Antique Japanese Sword Katana Signed by Naminohira Yasuhiro with Tokubetsu Hozon Certificate 

【Description】

 This blade was signed  by Naminohira Yasuchika(波平安廣), who was active during Kyoho era(1716-1736: Mid- Edo period). He belonged to a prestigious school called Naminohira school. Naminohira is also a place located in the Satsuma domain(today’s Kagoshima prefecture). Yasuhiro was the son of Yasumasa (安正), who was also the prominent figure in Naminohira school. Yasuhiro originally signed Yasutomi (安富) in his early career. 

 Naminohira(波平) was one of the most influential schools in Satsuma domain founded by a Yamato-Den swordsmith Masakuni(正國) during the late-Heian period(Late 12th century). They were known for having their smith name with one of these letters, 行(Yuki) or 安(Yasu).

 The Naminohira swords were cherished among Samurais in the marine army, mainly because the name Naminohira(波平) means “Tides are quiet.” in Japanese.
The origin of the name Naminohira dates back to the school’s foundation. It is said that the founder Masakuni was able to calm the waves by dedicating his sword to the sea when his school from Yamato sailed to live in Satsuma domain. Since then, he began to use the title “Naminohira Yukiyasu (波平行安)” – “Tides are quiet, ’tis an easy way.” From the late-Heian period until the end of Samurai times(Late 19th century), the Naminohira school had kept the mastership for a thousand years.

 Yasuhiro was a swordsmith from the Naminohira school back in the mid-Edo period. He would like to apply the authentic Yamato-Den techniques in his craft. His work appears to have features that derive from Yamato-Den; razor-edge sharpness and exceptional strength.
Satsuma province had many Samurais and smiths back in the day, making it difficult for most smiths to keep their jobs through the era. However, the Naminohira school always remained prominent in the evolving sword industry – and their work is still beloved by Katana fans to date.

 

  It is appraised as a Tokubetsu Hozon Token(特別保存刀剣) 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, especially well preserved and high quality with artistic value.

*Please keep in mind that there are visible black rust right above the Nakago area and some others. If you like to know the detailed condition, please feel free to contact us.  If you don’t mind paying additional cost, we will partially have it polished to enhance its beauty.

【 Blade】
Cutting Edge Length(Nagasa) 69.8 cm (27.5 inches)
Curvature(Sori)1.4 cm (0.55 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



 

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.

 This Fuchi Kashira has a plain design. On the surface, there are areas where the metal has changed in texture over time and areas where it has peeled off. Instead of ornamental decoration such as gold or silver inlays, you could directly see such changes due to aging. We hope you would enjoy them as antique textures.


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

 You would find a figure of the Saru (猿, monkey) on each side of the handle. The upper Menuki’s monkey is running, and he (or she) holds something in his (or her) hand. Another monkey is wearing a golden cloth and brings the Kagura Suzu (神楽鈴). We could also find a child monkey sitting around this monkey. Generally speaking, as we know, monkeys belong to the same primates as us humans. So it is considered to be the closest animal to humans. Probably, it is why monkeys have often been personified in pictures and stories since ancient times. In this Menuki as well, the figures of monkeys are portrayed with the same gestures as humans. The Kagura Suzu is a bell used when dancing Kagura (神楽, sacred Shito dance). Its handle is made by connecting several small bells. It is a tool used by Shinto priests and maidens during Shinto rituals to call the gods or pray to drive out evil spirits. Such a religious idea might have inspired this Menuki’s design.

   
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. 

 Two circle-shaped objects and a tool that seems to be a Biwa (琵琶, pipa) are engraved on this Tsuba. There is no gold or silver coloring, and the shapes of these motifs are carved out using thin line carvings. Regarding the object described as resembling a pipa, since it also looks like a sword, there are various possibilities depending on the person looking at it.

Saya Saya is the scabbard for the Japanese sword.  

Authentication PaperNBTHK TOKUBETSU Hozon Certificate for the blade (No. 1017569)

  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 on March 2nd in the 4th year of Reiwa (2022). They appraised it as Tokubetsu Hozon Touken, the blade especially worth preserving for Japanese society. 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.
