Antique Japanese Sword Tanto Signed by Nobukuni Yoshimasa  with Hozon Certificate 

【Description】

 This blade was signed by Nobukuni Yoshimasa (信国義昌) in February 1828 in Chikuzen province (today’s Fukuoka Prefecture). Yoshimasa (義昌) is the name of the swordsmith and Nobukuni (信国)is the name of the school he belonged.

 Those who belonged to Nobukuni School in Chikuzen province were called Tsukushi Nobukuni, one of the most prospered sword forging schools in Kyushu island during the Edo period.

 Since this blade was registered in Fukuoka, we assume that the descendants of a Samurai residing in this area had been passing it down for generations. 

The Foundation of Nobukuni School

 The Nobukuni school was initially founded by the first generation Nobukuni in Kyoto. The school stayed there for a few generations. However, the 4th generation Nobukuni SADAMITSU had to evacuate Kyoto city because the battle between the south emperor court and the north emperor court became severe. And as a result, Kyoto city was burnt(in the late 1300s). We called it the Nanbokucho war when the Japanese imperial court was separated into two.

 Nobukuni SADAMITSU managed to escape and arrive at Usaha(Ohita prefecture)to serve the Ajimu clan. Nobukuni school prospered there from third to 11th generation. However, Toyotomi Hideyoshi, one of the three unifiers of Japan, destroyed the Ajimu clan during the late Azuchi Momoyama period (1582). And the 12th generation Nobukuni YOSHISADA moved to Chikuzen(Fukuoka prefecture), being invited by Kuroda Nagamasa, a famous feudal lord who served Toyotomi Hideyoshi (1602). It is said that the second-gen Yoshimasa also followed his father. Since then, Nobukuni school had been under the auspices of Kuroda clan for generations during the Edo period, and they exclusively forged for this clan.

 Yoshimasa belonged to the latter generation of this long-established school, so it can be said that this blade inherits many of the fine techniques of this school.

 

 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.

Kissaki: Kissaki is the tip of the Japanese sword.

 

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.

 The theme of this Fuchi-Kashira is moon. The sun and the moon have been treated as objects of worship since ancient times. Some people considered them the symbol of authority. The moon pattern has various shapes depending on the waxing and waning of the moon: full moon, half-moon, crescent, or hazy moon.

 There is also the idea: as the moon changes its shape depending on its fullness, it represents growth and development. Moreover, the moon is a classic design that symbolizes autumn: the combination of a moon with rabbits, deer, autumn grass, waves, etcetera.

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

 The theme of this Menuki is a catfish. It is a fish with a large head and mouth, two beards, and a slimy body without scales. Catfishes are nervous and delicate, so they react sensitively to small shakes and violate or jump. For that reason, after the middle ages in Japan, people thought that a catfish was the cause of earthquakes because they could feel tiny shakes that nobody could realize.

 The catfish pattern was described often in the Edo period. About catfish, there is a famous theme of ink painting that is called Hyoune Zu (瓢鯰図). It depicts a man trying to keep Namazu (鯰, catfish) with Hyoutan (瓢箪, gourd). It is a question and answer of Zen Buddhism. It is thought this theme came from the proverb that means to succeed having difficulty. Since the motifs of sword mountings sometimes reflect the taste of its owner or his view of religion, the owner of the Tsuba with catfish motif was possibly involved in Zen Buddhism.

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. 

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

 The theme of this Kozuka is seashells. This pattern is a combination of different types of seashells. It is often designed with a seaside scene or wave pattern. You would feel the refreshing atmosphere of summer. Bivalves, especially clam, its shells cannot be combined with any other clam’s frame; therefore, its pattern represents happy marriage.

 Seashell is called Kai (貝) in Japanese. Because of its pronunciation, the seashell has another meaning. There is a word Yarigai (やりがい, worthwhile). As a part of this word has the same accent as Kai (貝 is read Gai in some cases), Japanese people found this meaning. Also, since seashells are hard and combine only with their pair, people thought it represented a robust defense. Due to these meanings that inspire warriors who go to the battlefields, Samurais might have loved this motif.

Saya Saya is the scabbard for the Japanese sword.  

Authentication PaperNBTHK Hozon Certificate for the blade (No. 3031819)

  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 May 31th in the 5th year of Reiwa (2021). They appraised it as Tokubetsu Hozon Touken, the blade worth preserving for Japanese society.
