Antique Japanese Sword Katana Signed by Fujiwara Nobusada with <\/span>Tokubetsu Hozon<\/span> <\/span>Certificate<\/span>\u00a0<\/span><\/strong><\/p>\n

\u3010Description\u3011<\/strong><\/span><\/p>\n

Summary<\/strong><\/p>\n

\u00a0This blade was signed by Yamato no Kami Fujiwara Nobusada (\u5927\u548c\u5b88\u85e4\u539f\u5ba3\u8c9e), who was especially active in Higo province (today’s Kumamoto prefecture) during the Kan-Ei era (1624-1644: Early Edo period). He is known as an offspring of the Enjyu (\u5ef6\u5bff) school members. The maker’s name, Nobusada, lasted two generations, and the first-gen created this blade because the second-gen was active during the Genroku era (1680-1709). It is said that the first-gen Nobusada also forged blades in Buzen (today’s Oita prefecture).\u00a0 He served Higo Hosokawa clan as an Okakaekaji. Hosokawa clan was a famous feudal lord who was the head of Kumamoto castle during the Edo period. Considering this fact, we presume Nobusada’s craftsmanship was highly acknowledged, and he must have forged blades for those who served this clan during the early Edo period.\u00a0 During his career, he received an honorable official title, Yamato no Kami for his excellent sword-forging techniques from the imperial court.\u00a0<\/span><\/p>\n

\"\" \"\"<\/p>\n

What is Enjyu school?\u00a0<\/strong><\/p>\n

\u00a0Enjyu (\u5ef6\u5bff) is the prestigious school\u2019s name that flourished during the late Kamakura period-Nanbokucho period (Late 13th-Early 14th century) in Higo province (today\u2019s Kumamoto prefecture). Enjyu school was founded by Kunimura (\u56fd\u6751), who is said to have been the grandson of Rai Kuniyuki from Yamashiro province (today\u2019s Kyoto prefecture).\u00a0<\/span><\/p>\n

\u00a0Kunimura and his apprentices moved from Yamashiro province to Higo province (today\u2019s Kumamoto prefecture in Kyushu island) after being invited by the Kikuchi clan, who had an influential power in that region. It is said that the 10th head of the Kikuchi clan, Kikuchi Takefusa (\u83ca\u6c60\u6b66\u623f), had to find skilled swordsmiths who could forge strong swords to combat the Mongolian army. Back then, Japan was targeted by the Mongolian emperor, and Kyushu island is where the battle was taking place twice (1274 and 1281). To prepare for the second attack from the Mongols, Kikuchi Takefusa brought Kunimura and his apprentices from Kyoto. Since then, Kunimura and his sons served as Okakaekaji for this clan, exclusively forging swords for the Kikuchi clan, which ruled the Higo province back then.<\/span><\/p>\n

\u00a0All the swordsmiths from Enjyu school used the letter \u201c\u56fd\u201d (Kuni) for their maker\u2019s name. The descendant of this school founded the famous sword school named Dotanuki (\u540c\u7530\u8cab). And there are descendants of the Enjyu school\u2019s swordsmiths throughout the Edo period. That means Enjyu school had over 500 years of its history.<\/span><\/p>\n

\u00a0When Enju school flourished in the Nanbokucho period, Japan was tumultuous because the imperial court was split into two sides (south and north). There were many conflicts, and many Samurai were deployed. And Enju school must have dedicated themselves to forging high-quality blades for those Samurai who fought in battles.\u00a0<\/span><\/p>\n

\u00a0The name \u201cEnjyu\u201d is written as \u5ef6\u5bff in Japanese. If you translate the word literally, it means extending life span, which was construed as good luck among feudal lords. Therefore, the swords were presented among Samurai as good gifts.<\/span><\/p>\n

Appraisal<\/strong><\/p>\n

\u00a0It is appraised as a Tokubetsu Hozon Token <\/strong>(\u7279\u5225\u4fdd\u5b58\u5200\u5263) issued by NBTHK (Nihon Bijutsu Touken Hozon Kyokai:\u65e5\u672c\u7f8e\u8853\u5200\u5263\u4fdd\u5b58\u5354\u4f1a). This authentication paper was only given to authentic Japanese swords, especially well preserved and high quality with artistic value.<\/span><\/p>\n

\u00a0Japanese 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.<\/span><\/p>\n

Koshirae<\/strong><\/span>\uff1a<\/span>Koshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya(Scabbard), Tsuka(Handle), Tsuba(Handguard).<\/span><\/strong><\/span><\/p>\n

\u00a0The sword mountings of this Katana\u2019s Koshirae are related to one motif: Tonbo (\u873b\u86c9, dragonfly). Dragonflies have been inhabited in Japan for a long time. As this insect bag preys quickly, its heroic figure was sometimes the object of belief. During the Warring States period, the dragonfly was called the Kachimushi (\u52dd\u3061\u866b, winning insect) because of its fearless character. Dragonflies fly around fast to catch pests, moving only forward, not backward. Therefore, people thought the behaviors of this insect showed the spirit of Futaiten (\u4e0d\u9000\u8ee2); it is a state of mind or a state in which a person has some conviction and does not give in to difficulties. It is very persuasive that Samurai warriors cherished this design as an auspicious motif because of the spirit that Samurai should be prepared for the battlefields. Not only for sword mountings, dragonfly patterns were also incorporated into various items such as helmets, armor, battle coats, etcetera.<\/span><\/p>\n
