Antique Japanese Sword Tanto Attributed to Yamamura with NBTHK Tokubestsu Hozon Certificate
This blade is attributed to Yamamura (山村) school, which flourished during the late Nanbokucho period (Late 14th century) in Echigo province (Today’s Niigata prefecture). The school was founded by Yamamura Masanobu (正信), who originally belonged to Nobukuni school in Yamashiro province (Today’s Kyoto prefecture). It is said that Yamamura Masanobu was a feudal lord in Echigo province and learned sword-forging techniques from the second-gen Nobukuni by inviting him from Yamashiro province. Nobukuni school had several branches and Yamamura school is known as Yamamura Nobukuni, one of the most prominent branches.
About Yamashiro Province
Yamashiro province was famous for its sword-making style called YAMASHIRO-DEN. YAMASHIRO-DEN’s origin dates back to the Heian period (794 A.D) when the capital city was moved from Nara to Kyoto. The swordsmiths in Yamashiro province initially prospered by forging swords for court nobles and imperial families. Later on, they also forged swords for feudal lords after Samurai military government took control of Japan. There are so many renowned swordsmiths from this region. It is said that the founder of YAMASHIRO-DEN was Sanjo Munechika. And there are four prestigious main branches in this region. They are Sanjo, Rai, Nobukuni, and Awataguchi. One of the most characteristics of YAMASHIRO-DEN is its elegant design and beautiful Jigane. You can see beautiful Jigane (steel surface) from this Tanto. It is said that the charateristics of Yamamura scool was very close to that of Nobukuni school.
What is Tanto?
It was initially used as a supplemental weapon for Samurai on horseback, who used a pole weapon or long sword in the Kamaura-Muromachi period. Samurai aimed at an unprotected area of his enemy’s armor with Tanto while having to fight with close distance.
TANTO was named accordingly, depending on how you carry it, such as HUTOKORO-GATANA (懐刀; Stomach-Sword) or KOSHI-GATANA(腰刀; Waist-Sword) or elsewise. TANTO was also a gift for a bride from her family in a traditional Japanese wedding, as it is believed that TANTO would be divine protection from evil power.
This blade 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 is one relatively noticeable Kitae Kizu on the Mune (backbone of the blade). If you like to know the detailed condition, please feel free to contact us.
Cutting Edge Length(Nagasa)：28.2 cm ( 11.1 inches)
Curvature(Sori)：0 cm (0 inches)
The crystalline structure which forms along the cutting edge of a blade as a result of the hardening process
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.
You would find a figure of an animal swimming in the sea is engraved on each Fuchi and Kashira part. It is probably a turtle, but the shape of its head and other features are slightly different from commonly seen turtles. We estimate it is Genbu (玄武), who is a god in the continent and deification of the stars of the north. Genbu is a member of Shijin (四神, four gods) with Seiryu (青龍), Byakko (白虎), and Suzaku (朱雀). Each of these spiritual beasts protects the four directions: north, east, west, and south. Genbu has long been said to be a god that has the power to ward off evil spirits, ward off evil spirits, and ward off epidemics. In addition, since this spirit animal symbolizes the underworld (life) and water, which are the elements that are directly connected to human life, it is said that among the folk, Genbu was the most popular of the four gods, and folk religion was popular.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
Seeing from the gaps of the Tsukamaki thread, we could find a figure of a man. Due to wear and tear over time and use, we are unsure the details of what the original design was. However, we assume it was probably modeled after a certain person (such as a great historical figure or a character from a famous story).
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.
If you focus on the center part of this Tsuba, there is an engraved inscription. It is written as follows: 埋忠 (Umetada). The first Umetada: Umetada Myouju (埋忠 明寿), was born in Yamashiro-no Kuni (山城国, today’s Kyoto prefecture) as the Shigetaka (重隆) ‘s second son. The Umetada family was a distinguished family who produced excellent swordsmiths, and Myouju succeeded to the household headship. He firstly served under Ashikaga Yoshiaki (足利義昭, 1537-1597, the 15th Shogun of the Muromachi Shogunate), and later his works were admired by famous Samurai such as Oda Nobunaga (織田信長, 1534-1582), Toyotomi Hideyoshi (豊臣秀吉, 1537-1598), and Tokugawa Ieyasu (徳川家康, 1543-1616).
The Umetada family was a prestigious school of metalworks in Kyoto. They produced both Japanese swords and sword mountings. This school was involved in a wide range of areas related to Japanese swords, such as remaking famous old swords, inlaying gold inlays with the name of the sword maker, making metal fittings, and recording famous swords. It is thought that the entire studio was engaged in these various tasks. Please note that there is NO provenance or certificate that proves its signature’s authenticity.
Kozuka：Kozuka is a small knife stored in Kozuka Hitsu(groove of the sheath of the Japanese sword).
A Kogatana (小刀, small knife) is stored in the Kozuka. The surface of this Kozuka is decorated with the Nanako-Ji (魚子地) technique. This process makes a uniform minimal protrusions pattern by hitting the Nanako-Ji Tagane (魚子地鏨, a chisel for this technique) on a metal surface. This decorative technique is often seen on sword mountings. About the design, we believe its theme is the Ukai (鵜飼い). It is a fishing method in which cormorants are skillfully manipulated to catch fish in the river.
Saya： Saya is the scabbard for the Japanese sword.
Authentication Paper：NBTHK Tokubetsu Hozon Certificate for the blade (No. 1017645)
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.
