Antique Japanese Sword Katana Signed by Jyokeishi Masa-Aki with NBTHK Tokubetsu Hozon Certificate 


 This blade was signed by Jyokeshi Masa-Aki(城慶子正明) in the first year of the Bunkyu era(1861: the end of the Edo period). He was active in sword forging during the Kaei-early Meiji era(1848-1870). Jyokeshi Masa-Aki also signed as Takemura Tsuneemon Minamoto Masa-Aki (竹村恒右衛門源正明). It is the case with this blade.

 Masa-Aki was born in Tsuyama city in Okayama prefecture in the 11th year of the Bunka era(1814). His real name was Takemura Tsunejiro(竹村恒次郎). It was often the case that a swordsmith’s maker’s name and his birth name were completely different.

 From a childhood, Masa-Aki got sword-forging training from Hosokawa Masayoshi, being his apprentice. Hosokawa Masayoshi(細川正義) is a renowned swordsmith at the end of the Edo period. Hosokawa Masayoshi had learned sword-forging techniques under the master, Suishinshi Masahide(水心子正秀), one of the most skilled swordsmiths in Samurai history.
Masayoshi(Masa-Aki’s master) was extremely a skilled swordsmith, and he was good at forging blades with Choji Midare Hamon, which is the characteristic of the Bizen sword-forging style(BIZEN DEN). Masa-Aki also mastered this excellent sword-forging technique from his master. Choji Midare Hamon is an Irregular wavy tempering line, and you can see it in this blade as well. Most of Masa-Aki’s work reflects Bizen Den (One of the Five Japanese sword-forging traditions).

 Hosokawa Masayoshi(his master) and his son Mamori served the Matsudaira clan in the Sakushu Tsuyama domain(today’s Okayama prefecture). And Masa-Aki took over the position after they retired. He served the clan as a Hanko(藩工), who exclusively forged swords for a specific clan. He was also a Hanshi(藩士), who was a Samurai who worked under one clan or domain. Later on, Masa-Aki became an independent swordsmith in Edo city, being popular among high-class Samurai for his excellent craftsmanship. The signature also indicates that this blade was ordered by a Samurai. And, based on the fact that Masa-Aki was categorized as a top tier swordsmith, the person who ordered this blade must have been high-class.

 We believe Masa-Aki was inspired by the Nanbokucho style Okisaki blades when he created this work. Nanbokucho is the name of the period that lasted during 1337-1392. During this time, the Japanese imperial court was divided into north and south, fighting against each other. One of the most popular trends in Japanese swords back then was the Okisaki style, the strong-looking blade with a very long tip. Based on the look of this blade, Masa-Aki might have been inspired by this old style of swords. Many Japanese swordsmiths tried to recreate old-style swords from the previous era to improve their craftsmanship during the late Edo period. Masa-Aki is one of them.


 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.

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.

 Wild boars running in the bamboo groove are designed for this Fuchi Kashira. These motifs are colored with gold paint, and it remains in good condition. You could see tiny granular protrusions dots on the surface of this Fuchi Kashira. These dots were made by a type of chisel, and this decorative technique is called as the Nanako-Ji (魚子地) technique.

 In Japanese, there are expressions about wild boar. For example, the Inoshishi Musha (猪武者, Inoshisi is a Japanese name for the wild boar) means a Samurai who rushes without considering the circumstances of before and after. Or, the idiom Chototsu Moushin (猪突猛進) describes the figure of a reckless person who makes rapid progress toward the goal. When you hear it like this, you might get a strong impression that wild boar is a madcap animal. However, we can also interpret that this type of person could work hard on what he (or she) is aiming for. Also, in the war, it was necessary for Samurais to have the courage to get into the enemy’s land without regard for danger. So, the wild boars might have been applied to this Fuchi Kashira because its owner wanted to emulate the courage of wild boars.

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

 We believe it is the same motif of the Fuchi Kashira. That is, the wild boar. Their bodies have finished in glossy metal color (the color of its material), and their eyes are colored in gold. The former owner of this sword might have deeply cherished this brave animal motif.

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. 

 Oval-shaped Tsuba that has Kozuka and Kougai holes. On the front, you see a kind of fish-liked creature is designed. And it seems it bites roofing tiles. Seeing its figure, we think it is the Shachihoko (しゃちほこ). It is a decoration used for the roofs of castle towers and watchtowers. The Shachi (鯱) is an imaginary creature, and it is said it has a dragon or tiger’s head, and its body is a fish. Its tail bends toward the sky, and people associated its figure with the Hoko (鉾, an ancient form of Japanese long weapon). That is why this animal was named the Shachihoko. According to a theory, the Shachihoko would spit water out of its mouth when a building catches fire. Therefore, it has been put on the roof in many castles and temples in Japan. Since the fire was a big worry for wooden buildings, this Tsuba’s maker prayed for safety by applying such a design. Also, as we could find the mountain that looks like Mt. Fuji, there was probably an aim to give auspicious design for this work.

Saya Saya is the scabbard for the Japanese sword.
