Antique Japanese Sword Tachi attributed to Unju with NBTHK  JUYO TOKEN Certificate

【Description】

Summary

 This blade is attributed to Unju (雲重), active during the early-mid Nanbokucho period (1352-1374: Bunna-Oan era), based on his remaining works. He belonged to Unrui (雲類) school, which flourished from the late Kamakura-mid Nanbokucho period. He lived in Ukai (宇甘) village in Bizen province (Today’s Okayama prefecture). He was known as the son of Unji (雲次), another prominent figure in this school. 

The origin of Unrui school

 The founder of Unrui school was Unsho (雲生). According to a legendary story, Unsho was ordered to forge a Tachi blade for the emperor Godaigo (後醍醐天皇), one of the most famous emperors in Japanese history. And, Unsho was having difficulty forging a blade that satisfied him. However, one night he dreamed about floating clouds. And he got an idea from these clouds in his dream to make Hamon, and he successfully created the blade for the emperor. 

 He devoted this Tachi blade to the emperor Godaigo, and the emperor was impressed by the level of Unsho’s craftsmanship, saying, “The activity of Hamon looks like real clouds.” And the emperor Godaigo ordered Unsho to use the letter 雲(Un or Kumo: Clouds in Japanese). Since then, the school was named Unrui (雲類). All the members of the Unrui school used Un(雲) in their maker’s names. Unsho was active during Kengen era (1302-: Late Kamakura period). And the father of Unjyu, Unji, was the son of Unsho. Unrui school is also known as Ukai (宇甘) because they lived in the village in Bizen province.

 It is said that the works of Unrui school resemble that of Rai school in Yamashiro province, Aoe school in Bitchu province, or Yamato Den, depending on the blades. One theory says that the members of Unrui school moved from Yamashiro (Today’s Kyoto) to Bizen Province during the late Kamakura period. Compared to other swordsmiths living in Bizen province, Unrui school was influenced by Yamashiro DEN (One of the five traditions of the Japanese sword-forging). 

Jihada

It has dense Itame Hada (板目肌), and there is plenty of Ji Nie (地沸え). There is a subtle Midare Utsuri.

Hamon

Suguha with Koashi (小足), Sakaashi(逆足), Yo (葉). There is Ko Nie (小沸え) near the Habuchi area. You can see activities of Kinsuji (金筋) and Sunagashi (砂流し).

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 JUYO TOKEN(重要刀剣) 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, exceptionally well preserved and of high quality with artistic value. JUYO is one rank higher than Tokubetsu Hozon. To be eligible for a Juyo Token, it needs to be appraised as a Tokubetsu Hozon Token first. It is extremely rare for an antique Japanese sword to be appraised as JUYO TOKEN, and it is highly desirable among Japanese sword collectors.

NakagoNakago is the tang of the Japanese sword.

 

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).

 All of the sword mountings of this Koshirae are decorated with the common motif: the Gosan-no-Kiri Mon (五三の桐紋). It comes from the Kiri (桐, paulownia) pattern, and the Gosan-no-Kiri Mon is a popular design that this flower pattern is used. The Kiri (桐) pattern is generally composed of three standing straight inflorescences and three leaves. The number of blooming flowers at each inflorescence means the ranks of this design. The imperial family and national leaders of the time once used this plant pattern. Today, this plant pattern is used as the crest of the Japanese Government. And it is permitted to use by ordinary households and is appreciated as their family crests. According to a tradition, the Houou (鳳凰, Fenghuang, a kind of sacred beast) rests its wings at the paulownia tree; therefore, it has come to be regarded as a sacred plant.

 We estimate this pattern is designed here as a family crest. As mentioned above, this was a noble design that was once allowed for limited use by people of high social status. Based on this history, we could infer the possibility that a person with some degree of official rank had ordered this Koshirae.

 The surface of each sword mounting and metal fittings were finished with the Nanako-Ji (魚子地) technique. By hitting with the Nanako-Ji Tagane (魚子地鏨, chisel used for this technique), delicate fish egg-shaped protrusions are made on the surface of the metal. This process is often seen and is one of the elements that add gorgeousness to the appearance of metalworks.

 

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

 In the Tachi Koshirae (太刀拵), these sword mountings are called the Kabutogane (冑金/兜金) and the Fuchi Kanamono (縁金物). The Kabutogane is a metal fitting attached to a handle’s end. And the Fuchi Kanamono is also a metal fitting attached to the handle, but on the opposite side of Kabutogane.

 In addition, 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.


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

 Three family crests are arranged side by side. While we cannot see its entire shape because of the Tsukamaki thread, the common motif is designed to even such a small part. We could also feel the consistent commitment of the client here.

   
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 Tsuba is categorized as the Aoi (葵) Tsuba, and this type of Tsuba is often seen in the Tachi Koshirae. If you focus on the four corners, you will find a heart-mark hole at each corner. On this Tsuba, you could find eight heart marks in total on each side. This design is the Inome (猪の目, boar’s eyes) pattern. It has been used since ancient times. Some people believed the Inome pattern would bring good luck and protect people from evil spirits or fire.

 The Gosan-no-Kiri Mons are arranged evenly and create a symmetrical design. The Mimi (耳, edge) part is framed with a thick golden plate, and it makes a brilliant appearance of this Tsuba.


Saya Saya is the scabbard for the Japanese sword.  

 You could find the same Gosan-no-Kiri Mon on this scabbard. The Asi Kanamono (足金物, metal fittings attached to the scabbard for hanging the Obitori), the Seme Kanamono (責金物, a metal fitting attached to the middle of the scabbard to protect the scabbard), and the Ishiduki Kanamono (石突金物, a metal fitting attached to the end of the scabbard), these metal parts are also decorated with this plant design. In addition to the wonderful value of the blade itself, we would like you also to enjoy viewing this Koshirae’s high decorativeness and good condition.

Authentication PaperNBTHK JUYO TOKEN Certificate for the blade (No. 9585)

  NBTHK, also known as Nihon Bijutsu Touken Hozon Kyokai (the Society for the Preservation of the Japan Art Sword), is one of the oldest Japanese sword appraising organizations in modern-day Japan.
