fill the gaps.
On one side of this Tsuba, you would find the same circle-shaped patterns are designed. It might be treated as a family crest in this work. This mark is categorized as the Hachisuka-Manji (蜂須賀卍) or Maru-ni Manji Mon (丸に卍文). The Manji motif itself is one of the patterns brought to Japan with the introduction of Buddhism. A theory says it is initially related to Hinduism. This design represents luck, and it also it has been used as an emblem of temples.
Please let us introduce to you a Samurai who used this crest: Hachisuka Koroku (蜂須賀 小六, his real name is Masakatsu), who was one of Toyotomi Hideyoshi’s oldest vassals. The Hachisuka family was a feudal lord based in the Hachisuka District in Owari Province (尾張, today’s western part of Aichi prefecture). Koroku also temporally served under famous Samurais such as Saito Dozan or Oda Nobutaka. In any case, Koroku decided on Hideyoshi as the lord of his life. And he remained loyal to Hideyoshi until his death. Many other Samurai families used the Manji pattern for their family crests; it shows how popular this design was among Samurais.
Saya： Saya is the scabbard for the Japanese sword.
