Antique Japanese Sword Katana Signed by Kunishige with NBTHK Hozon Certificate


This blade was forged by Bitchu Koku Mizuta Jyu Kunishige(備中国水田住国重).
Kunishige belonged to Bitchu Koku Mizuta school, which had been founded by the descendants of Ko AOE Tametsugu(古青江為次) in the late Muromachi period(1530-).

Tametsugu is one of the most famous swordsmiths in the late Heian period-early Kamakura period(Late 12C-Early 13C). One of his works is designated as a national treasure of Japan.
AOE(青江) is the name of the school Tametsugu belonged, and it was located in Kurashiki city, Okayama prefecture today. AOE school was prosperous during the Kamakura-Nanbokucho era(-Late 12C-Late 14C), but it almost disappeared in the Muromachi period. However, because of the descendants of Tametsugu, the Ko AOE-style sword became popular again revitalized the school by changing its name to Botchu Koku Mizuta school.

The Bitchu koku Mizuta school flourished from 1530-1700(The end of the Sengoku period to the mid-Edo period). There were about 60 swordsmiths who signed as Kunishige from this school. During the Edo period, many Kunishige swordsmiths moved to other parts of Japan.

There are two major groups in Kunishige swordsmiths during the Edo period. One is called Oyogo Kunishige school(大与五国重派), lead by Master Otsuki(大月)and the other is called Kono school(河野派) lead by Tameie(為家).

This blade has Kanji inscription on both sides, and they are likely to be Bonji(梵字: Sanscrit letters).

This sword has a Hozon certificate issued by NBTHK. This authentication paper was only given to Japanese swords, worth preserving by Nihon Bijutsu Touken Hozon Kyokai(the Society for the Preservation of the Japan Art Sword). The blade also comes with a beautiful set of Katana style Koshirae.

NakagoNakago is the tang of the Japanese sword.

Japanese swordsmiths left the black rust on the tang on purpose to prevent red rust while the tang is in its handle. And the discoloration of the tang was created over time, which is a great indicator for a Japanese sword specialist to estimate when the sword was forged.

【Other Details】

Koshirae: Koshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya(Sabbard), Tsuka(Handle), Tsuba(Handguard).


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

 The Kagome (籠目) pattern is designed for this Fuchi Kashira. As a design, Kagome means a mesh of baskets made from bamboo or a continuous grid of braid. It looks like a group of hexagram shapes. Each pattern is composed of a star-shaped figure of equilateral triangles. Some people believed this motif had the power to exorcise evil spirits; therefore, the Kagome pattern has been used as a talisman. Since ancient times in Japan, people have considered that evil spirits and monsters do not like being gazed at by eyes. As the Kagome pattern gaps are regarded as “eyes,” people once thought of this design’s sacred power. Also, some families used the Kagome pattern for their family crests. 

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

 The Karajishi (唐獅子) is the motif of this Menuki. The golden metal is applied to it. The Shishi (獅子) means a lion in Japanese, and Kara-Jishi is a lion brought from China to Japan in the Toh period (唐, Tang dynasty, 618-907). The Kara-Jishi typically has curly hair for its head, neck, body, and the tale. In Buddhism, Kara-Jishi is regarded as a symbol of wisdom, and Monju Bosatu (文殊菩薩, Manjushri Bodhisattva) rides lions. According to a theory, Kara-Jishi originates from Komainu (狛犬, stone guardian dogs that exorcize evil spirits).

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. 

 Antique iron Tsuba that has Kozuka and Kougai holes. The Ume (梅, Japanese apricot blossom) is designed for this Tsuba. Some of the Ume flowers have already bloomed, and twigs have several buds. This Tsuba’s irregular-shaped outline might express the shape of a branch of this flower. Japanese apricot blossoms begin to bloom in winter that snow covers its tree. So, this flower tells the arrival of spring. It has been appreciated for a long time ago in Japan. People enjoy its adorable petal shape and scent, gracefully branched tree, and compose many poems. As it comes out in the cold season, it symbolizes the power of perseverance and vitality.

SayaSaya is the scabbard for the Japanese sword.
