Antique Japanese Sword Katana Signed by Hizenkoku Hirouji with Hozon Certificate 


This blade was forged by Hizenkoku Hirouji(肥前国広氏) during the early-mid Edo period according to NBTHK, who appraised this blade. The age isn’t mentioned in the certificate, but we called NBTHK to headquarter to confirm this information.

Hizenkoku, located in Saga prefecture, is the name of the place where Hirouji forged this blade. There were so many renowned swordsmiths who resided in this province. It is said that the reputation of Hizen province started to spread from the beginning of the Edo period when Tadayoshi(忠吉) founded the school there.
Tadayoshi is known as one of the greatest swordsmiths in the early Edo period in Japanese sword history. We believe Hirouji isn’t a direct descendant of Tadayoshi, but this blade has many features of swords forged in Hizeon province.

The swordsmiths in the Hizen province worked under the auspices of the Nabeshima clan, a powerful feudal line in Kyushu island. They were able to produce beautiful Jigane-patterned(Nashijihada) blades, also known as Hizen To, using and mixing carbon steel made in western countries.
Hizenkoku had been flourishing by international trading. That means the geographic location of this domain made it possible to have easy access to western carbon steel.

We are confident you will appreciate Hirouji’s craftsmanship by observing this blade. It also accompanies by gorgeous sword mounting.

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.

It is accompanies by beautiful sword mountings, which were appraised as Tokubetsu Kicho Kodogu. It would be nice to have a Japanese sword whose blade and sword mounting were both appraised by NBTHK.

NakagoNakago 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-KashiraA pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.

This Fuchi Kashira has an uneven surface which is similar to the texture of stones. Therefore, it looks sturdy and makes us feel it will protect the handle from damage. Also, the silvery metal frames this Fuchi Kashira. This edging makes this sword’s handle more decorative and enhances its defensiveness. This Fuchi Kashira might not be looked gorgeous; however, we would like to consider that its design and texture were convenient in battles. 

Tsuka and MenukiTsuka is the handle of the Japanese sword and Menuki is its decoration.
According to its certificate, this Menuki’s motif is Sasagani Zu (笹蟹図). It is a combination of bamboo grass and crab. The word Sasagani (笹蟹/細蟹) was an old name of a spider or spider’s thread. As spiders handle threads skillfully, it is reminiscent of weaving. And it was associated with Orihime (織姫). She is a character in the story of Tanabata (七夕, the Star Festival). A theory says she lived by weaving. That is, Sasagani Zu represents the Star Festival.

This is one of the series of word association games. People loved this type of Hanjimono (判じ物, rebus) during the Edo period. It is solving the riddle that guesses hidden meaning in letters and paintings. This game is challenging to understand without some knowledge and culture. People of the Edo period enjoyed the design itself and enjoyed it by combining it with other elements. From this type of design, we could get a glimpse of a sense of fun in those days. Such a taste influenced Samurai families’ women costumes since the middle of the Edo period. 
Tsuba and HabakiTsuba 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 made from iron and has two large holes. The inside of these holes is framed with silvery metal. It is the same type of decoration as the Fuchi Kashira. Like that part, this Tsuba also does not have gorgeous ornamental designs such as gold inlay. But you would enjoy the texture of iron itself and the beauty of the unity of this sword’s entire Koshirae. 

Saya Saya is the scabbard for the Japanese sword.
