Antique Japanese Sword Katana Signed by Tadakuni with NBTHK Tokubetsu Kicho Certificate
【Description】
Summary
This blade was signed by Shinano Daijo Fujiwara Tadakuni (信濃大掾藤原忠国), a renowned swordsmith in Tottori province. The swordsmith’s name Tadakuni lasted seventh generations until late Edo period (about 150 years ago).
The first-gen Tadakuni first signed Kunikatsu (国勝) and then changed it to Tokikuni (刻国). And he eventually used Tadakuni (忠国) as his maker’s name.
Also, Tadakuni was an apprentice of Dewa Daijyo Kunimichi (出羽大掾国路), whose master was Horikawa Kunihiro, one of the most famous swordsmiths in the early Edo period. Tadakuni originally forged swords in the Kyoto area (Yamashiro province), learning highly refined sword-forging techniques from his master. He moved to the Inaba domain in Tottori prefecture in the 1st year of the Kanei era (1624: Early Edo period) to serve the Ikeda clan as an Okakaekaji exclusively. Okakaekaji is a swordsmith who exclusively forged swords for a specific domain or clan. It is said that this was when he changed his maker’s name from Tokikuni to Tadakuni.
He received the title of Shinano Daijyo in 1634. Daijo is an honorable official title the imperial court gave for his excellent craftsmanship. From generation to generation, Tadakuni served the Ikeda clan. There is no doubt that the first-gen Tadakuni mastered the superb sword-forging technique. The swordsmith’s name Tadakuni lasted nine generations until the late Edo period (about 150 years ago).
*Please keep in mind that there are a couple of black rust and Hike Kizu (scratches) on this blade. If you like to know the detailed condition, please feel free to contact us.
【Blade】
Cutting Edge Length(Nagasa)：69.1 cm (27.2 inches)
Curvature(Sori)：1.4 cm (0.55 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.
The theme of this Fuchi Kashira is combination of Tora (虎, tiger) and Take (竹, bamboo) called Take-Tora zu (竹虎図). It is a popular and classical design. The tiger is a brave animal. A theory says people considered the tiger pattern would protect people from evil spirits. Therefore, its pattern has been treated as a talisman. The tiger design has also been regarded as the symbol of life activity when “tiger” is written by a Japanese Kanji character (漢字, a kind of Japanese letter) based on its meaning. It is said people wished boys’ healthy growth by using the tiger pattern. Bamboos grow neatly towards the sky, and it is vital so that this motif represents nobility and strength. Besides, the bamboo breaks straight, but its content is hollow; people thought it shows innocence. According to a Chinese legend, Houhou (鳳凰, Fenghuang) eats bamboo fruits; therefore, bamboo has been considered a sacred plant. Also, as it keeps its green color even in cold winter, people thought the bamboo pattern shows eternity and longevity. We would say that the bamboo pattern is one of the familiar designs for Japanese people since ancient times.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
The motif of this Menuki is Karajishi (唐獅子). The Shishi (獅子) means a lion in Japanese, and the Karajishi is a lion brought from the continent to Japan in the Toh period (唐, Tang dynasty, 618-907). The Karajishi typically has curly hair for its head, neck, body, and tail, as seen on this work. In Buddhism, the Karajishi is regarded as a symbol of wisdom, and Monju Bosatu (文殊菩薩, Manjushri Bodhisattva) rides lions. According to a theory, the Karajishi is the origin of Komainu (狛犬, stone guardian dogs that exorcize evil spirits). It shows this animal motif has been familiar to Japanese people since ancient times.
There is a Houwa (法話, Buddhist monks tell the story of Buddhism in an easy-to-understand manner) that treats the Karajishi and this flower. The lion is called the king of the beasts. However, even this invincible animal has only one fear: a bug in the lion’s body. This pest grows in the lion’s hair and eventually breaks the skin and bites the flesh. Nevertheless, it dies if it is exposed to the night dew of a peony. Therefore, the lion rests under peony flowers at night, looking for a haven. The design of these sword mountings might have been quoted from this story.
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.
Karajishi is depicted with pine trees (松, Matsu) and waves (波, Nami) on this Tsuba. Pine trees often grow near the seashore. As pine trees keep their green color throughout the years by withstanding severe heat and cold, people thought this plant pattern represents eternal youth. Furthermore, its color is called Tokiwa-Iro (常盤色, evergreen trees’ dark green color with brown), and pine trees have another name “Tokiwa-Gi (常盤木).” Tokiwa means immutability, so Tokiwa-Iro is a color that praises green with a wish for longevity and prosperity. It is said this color was appreciated, especially in the Edo period, as a good-luck color. The pine tree design gives us an elegant and noble impression; it might be another reason that people love this motif.
Also, as waves’ movements continue endlessly, the wave pattern represents eternity, immortality, longevity, birth, etcetera. Also, since tides repeatedly change the shape and terrain of rocks, some people hoped for a strong will by using this motif. People used this pattern wishing for an indomitable spirit to rechallenge time and time without giving up. Thanks to its dynamic design, this motif has been appreciated, especially for men’s Kimono (traditional Japanese costume).
Saya： Saya is the scabbard for the Japanese sword.
This Saya has a design with numerous diagonal lines. Also, the head of this Saya is decorated with a paulownia (桐, Kiri) pattern. The Kiri pattern is generally composed of three standing straight inflorescences and three leaves. The number of flowers that are blooming at each inflorescence means the ranks of this design. It is also famous that one of the most popular Samurais in Japan: Toyotomi Hideyoshi used the Kiri pattern for his family crest. According to a theory, Hideyoshi used Omodaka (沢瀉, arrowhead) pattern as his family crest. However, Oda Nobunaga, a well-known military commander in the Warring States period, permitted Hideyoshi to use Kiri design. This plant pattern was once used by the imperial family and national leaders of the time. Today, this plant pattern is used as the crest of the Japanese Government.
