Antique Japanese Sword Katana  attributed to Kunihiro with Hozon Certificate 

【Description】

 This blade is attributed to Hizen Kunihiro (肥前国広). Hizen is the province located in today’s Saga prefecture.  He resided in this province in his career. Kunihiro was especially active during the Kanei- Manji era (1624-1661-:Early Edo Period). Kunihiro’s birthname was Hashimoto Rokurozaemon. He was born as the first son of Hirosada, a renowned swordsmith in the same province. Hirosada was a younger brother of the first-gen Tadayoshi, one of the most famous swordsmiths during the early Edo period. 

 According to the book (Kaihou Kenjyaku) published by Yamada Asaemon in the late Edo period, a blade forged by Kunihiro was ranked as Wazamono (good sharpness). Asaemon was hired by the Edo government as an expert on Tameshigiri or testing cutting. And in this book, he judged how sharp Japanese swords forged by prestigious swordsmiths were. 

 The swordsmiths in the Hizen province worked under the auspices of the Nabeshima clan. They could produce beautiful blades with Konuka Hada, whose steel surface is very smooth. This Hada is one of the most well-known characteristics of the blades produced in Hizen province. The swordsmiths also used and mixed carbon steel made in western countries. Since Hizenkoku flourished through international trading, it had easy access to western carbon steel.

The first-gen Tadayoshi (His uncle)

 The first-gen Tadayoshi was born and raised in the Saga domain. In 1596, under the domain’s order, he went to Kyoto to learn the sword-forging technique from Umetada Myojyu(埋忠明寿), one of the greatest swordsmiths in the early Edo period. He improved his craftsmanship and returned to the Saga domain two years later (1598). The first head of the Nabeshima clan, Nabeshima Katsushige, appreciated the work of the first-gen Tadayoshi very much. Then, Katsushige appointed him as his Okakaekaji, a swordsmith who exclusively forged swords for a specific domain or clan. And Tadayoshi started to stay near Saga castle, the Nabeshima clan’s headquarters. And he founded Hizen Tadayoshi school, which trained more than 100 swordsmiths during the Edo period. Kunihiro is one of them.

Tachi Koshirae 

 This blade is stored in Tachi(太刀) Koshirae. Tachi was mainly used by an armored Samurai with one hand on horseback from the Heian period (794-1185 A.D.) until the early Muromachi period. TACHI was suspended loosely on the left waist with its edge facing the ground so that you could draw it faster to cut down soldiers on the ground.
Because of its gorgeous looking, having a Tachi-style sword mounting became a social status among Samurai. 

 

 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.

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.

 The Kabutogane (冑金/兜金) is a metal fitting that is attached to the end of a handle. And a Sarute/Sarude (猿手) is attached to this Kabutogane. The user of a sword passed the Udenukio (腕貫緒, a cord wrapped around the wrist to prevent a sword from falling out of the hand, mainly used when riding a horse) through this ring. In addition, the Fuchi Kanamono (縁金物) is also a metal fitting attached to the handle, but on the opposite side of Kabutogane.

 It seems all these metal parts of this handle initially had black color on each surface with golden borders. However, some colorings have faded due to aging, and now several parts, especially the Fuchi Kanamono show copper’s brown color. About the design, cherry blossoms are engraved on the Kabutogane and Fuchi Kanamono. It is the same motif as the Tsuba and Ishiduki Kanamono (石突金物, a metal fitting that is attached to the end of the scabbard). Cherry blossom is one of the seasonal things of spring, and it has been loved for a long time in Japan. A theory says that the god of grain exists in cherry blossoms. Therefore, this flower pattern has been treated as the symbol of a plentiful harvest.

Tsuka and MenukiTsuka is the handle of the Japanese sword and Menuki is its decoration.

 We believe the center part of this Menuki; circle-shaped motif is designed here as a family crest. We would say this crest is one of the most well-known family crests: the Aoi-Domoe / Mitsuba-Aoi-no Mon (葵巴/三つ葉葵の紋 ).

 It is a plant pattern in which each stem branches and has characteristic heart-shaped leaves. And today, it is known as the family crest of the Tokugawa Shogunate family led by Tokugawa Ieyasu (徳川 家康, 1543-1616), a famous military commander of the Warring States period. This plant pattern has also been used for the crest of the Kamo shrine in Kyoto prefecture. As mentioned above, the famous Shogunate family, the Tokugawa family, had their family crest with three leaves of Aoi due to their relationship with the Kamo shrine. As its leaves have a habit of always facing the sun, and the word “Aoi” is taken as “Aogu (仰ぐ, looking up)” for the sun, people thought the Aoi pattern would bring good fortune.
   
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 is a typical shape of Tachi Goshirae Tsuba (太刀拵鐔). The difference between Tachi Tsuba (太刀鐔) and Katana Tsuba (刀鐔) is that the top and bottom positions of the Nakago hole (茎櫃, center hole) are reversed. The Tsuba of this Koshirae has Aoi (葵) Tsuba shape.

 If you focus on four corners, you will find a heart mark-shaped hole is engraved on each edge. It is called the Inome (猪の目) pattern. The Inome pattern has been used since ancient times. As its name implies, the boar’s eyes are the origin of this pattern. Some people believed the Inome design would work as an amulet to protect them from evil spirits or fire. Also, it is said it would bring good luck. About the engraved design, it might be a little challenging to see because of its metal color, but you would see the same cherry blossom patterns with the metal fittings of the handle.

Saya Saya is the scabbard for the Japanese sword.
