Antique Japanese Sword Tanto signed by Jokeshi Masanori with NBTHK Hozon Certificate
【Description】
Summary
This blade was made in November of the first year of the Meiji period (1868) by Jyokeshi Masanori (城慶子正則) in Edo, Musashi province (today’s Tokyo). The swordsmith, Jyokeshi Masanori, was active from the late Edo period to the early Meiji period. He is the son of Jyokeshi Masa-aki (城慶子正明), a top disciple of Hosokawa Masayoshi. Masanori was also known by the name Ishizuka Asajirō. Also, because the government banned the wearing of swords starting on March 28, 1876, swords made by him during the Meiji period are quite rare. This Tanto is rare, because it has a straight, double-edged blade, giving it the appearance of a classical sword Tsurugi (剣).
Jokeshi Masa-aki
Jokeshi Masa-aki (城慶子正明 ) 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. 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 end of Edo period
The Bakumatsu period (幕末) was the final part of Japan’s Edo period, lasting from around 1853 to 1868. It began when American ships led by Commodore Perry arrived in Japan and encouraged the country to open its ports to international trade. This moment was a turning point in Japanese history. Many people in Japan were surprised by Western technology and started thinking about how the country should respond to the changing world.
At the time, there were strong debates between those who supported the traditional Tokugawa shogunate and others who believed Japan needed to modernize and return political power to the Emperor. These disagreements eventually led to conflict and the end of samurai-led government.
Samurai were important figures during the Bakumatsu period. Their swords, known as Katana, were not just weapons but also powerful symbols of their values and way of life. However, as Japan began to build a modern army and adopt new weapons, swords became less common in battle. The Bakumatsu period ended with the Meiji Restoration in 1868, which began Japan’s transformation into a modern nation.
This blade is appraised as a Hozon Touken (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.
*Please keep in mind that there are some light black rusts on this blade. If you like to know the detailed condition, please feel free to contact us.
【Blade】
Cutting Edge Length (Nagasa): 16.3 cm (6.41 inches)
Curvature (Sori): 0 cm (0 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.
Kissaki: Kissaki is the tip of the Japanese sword.
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.
Tsuka and Menuki: Tsuka is the handle of the Japanese sword and Menuki is its decoration.
This Menuki has a morning glory (朝顔, Asagao) on the front side and a praying mantis (カマキリ, Kamakiri) on the back. In Japan, the morning glory came from China as a medicinal plant around the Nara period. Later, during the Edo period, it became popular as a decorative flower. Because it blooms in the morning and fades quickly, it is seen as a symbol of summer and the shortness of life.
The praying mantis is a helpful insect that eats pests in the fields. It is also known for its strong and careful posture, so it can be used as a symbol of alertness and readiness to fight.
By using these two different motifs, the design may show not only a sense of season but also the mindset of the Samurai who owned the sword.
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.
Saya: Saya is the scabbard for the Japanese sword.
The clouds are depicted on this Saya. Clouds bring rain and snow, and their movements significantly affect the weather of the day. Due to its supernatural power, a theory says that gods, spirits, and dragons dwell in the clouds.
The cloud pattern has been associated with magical power, and people thought it an omen of lucky things. In addition, some people wished to obtain a leisurely life in comfort by seeing clouds’ movements (that floats in the sky). Or, as clouds appear repeatedly, its design represents reincarnation. Samurais were always on the verge of life and death on the battlefield. They might have believed in the power of this pattern. And they had incorporated it into the design of their sword mountings, such as Tsuba.
Authentication Paper: NBTHK Hozon Certificate for the blade (No.3034833)
