Antique Japanese Sword Katana Signed by Kanabo Nobukiyo with NBTHK Hozon Certificate

【Description】

Summary
 This blade was signed by Nobukiyo (延清), who was active during the Late Muromachi period (1532-1555). He belonged to Kanabo (金房) school, according to the NBTHK’s appraisal. Kanabo (金房) school flourished in the late Muromachi-Azuchi Momoyama Period (Mid-Late 16th century). It is said that Kanabo school was founded in the Dai-Ei era (1521-1527: the late Muromachi period) by Kanabo Masanaga, an offspring of a member of Tegai school in Yamato region(today’s Nara prefecture).

 The swordsmiths who belonged to Kanabo school made blades for Sohei, Buddhist warrior monks, and Samurai in the area during the warring state period called SENGOKU JIDAI when there were so many rivalries and civil wars among feudal lords. One of the most renowned swordsmiths in Kanabo school is Kanabo Masatsugu (金房政次). According to Kokin Kaji Biko (古今鍛冶備考), a book about famous Japanese swords written during the Edo period, a spear forged by a member of Kanabo school is listed as one of the three most renowned spears. This spear is called Nihongo (日本号). 

About Tegai school
 There were five prestigious schools, including Tegai, during the Kamakura-Nanbokucho period. They are called Yamato Goha(大和五派); Senjyuin(千手院), Tegai(手掻), Taima(当麻), Hosho(保昌) and Shikkake school. They served politically powerful monks and temples in Nara, such as Todaiji temples. 

 They were initially forging swords for military monks who became powerful due to the government’s policy. Monks needed many weapons as there were many political rivalries between influential temples, and they needed strong weapons like swords to protect themselves. During this time, Tegai school or other Yamato sword schools met the requests from monks. They also forged blades for Samurai hired by those monks during their heyday.

 Tegai school belonged to YAMATO DEN, the longest history among GOKADEN and five Japanese sword forging techniques. The blades forged by swordsmiths residing in Yamato region are generally called Yamato Mono.

 

This blade is appraised as a Hozon Touken (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 and high quality with artistic value. 

*Please keep in mind that there are a few Kitae Kizu on this blade. If you like to see the detailed condition, please feel free to contact us.

【Blade】
Cutting Edge Length (Nagasa): 68.3 cm ( 26.9 inches)
Curvature (Sori): 1.81 cm (0.71 inches) 


 

Hamon
The crystalline structure which forms along the cutting edge of a blade as a result of the hardening process.
Jimon (Jihada):
Visible steel surface pattern created by folding and hammering during forging process.



 

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.

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

 You would find a figure of the dragon in the gaps of the Tsukamaki thread. Although it has partially faded due to aging, we could see the traces that golden paint was applied to these dragons. Initially, the dragon was an imaginary creature found in ancient foreign traditions and myths. Furthermore, it is regarded as a symbolic beast of auspicious signs. Its body is likened to nine animals: antlers are deer, the head is a camel, eyes are demons, the neck is a snake, the belly is the Mizuchi (蛟, a mythical animal in Japan that looks like a snake and has a horn and four legs), scales are fish, claws are falcons, palms are tigers and ears are cows. It was thought that the dragon would reign at the top of all animals because of its odd-looking appearance.

 If you focus on these dragons’ hands, you would find that they bring a ball-shaped object in their hands. This item is the Nyoi Houju (如意宝珠, Cintāmaṇi), a fantasy jewel that fulfills any desire and gives out treasure, clothes, food, and drinks. Moreover, it heals illness and suffering, removes evils, purifies muddy water, and prevents disasters. It is said this magical item is taken from the brain of the dragon king. There are lots of dragon-designed sword mountings. It shows that many Samurai cherished this dignified beast motif.

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 Yotsu-Mokkou (四ツ木瓜) shaped Tsuba is decorated with brass inlay. The rope pattern brass inaly is placed on the edge part of this Tsuba. Due to its appearance, we estimate this Tsuba could be categorized as the Heianjo-style Tsuba. Please note that there is no proof. We would like to propose a possibility here.

 This style of Tsubas was established in Yamashiro (山城, today’s Kyoto Prefecture). According to a theory, this school was born during the reign of the sixth Shogun (将軍, general) of the Muromachi (室町) Shogunate. And its style was influenced by the tastes of the Shogun. The works of this school could be classified into two types according to their noticeable characteristics. The one is the Heanjo Sukashi Tsuba (平安城透鐔), which is generally called the Kyou Sukashi Tsuba (京透鐔). Most Tsubas have circle shapes, and motifs are engraved dynamically with openwork. The refined composition and outstanding techniques give the impression that metalworkers attached importance to the beauty of openwork more than the practicality of a Tsuba itself. Another type is the Heanjo Zougan Tsuba (平安城象嵌鐔), which is also called the Heianjo Shinchu Zougan Tsuba (平安城真鍮象嵌鐔). Shinchu (真鍮) means brass and Zougan (象嵌) means inlay in Japanese. This style inherited Ounin Tsuba’s (応仁鐔) techniques. Motifs such as Botan (牡丹, peony), Nanten (南天, nandina), or Karakusa (唐草, arabesque) patterns are inlaid with brass on circle-shaped iron Tsubas. Later, artisans started using gold, silver, and Shakudou (赤銅, an alloy of copper and gold) to create more ornate Tsuba works.

Saya: Saya is the scabbard for the Japanese sword.  

Authentication Paper: NBTHK Hozon Certificate for the blade 

 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. They authenticated the blade in June, 2023. They appraised it as Hozon Touken, the blade worth preserving for Japanese society. We are expecting to receive its authentication paper during early-mid November. The purchaser will receive this original certificate as well. We can also translate what is written into English and make a PDF file for your record if you request.

 

Registration Number: Aichi 15657

 The Board of Education in Aichi prefecture issued a registration paper for this sword. It is called Jyu Token Rui Torokusho (銃刀剣類登録証). Bunkacho (The Agency for Cultural Affairs) acknowledges a Japanese sword with this paper as a work of art.
