Antique Japanese Sword Katana Katana Attributed to Hosho Sadayoshi with NTHK Kanteisho for the blade and NBTHK Hozon for the Koshirae

【Description】

Summary

 This blade is attributed to Yamato Hosho Sadayoshi (大和保昌貞吉) in Gen-O era (1319-1321: Late Kamakura period). Yamato is the name of the province located in today’s Nara prefecture. Hosho is the school that flourished during the late Kamakura-early Muromachi period (early14th-early 15th century).

 Hosho school was founded by Sadamune (定宗) in the early 14th century in Yamato province (Today’s Nara prefecture). The prominent swordsmiths who belonged to this school were Sadayoshi(貞吉), Sadakiyo(貞清), and Sadaoki(貞興). The Hosho school was famous for creating blades with *Masame Hada, one kind of steel surface pattern that appeared on the Japanese sword.

 

 There were five prestigious schools, including Hosho school, during the Kamakura-early Muromachi period in Yamato province. They are called Yamato Goha(大和五派); Senjyuin(千手院), Shikkake (尻懸), Taima(当麻), Hosho(保昌) and Tegai(手掻) 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 back then.

 Monks needed many weapons as there were many political rivalries between influential temples. They required strong weapons like swords to protect themselves. During this time, Hosho school or other Yamato sword schools met the requests from monks. They also forged blades for Samurai during their heyday.

 

Yamato Den

 The swords forged in Yamato regions are famous for their beautiful Jigane, steel surface, and straight tempering line (Suguha). And, they invented the particular sword-forging tradition called YAMATO DEN. This blade has a beautiful Jigane with a Suguha tempering line, which shows an outstanding characteristic of the Yamato sword. The overall condition is excellent. Based on the shape of Nakago(Tang), it was shortened in the past. We assume its original length was much longer than it is now.

 

Masame Hada

 Masame (柾目) means straight grain in Japanese, which is often seen in the work of Hosho school. Masame Hada is the Japanese sword terminology for the Hada (steel surface pattern of the Japanese sword) that looks like straight grain when one cuts a tree in half.And it usually is combined with Itame Hada, another grain pattern that looks like wood-grain seen in the Japanese sword. 

*Please keep in mind that there are a couple of minor Kitae Kizu on the Mune (the backbone of the blade). Please check the listed photos. If you like to see more detailed condition, please feel free to contact us.

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.

 According to its NBTHK certificate, this Fuchi Kashira depicts a scenery of a battle. You would find the figure of fighting Samurai warriors. They are in ships, plowing through the rough waves and advancing valiantly against the enemy. There is a famous theme that has sometimes been seen in sword mountings as a design: the Genpei Kassen (源平合戦). Although we are unsure if this Fuchi Kashira depicts exactly this battle, here we would like to introduce its synopsis as a possibility and share a famous piece of Samurai history with you.

 The Genpei Kassen does not refer to one battle. This is a collective term for the civil wars heated in various parts of the country that continued over six years from 1180 until 1185. It is also called the Jishou Juei-no Ran (治承・寿永の乱). This was the conflict between the Minamoto (源) clan (Genji family) and the Taira (平) clan (Heike family). By the call of Mochihito Ou (以仁王), many Samurai raised armies to overthrow the Taira family. It was the trigger of this protracted conflict. Mochihito Ou was unfortunately beaten by the Taira family and passed away in 1180. However, after that, Minamoto family side Samurai defeated the Taira side armies one after another. Finally, the Minamoto side won the battle and overthrew the Taira clan in 1185 at Dan-no Ura (壇ノ浦). It was the final battle of the Genpei Kassen, which led to the destruction of the Taira clan, who reached the height of glory. 

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

 Fierce tiger is designed on this Menuki. The tiger is a brave animal. A theory says people considered the tiger pattern would protect people from evil spirits. Therefore, its pattern has been treated as a talisman. The tiger design has also been regarded as the symbol of life activity when “tiger” is written by a Japanese Kanji character (漢字, a kind of Japanese letter) based on its meaning. It is said people wished boys’ healthy growth by using the tiger pattern.
   
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. 

 A fish-like animal and waves are designed for this Tsuba. According to the certificate, this fish is a Koi (鯉, domestic carp). Based on an ancient foreign story, many fish tried to climb the waterfall called the Ryumon (竜門, dragon gate) in the rapid stream of the Yellow River. As a result, only Koi climbed up and became a dragon and ran through the sky. This is the reason why “Koi-no Taki Nobori” (鯉の滝昇り, domestic carp climbing waterfall) became a symbol of success in life. The Ryumon legend is associated with this story. By living confidently and making efforts, people hoped for their children to grow up to become magnificent people. Samurai families then might have used this fish motif wishing their sons to be promoted to high-ranked Samurai.

Saya Saya is the scabbard for the Japanese sword.
