\nHe produced many swords with the signature “Okachiyama Sanroku” (“At the base of Mount Okachiyama”), a location where Tokugawa Ieyasu once commanded his forces.
\nAt age 36, around the Koka era (1845\u20131848), he moved to Edo and became a pupil of Taikei Naotane.
\nThere, he studied swordsmithing in Edo Aoyama and later served as a resident swordsmith for the Kishu Tokugawa family.

Aoi Art\u2019s Comment:
\nOkachiyama (Fujiyama) Nagasada built a distinguished career as a private swordsmith for the Kishu Tokugawa family.
\nHe studied under Taikei Naotane, mastering the Soshu-den style and producing masterpieces such as this.
\nThis sword was made in Kyoto in Meiji 1 (1868), aiming to emulate the Hasebe school, and it shows magnificent craftsmanship.
\nIt exhibits a powerful presence with distinct Kinsuji appearing in the Hachu.
\nNagasada often used the signature “Okachiyama” or sometimes “Isetamaru”.
\nHe forged swords in Edo Aoyama and Kyoto, as seen in this piece.
\nA highly diligent craftsman, he evolved from a Mino style to Soshu-den, producing impressive swords.
\nThis particular work was intended to resemble Yamato-den styles such as Tegai Kanenaga or Toma.
\nEspecially around the Monouchi, the bright Suguha with deep Nioikuchi is excellent, reminding us of Kanenaga’s masterpieces\u2014very refined.
\nHis mastery of Soshu-den came from Taikei Naotane, with very similar characteristics.
\nNagasada crafted many Soshu-den and Yamato-den swords, and this piece notably balances the deep and shallow parts of the Nioikuchi.
\nWe highly recommend this piece.<\/p>\n

Additionally, there is an inscription on the Nakago (tang), which reads:
\n“Made at Edo Aoyama in Keio 4 (1868). Cutting test performed by Tachibana Kuranosuke.”<\/p>\n[For Your Reference]\nTachibana Kuranosuke (1820\u20131880) was a Kenjutsu\/Bujutsu master of the Ryuko school, active from the late Edo to early Meiji periods.
\nBorn in Watarai-gun (present-day Minami-Ise, Mie Prefecture) in Ise no Kuni, as the second son of Yokoji Ryozauemon.
\nHe was adopted by the Tamaru magistrate of the Kishu domain, but both adoptive parents died soon after.
\nHe studied Bujutsu under Naoi Katugorou of the Ryuko school in Tamaru.
\nAfter Naoi’s death, sword master Hayashi Rokunesuke from Bizen trained him in Kenjutsu.
\nIn Tempo 15 (1844), he was invited to Edo by Matsudaira Tadanori, a senior pupil of Naoi school, to become a Shihandai at his dojo.
\nHe later returned to Tamaru and opened his own dojo, teaching both Bujutsu and academics.
\nHis instruction was strict, attracting not only samurai but also farmers, and he taught thousands of students.
\nIn Ansei 5 (1858), he demonstrated his Kenjutsu before the Shogun Tokugawa Iemochi.
\nIn 1859, his student competed in a match against four other Kishu domain dojo schools, and the Ryuko school was officially recognized.
\nRyuko-ryu became the official style taught in the Kishu domain school.
\nIn June of Meiji 13 (1880), 119 of his students celebrated his 60th birthday by erecting a monument at Kotai Shrine in Miyako, Watarai-gun.
\nHowever, he passed away on November 11 the same year.
\n(Translated from Wikipedia by Aoi Art.)<\/p>\n

This is a masterpiece made in Edo Aoyama for Tachibana Kuranosuke, a renowned Bujutsu master of the late Edo period, still retaining Ububa.
\nPlease preserve it for the next generation.
\nThe sword exudes dignity, and the Koshirae was made during the same period.
\nWe definitely recommend this masterpiece for you.<\/p>\n
