The maker\u2019s name Tadatsuna lasted a few generations, and we assume it was forged by the second-gen, judging from the characteristic of the signature on the tang. The second-gen Tadatsuna was active in the early Edo period (Late 17th century), and he is one of Osaka\u2019s most skilled and popular swordsmiths in the early Edo period, following Tsuda Sukehiro and Inoue Shinkai. These three sword makers are called Sanketsu of Osaka Shinto.<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0The second-gen Tadatsuna was born in 1644 as the first son of the first-gen Tadatsuna, who called himself the descendant of Awataguchi Kunitsuna, a famous swordsmith in the early Kamakura period. His father was born in Hyogo prefecture and forged swords in Ushiroyama castle in Mie prefecture. Eventually, the first-gen Tadatsuna moved to Osaka. The second-gen Tadatsuna\u2019s real name is Asai Mandayu. The swordsmith\u2019s name Tadatsuna lasted three generations, and the second-gen is said to have been the most famous and skilled one. And he was not only excellent at forging swords with different kinds of tempering lines (Hamon) but also excellent at inscribing sculptures on his work.<\/span><\/p>\n<p><span style=\"color: #000000;\"><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\" \/><\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0The second-gen Tadatsuna first signed as Tadakuni (\u5fe0\u56fd). According to his remaining work, he started to forge swords in 1672 and kept creating his blades until he was about 80 years old (1716). He received the honorable title of Omi no Kami during Enpo era (1673-1680). He started to sign Ikkanshi Tadatsuna after the second year of Genroku era (1689).<\/span><br \/>\n<span style=\"color: #000000;\">During the early Genroku era, he used \u7e04 letter instead of \u7db1 when signing his creation, but after the mid-Genroku era, he used \u7db1 to sign his blades. Since this blade was signed as \u5fe0\u7e04, we can assume it was forged around the late 17th century. Genraoku period lasted 1688-1704. He kept forging swords for about 50 years in his career.<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0One of Tadatsuna\u2019s works is designated as Important Cultural Property of Japan. His swords are Ryuwazamono and Shinto Jyojyo Saku (Highly ranked swords among Japanese sword experts).<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0There is one interesting historical incident related to the work of the second-gen Tadatsuna. It was March 24th in the 4th year of Tenmei (1784). Sano Zenzaemon, A direct retainer of Shogun, attacked a son of Tanuma Okitsugu, who was the chief minister of the Edo government. Sano used a wakizashi signed by the second-gen Tadatsuna. The son was eventually died, and Sano was ordered to do Seppuku for his misconduct. Interestingly, since this incident happened, the price of rice decreased dramatically after the sharp rise, which suffered many people. And, people started to worship Tadatsuna\u2019s swords as Yonaoshi Daimyojin, a Great God that makes the world a better place. The Tadatsuna\u2019s popularity skyrocketed, and this incident is much talked about when you learn about the work of Tadatsuna. It is said that only noble high-class Samurai could afford to buy a sword forged by the Tadatsuna during the Edo period.<\/span><\/p>\n<p><span style=\"color: #000000;\"><strong>Osaka Shinto<\/strong><\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0The blades forged by Tadatsuna are categorized as Osaka Shinto. Shinto is Japanese Sword terminology that refers to the swords forged during 1596-1781. The blades made in the Osaka area during this period are called Osaka Shinto. There are many famous swordsmiths in this Osaka Shinto era. After Hideyoshi Toyotomi built Osaka castle, Osaka city flourished as a castle town and became the business center. Many swordsmiths moved to Osaka to look for better opportunities. They not only forged swords for those Samurai who lived in Osaka but also for feudal lords nationwide. Ikanshi Tadatsuna (Awataguchi Omi no Kami Tadatsuna), Inoue Shinkai, and Tsuda Sukehiro are the most famous among many swordsmiths.<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0One of the most notable characteristics of Osaka Shinto is its beauty in Jigane. Jigane is a visible steel surface pattern created by folding and hammering during the forging process), which made it possible by the location of Osaka. Osaka had close access to the Tamahagane (special carbon steel to make Japanese swords) production sites. The swordsmiths residing in Osaka were able to get high-quality carbon steel from these sites.<\/span><\/p>\n<p><strong>Horimono (Engraving)<\/strong><\/p>\n<p data-start=\"2079\" data-end=\"2533\"><span style=\"color: #000000;\"> <img loading=\"lazy\" decoding=\"async\" class=\" wp-image-4474 alignnone\" src=\"https:\/\/www.samuraimuseum.jp\/shop\/wp-content\/uploads\/2025\/11\/hori-2.jpg-\u306e\u30b3\u30d4\u30fc-2-scaled.jpg\" alt=\"\" width=\"250\" height=\"250\" \/> <img loading=\"lazy\" decoding=\"async\" class=\" wp-image-4474 alignnone\" src=\"https:\/\/www.samuraimuseum.jp\/shop\/wp-content\/uploads\/2025\/11\/hori2-2.jpg-\u306e\u30b3\u30d4\u30fc-2-scaled.jpg\" alt=\"\" width=\"291\" height=\"291\" \/><\/span><\/p>\n<p data-start=\"2079\" data-end=\"2533\"><em><span style=\"text-decoration: underline;\"><strong>*Please keep in mind that there are a couple of Kitae Kizu on this blade.

One well-known theme often found in sword mountings is the Genpei Kassen (\u6e90\u5e73\u5408\u6226, Genpei War). Although we cannot determine with certainty whether this particular piece illustrates that specific conflict, we would like to introduce the Genpei War as a possible reference and share a famous chapter of Samurai history with you.<\/span><\/p>\n<p data-start=\"572\" data-end=\"1152\"><span style=\"color: #000000;\">\u00a0The Genpei Kassen does not refer to a single battle, but rather a series of civil wars fought across Japan over a six-year period, from 1180 to 1185.<\/span><br data-start=\"723\" data-end=\"726\" \/><span style=\"color: #000000;\">It is also known as the Jish\u014d\u2013Juei no Ran (\u6cbb\u627f\u5bff\u6c38\u306e\u4e71). This conflict was fought between two powerful clans: the Minamoto (\u6e90, Genji) and the Taira (\u5e73, Heike).<\/span><br data-start=\"875\" data-end=\"878\" \/><span style=\"color: #000000;\">It began when Prince Mochihito (\u4ee5\u4ec1\u738b) called upon the Minamoto warriors to overthrow the Taira clan. Although Mochihito was defeated and died in 1180, the Minamoto forces continued fighting and gradually gained the upper hand, defeating the Taira in numerous engagements.<\/span><\/p>\n<p data-start=\"1154\" data-end=\"1433\"><span style=\"color: #000000;\">\u00a0The final decisive battle took place in 1185 at Dan-no-Ura (\u58c7\u30ce\u6d66), where the Minamoto clan achieved complete victory. This marked the downfall of the Taira, who had once dominated the imperial court, and it became one of the most iconic climaxes in Japanese Samurai history.<\/span><\/p>\n<p><span style=\"color: #000000;\">\u00a0<\/span><br \/>\n<img loading=\"lazy\" decoding=\"async\" class=\" wp-image-4478 alignnone\" src=\"https:\/\/www.samuraimuseum.jp\/shop\/wp-content\/uploads\/2025\/12\/tuka3-1.jpg-\u306e\u30b3\u30d4\u30fc-1-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><em><span style=\"text-decoration: underline;\"><strong>*Please keep in mind that the Tsuka Maki (thread on the handle) is quite aged<\/strong><\/span><\/em>.<\/p>\n<p data-start=\"860\" data-end=\"987\"><span style=\"color: #000000;\">\u00a0The menuki seems to depict a\u00a0\u00a0Dragon (\u9f8d, Ryu) as a motif of this menuki. <\/span><\/p>\n<p data-start=\"860\" data-end=\"987\"><span style=\"color: #000000;\">\u00a0Initially, 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\/12\/tuka-1.jpg-\u306e\u30b3\u30d4\u30fc-1-scaled.jpg\" alt=\"\" width=\"299\" height=\"299\" \/>\u00a0 \u00a0 <img loading=\"lazy\" decoding=\"async\" class=\" wp-image-4478 alignnone\" src=\"https:\/\/www.samuraimuseum.jp\/shop\/wp-content\/uploads\/2025\/12\/tuka2-1.jpg-\u306e\u30b3\u30d4\u30fc-1-scaled.jpg\" alt=\"\" width=\"302\" height=\"302\" \/><\/p>\n<p>&nbsp;<\/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.

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.
