His real name was Gassan Yahachir\u014d (\u6708\u5c71\u5f25\u516b\u90ce), and he was born in Dewa Province (today&#8217;s Yamagata Prefecture) in 1781. According to the NBTHK (Society for the Preservation of Japanese Art Swords), the inscription indicates that this blade was made upon request from Orii Masatsugu while Sadayoshi was still living in his birthplace of Dewa.<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0The name \u201cGassan\u201d refers to the swordsmith school to which he belonged. The Gassan school originated in the late Heian period (12th century), and its name is said to have come from Mt. Gassan, a sacred mountain in Dewa Province, where the school\u2019s early smiths forged their swords.\u00a0In his youth, Sadayoshi learned the art of sword-forging from his father, Okuyama Yasabur\u014d Sadachika (\u5965\u5c71\u5f25\u4e09\u90ce\u8c9e\u8fd1), who was believed to be a descendant of the \u014csh\u016b Gassan school, one of the oldest Gassan lineages.<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0Around the age of twenty, Sadayoshi moved to Edo (present-day Tokyo) and became an apprentice to the renowned master Suishinshi Masahide (\u6c34\u5fc3\u5b50\u6b63\u79c0), one of the most celebrated swordsmiths of the late Edo period and the key figure in the Shinshint\u014d (\u201cNew New Sword\u201d) revival movement.\u00a0<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0After about ten years of training, Sadayoshi mastered advanced techniques and, in 1833 (Tenp\u014d 4), relocated to Osaka. There he founded the Osaka Gassan school, further refining his craft and training many talented apprentices, several of whom went on to become leading swordsmiths of the Bakumatsu era (the end of the Edo period).<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-4474 alignnone\" src=\"https:\/\/www.samuraimuseum.jp\/shop\/wp-content\/uploads\/2021\/08\/settsu_OCMOJ_0802.jpg\" alt=\"\" width=\"595\" height=\"350\" \/>\u00a0<img loading=\"lazy\" decoding=\"async\" class=\" wp-image-4474 alignnone\" src=\"https:\/\/www.samuraimuseum.jp\/shop\/wp-content\/uploads\/2021\/07\/settsu_JMAP_0709.jpg\" alt=\"\" width=\"350\" height=\"350\" \/><\/p>\n<p><span style=\"color: #000000;\">\u00a0Although the Gassan school had been one of Japan\u2019s most prestigious traditions since the Kamakura period, its influence had declined by the mid-Edo period.<\/span><br \/>\n<span style=\"color: #000000;\">Through Sadayoshi\u2019s tireless efforts and accomplishments, however, the school was revived and regained its former prominence toward the end of the Edo period.<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0Sadayoshi adopted a son from the Tsukamoto family and named him Sadamitsu (Gassan Sadakazu, \u6708\u5c71\u8c9e\u4e00), who later became one of Japan\u2019s most famous swordsmiths of the Meiji era. <\/span><span style=\"color: #000000;\">Father and son devoted many years to researching the traditional Gassan forging techniques and eventually succeeded in recreating the Ayasugihada pattern\u2014an undulating grain on the steel surface resembling the grain of Japanese cedar, which became the signature texture of the Gassan school. <\/span><span style=\"color: #000000;\">In addition to Ayasugihada, Sadayoshi also forged blades in various other traditional styles.<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0Gassan Sadayoshi passed away in 1870 (the 3rd year of the Meiji era) at the age of 71. <\/span><span style=\"color: #000000;\">His adopted son Gassan Sadakazu inherited the tradition, which was then passed down to Gassan Sadakatsu, and the lineage continues to this day. <\/span><span style=\"color: #000000;\">The current head of the family, Gassan Kazutoshi, and his son Gassan Sadanobu, still carry on the centuries-old Gassan tradition, forging authentic Japanese swords in Nara Prefecture today.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Horimono (Engraving)<\/strong><\/p>\n<p data-start=\"231\" data-end=\"888\"><span style=\"color: #000000;\">\u00a0This blade features beautiful carvings (Horimono) on both sides.

The lotus flower symbolizes purity emerging from the mud, a key concept in Buddhist teachings. In sword ornamentation, the upper carving represents the lotus blossom, while the lower portion is the pedestal (Rendai).

Another Sanskrit character, \u201cKanm\u0101n\u201d (\u30ab\u30f3\u30de\u30fc\u30f3), combines with \u201cMan\u201d to form a sacred mantra.

A flaming dragon known as Kurikara Ry\u016b-\u014d (\u5036\u5229\u4f3d\u7f85\u7adc\u738b) coils around the blade, symbolizing the \u201cSword of Wisdom\u201d that cuts through ignorance, evil, and worldly desires.

TACHI was suspended loosely on the left waist with its edge facing the ground so that you could draw it faster to cut down soldiers on the ground.

It is not intended for practical combat; instead, its purpose was to signify the authority and dignity of the Samurai who carried it, or the powerful figures they served. As a result, it is characterized by the luxurious decorations and colors.<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0<\/span><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-4478 alignnone\" src=\"https:\/\/www.samuraimuseum.jp\/shop\/wp-content\/uploads\/2025\/11\/tuba_up-7.jpg-\u306e\u30b3\u30d4\u30fc-7-scaled.jpg\" alt=\"\" width=\"520\" height=\"125\" \/><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #008080;\"><strong>Fuchi-Kashira<\/strong><\/span>\uff1a<strong><span style=\"color: #000000;\">A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.<\/span><\/strong><\/p>\n<p><span style=\"color: #000000;\">\u00a0The Fuchi and Kashira are decorated with the same design. It is a pattern of curved and intertwined vines. This design is called the Karakusa (\u5510\u8349, arabesque) pattern. Other sword mountings and metal fittings of this Koshirae have the same design, such as the Tsuba, Ishiduki Kanamono (\u77f3\u7a81\u91d1\u7269, a fitting attached to protect the distal end of the scabbard), etcetera.<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0The Karakusa pattern is a design in which stems and leaves of vines are twined and make curves. Since ivy has a strong vitality and grows up without interruption, people regarded this design as a symbol of prosperity and longevity. Vine is called Tsuru (\u8513) in Japanese and has another pronunciation; \u201cMan.\u201d There is a word \u4e07 (it is also read Man), which means ten thousand. In the Karakusa pattern, leaves and vines are connected like Obi (\u5e2f, belt). The word \u201c\u5e2f\u201d can also be read as \u201cTai.\u201d Due to its pronunciation, the term \u201c\u4ee3 (Tai)\u201d is associated. From this word-association game, an idiom \u4e07\u4ee3 is associated, meaning a thousand generations. In other words, we could imagine that people used this design wishing prosperity and longevity for their clans for a long time.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-4478 alignnone\" src=\"https:\/\/www.samuraimuseum.jp\/shop\/wp-content\/uploads\/2025\/11\/tuka3-7.jpg-\u306e\u30b3\u30d4\u30fc-7-scaled.jpg\" alt=\"\" width=\"300\" height=\"300\" \/><\/p>\n<p><span style=\"color: #008080;\"><strong>Tsuka and Menuki<\/strong><\/span>\uff1a<span style=\"color: #000000;\"><b>Tsuka is the handle of the Japanese sword and Menuki is its decoration.<\/b><\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0The motif of this Menuki is the dragon. Initially, the dragon is an imaginary creature found in ancient Chinese traditions or myths. Furthermore, it is regarded as a symbolic beast of auspicious signs. Its body is likened to nine animals: antlers are deer, the head is a camel, eyes are demons, the neck is a snake, belly is Mizuchi (\u86df, mythical animal in Japan which looks like a snake and have a horn and four legs), scales are fish, claws are falcons, palms are tigers, and ears are cows. It was thought that the dragon would reign at the top of all animals because of its odd-looking appearance.<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0In ancient China, the dragon pattern was used for emperors\u2019 clothing so that people strictly defined its shape or even the number of nails. On the other hand, the dragon pattern does not have detailed rules to represent classes in Japan. However, still, it maintains its meaning as the all-purpose auspicious pattern.<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0Also, in Japan, there is a belief that worships dragon as a water god and is called Ryujin Shinkou (\u7adc\u795e\u4fe1\u4ef0). Since rice cultivation flourished in this country, water is always an essential resource. Therefore, the dragon motif has been familiar to Japanese people since a long time ago.\u00a0<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-4478 alignnone\" src=\"https:\/\/www.samuraimuseum.jp\/shop\/wp-content\/uploads\/2025\/11\/tuka-7.jpg-\u306e\u30b3\u30d4\u30fc-7-scaled.jpg\" alt=\"\" width=\"337\" height=\"337\" \/>\u00a0 \u00a0 <img loading=\"lazy\" decoding=\"async\" class=\" wp-image-4478 alignnone\" src=\"https:\/\/www.samuraimuseum.jp\/shop\/wp-content\/uploads\/2025\/11\/tuka2-7.jpg-\u306e\u30b3\u30d4\u30fc-7.jpg\" alt=\"\" width=\"317\" height=\"317\" \/><\/p>\n<p><span style=\"color: #008080;\"><strong>Tsuba and Habaki<\/strong><\/span>\uff1a<strong><span style=\"color: #000000;\">Tsuba is the handguard for the Japanese Sword and Habaki is the equipment to make the blade not touch its scabbard inside.
