Antique Japanese Sword Tanto Signed by Korekazu with Hozon Certificate 

【Description】

Summary
 This blade was signed  by Korekazu in the 5th year of the Ka-Ei era (1851). He is also known as the seventh-gen Ishido Korekazu(七代石堂是一), who was the most famous one among other generations of Korekazu.

 The first-gen Korekazu was originally from Omi Koku(Today’s Shiga prefecture). It is said that he was a descendant of Ichimonji Sukemune(一文字助宗) from Bizen Koku(Today’s Okayama prefecture). He moved to Edo and founded Edo Ishido school at the beginning of the Edo period.
This school flourished during the whole Edo period and became one of the most popular ones in Edo city, Musashi Koku. Ishido Korekazu became an Okakaekaji for the Edo government in 1721, exclusively forging swords for the Tokugawa clan. In total, the smith name “Korekazu” lasted 8th generations.

 The seventh-gen Korekazu, who was active at the end of the Edo period, is especially highly regarded among Japanese sword experts because of his superb craftsmanship. The 7th-gen Korekazu is also known as Unjyu Korekazu. The seventh gen Korekazu’s real name is Masataro, and he was born in 1820 and learned the sword-forging technique from his uncle Kato Cho Unsai Tsuna Toshi, who lived in Dewano Kuni(Today’s Yamagata prefecture).Later on, he became a son-in-law of 6th-gen Ishido Korekazu and eventually took over Edo Ishido school. Seventh-gen Korekazu forged swords up until the early Meiji period. He died at the age of 75 in the 24th year of the Meiji era.

 The 7th-gen Korekazu was ordered to forge a sword for Ise Shrine in Mie prefecture and Toshogu Shrine in Tochigi prefecture.
And he was allowed to inscribe the Tokugawa family emblem on these swords. Furthermore, in 1854, he was ordered to forge a sword for sending to the USA and created Naginata for the UK, which was gifts from Japan for diplomatic relations. This fact indicates that Korekazu was one of the Edo government’s trusted swordsmiths and played an essential role at the end of the Edo period.

 The 7th-gen Korekazu was a great master as well because he trained quite a few renowned swordsmiths, such as Katsumura Norikatsu. His sword style is called Bizen-Den, and he was great at forging blades with Choji Midare Hamon, which makes Bizen DEN special.

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 Hozon Token(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.

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), Kozuka.

 

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

*Please keep in mind that there is small damage on the Fuchi.

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

 The figure of a fish is the motif of this Menuki. We propose its model is a Koi (鯉, domestic carp) and Tai (鯛, sea bream). A fish advancing while being caught in a strong current is designed. Although most of the coloring has already faded due to aging, it seems gold and silver paintings were initially applied to each carp and wave.

 According to an ancient foreign story, many fishes 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 could have climbed up and become a dragon and run 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. This fish has been treated as the symbol of success in business and good health. 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. The custom of decorating Koi-Nobori (鯉のぼり, domestic carp streamers) on Tango no Sekku (端午の節句, the Boy’s Festival) is said to have started in the middle of the Edo period. It is one of the traditional customs that has been passed down to the present day.

 Sea bream is a good-luck bringer, so it has often been used for celebrations. Also, this fish is a symbol of the Ebisu (恵比寿) God, who is a member of the Shichifukujin (七福神, the Seven Gods of Good Fortune). The Ebisu God usually has a fishing pole and a sea bream, so initially, he was the God of fishing. Ports will be done well by the comings and goings of ships. Safe voyages will bring profitable businesses; therefore, the Ebisu became famous as the God of trade. In addition, it is believed to be the God of good match or wealth in some areas. Although the Ebisu God himself is not depicted for this Menuki, it might suggest this God’s existence.

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 seems to be made from brass due to its color. There is a semicircular recess, which is intentionally shaped to store a Kozuka. This Tsuba does not have any decoration, such as gold or silvery inlay. However, there are minor dents and rusts; these are an antique texture that shows us its long history.

KozukaKozuka is a small knife stored in Kozuka Hitsu(groove of the sheath of the Japanese sword).

*Please keep in mind Hosaki (blade for the Kozuka Hitsu) is just a metal plate, not the real blade.

Saya Saya is the scabbard for the Japanese sword.  

Authentication PaperNBTHK Hozon Certificate for the blade (No. 321559)

  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 August 3rd in the first year of Heisei (1989). They appraised it as Tokubetsu Hozon Touken, the blade 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.
