Antique Japanese Sword Tanto Signed by <\/span>Ise Daijyo Yoshihiro<\/span> with NTHK Kanteisho\u00a0<\/span>Certificate<\/span><\/strong><\/span><\/p>\n

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

\u00a0This blade was signed by Ise Daijyo Yoshihiro (\u4f0a\u52e2\u5927\u63be\u5409\u5e83), who was especially active during the early Edo period (mid-late 17th century) in Hizen province (Today\u2019s Saga prefecture). He was an apprentice of the first-gen Tadayoshi, one of the most famous swordsmiths during the early Edo period. Yoshiro\u2019s work has a close resemblance to his master Tadayoshi. His birth name was Yoshizaemon (\u5409\u5de6\u885b\u9580). He received an honorable official title of Ise Daijyo from the emperor for his excellent craftsmanship during the Kanbun era (1661-1673).<\/span><\/p>\n

The first-gen Tadayoshi (His master)<\/strong><\/p>\n

\u00a0The first-gen Tadayoshi was born and raised in the Saga domain. In 1596, under the domain\u2019s order, he went to Kyoto to learn the sword-forging technique from Umetada Myojyu(\u57cb\u5fe0\u660e\u5bff), one of the greatest swordsmiths in the early Edo period. He improved his craftsmanship and returned to the Saga domain two years later (1598). The first head of the Nabeshima clan, Nabeshima Katsushige, appreciated the work of the first-gen Tadayoshi very much. Then, Katsushige appointed him as his Okakaekaji, a swordsmith who exclusively forged swords for a specific domain or clan. And Tadayoshi started to stay near Saga castle, the Nabeshima clan\u2019s headquarters. And he founded Hizen Tadayoshi school, which trained more than 100 swordsmiths during the Edo period. Yoshihiro is one of them.<\/span><\/p>\n

Hizen Province<\/strong><\/p>\n

\u00a0The swordsmiths in the Hizen province worked under the auspices of the Nabeshima clan, a powerful feudal family. They produced beautiful Jigane (steel surface)-patterned blades, also known as Hizen To, using and mixing carbon steel made in western countries. Hizenkoku had been flourishing through international trading. The geographic location of this domain made it possible to have easy access to western carbon steel.<\/span><\/p>\n

Horimono<\/strong><\/p>\n

\u00a0The blade of this Katana has beautiful engravings of Bonjis (\u68b5\u5b57) and Gomahashi (\u8b77\u6469\u7bb8)\u00a0 on both sides.<\/span><\/p>\n

\u00a0Bonji (\u68b5\u5b57) is Sanscrit characters carved into the blade invoking Buddhist deities. Sword carvings often depict Fudo Myo-O (\u4e0d\u52d5\u660e\u738b, acalan\u0101tha) or his incarnations, and there are also Sanskrit characters that represent this god. Among the various Buddhist Buddhas, Fudo Myo-O was deeply worshiped by Samurai warriors. According to a theory, this god is the incarnation of Dainichi Nyorai (\u5927\u65e5\u5982\u6765, Mah\u0101vairocana, the principal image of esoteric Buddhism). Perhaps the most common type of Sanskrit character carved on the blades is the character \u201cKahn (\u30ab\u30fc\u30f3)\u201d, which means Fudo Myo-O. There is also a Sanskrit character called \u201cKanmarn (\u30ab\u30f3\u30de\u30fc\u30f3),\u201d which is combined with the word \u201cMan.\u201d There was once a trend that Samurai warriors incorporated motifs with religious meaning into their battle costumes, such as armor and helmets, and this sword carving was also a way to express their religious beliefs.\u00a0<\/span><\/p>\n

\u00a0Gomahashi (\u8b77\u6469\u7bb8) is a horimono in the form of the ritual chopsticks used in both Shinto and Buddhist rites.\u00a0<\/span><\/p>\n

\"\"<\/p>\n

Nakago<\/strong><\/span>: Nakago is the tang of the Japanese sword.<\/strong><\/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

\"\"<\/p>\n

 <\/p>\n

Koshirae<\/strong>:<\/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 theme of this menuki is the Hanabishi family crest (\u82b1\u83f1\u7d0b). The Hanabishi design features four flower petals arranged in a diamond shape. It has been used on clothing and personal items by nobles for over 1,000 years. One famous samurai family that used this crest was the Takeda clan. Also, this menuki is a rare sliding type.<\/span><\/p>\n

\u00a0<\/span>\"\" \"\"<\/p>\n

Tsuba and Habaki<\/strong>: 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.\u00a0<\/strong><\/span><\/p>\n

\"\" \u00a0\"\"<\/p>\n

Saya<\/strong>: <\/span>Saya is the scabbard for the Japanese sword<\/strong><\/span><\/p>\n

\u00a0This scabbard is covered with black lacquer. Due to its high waterproof effect, lacquer has been used since ancient times in Asia. The blade of a Japanese sword is made of iron, and moisture is the greatest enemy of iron. For the purpose of carrying the blade without degrading it, people devised a method of coating the scabbard with lacquer. To prevent not only moisture but also rain and snow from penetrating the inside of the scabbard, it was necessary to apply multiple layers of lacquer. The Nushi (\u5857\u5e2b, lac<\/span>querers) was born precisely because advanced techniques were required to handle the complicated processes.<\/span><\/span><\/p>\n

\u00a0There is an Aoi No Mon design on this Saya. \u00a0It is a plant pattern in which each stem branches and has characteristic heart-shaped leaves. And today, it is known as the family crest of the Tokugawa Shogunate family led by Tokugawa Ieyasu (\u5fb3\u5ddd \u5bb6\u5eb7, 1543-1616), a famous military commander of the Warring States period. This plant pattern has also been used for the crest of the Kamo shrine in Kyoto prefecture. As mentioned above, the famous Shogunate family, the Tokugawa family, had their family crest with three leaves of Aoi due to their relationship with the Kamo shrine. As its leaves have a habit of always facing the sun, and the word \u201cAoi\u201d is taken as \u201cAogu (\u4ef0\u3050, looking up)\u201d for the sun, people thought the Aoi pattern would bring good fortune.\u00a0<\/span><\/p>\n

Authentication Paper<\/strong>: <\/span>NTHK Kanteisho Certificate for the blade (No. 12878)\u00a0<\/strong><\/span><\/p>\n

\u00a0NTHK<\/span><\/a>, also known as NPO Nihon Touken Hozon Kai, is the oldest organization for sword authentication of Japanese swords in modern times. It was established in 1910 during the post-Samurai era. They authenticated the blade on March 16th in the 7th year of Reiwa (2025). The purchaser will receive these original certificates as well.

Registration Number<\/span><\/strong>: Yamaguchi 28645<\/strong><\/span><\/span><\/p>\n

\u00a0The Board of Education in Yamaguchi prefecture issued a registration paper for this sword. It is called Jyu Hou Token Rui Torokusho (\u9283\u7832\u5200\u5263\u985e\u767b\u9332\u8a3c). Bunkacho (The Agency for Cultural Affairs) acknowledges a Japanese sword with this paper as a work of art.
\n\u00a0The sword needs to be traditionally hand-forged and made of Tamahagane carbon steel to be registered in the system. With this paper, its owner in Japan can legally own an authentic Japanese sword. Based on this registration number, we will apply for its export permit.
